Removal
1Loosen the wheel bolts, then chock the
front wheels. Raise the rear of the vehicle, and
support it securely on axle stands. Remove
the wheel(s).
2Remove the driveshaft (see Chapter 8), or
disconnect it from the final drive output
flange.
3Disconnect the rear brake hose from the
metal brake line at the bracket on the trailing
arm (see illustration). Note: For information
on disconnecting brake hose-to-metal line
connections, see Chapter 9. Plug the line and
hose, to prevent dirt ingress and loss of brake
fluid.
4Disconnect the handbrake cable (see
Chapter 9).
5Disconnect the lower end of the shockabsorber from the trailing arm (see Section 9),
and lower the trailing arm.
6Remove the trailing arm pivot bolts (see
illustration)and remove the trailing arm.
7Inspect the pivot bolt bushes. If they’re
cracked, dried out or torn, take the trailing
arm to an engineering works and have them
new ones fitted. Each bush has a larger
diameter shoulder on one end. Make sure this
larger diameter shoulder on each bush faces
away from the trailing arm, ie the inner bush
shoulder faces the centre of the vehicle, and
the outer bush shoulder faces away from the
vehicle.Refitting
8Refitting is the reverse of removal. Support
the trailing arm with a trolley jack, and raise it
to simulate normal ride height, then tighten
the nuts and bolts to the torque listed in this
Chapter’s Specifications. Be sure to bleed the
brakes as described in Chapter 9.

5Remove the ABS wheel sensor (if
applicable) from the trailing arm, and unclip
the sensor wire harness from the arm.
Position the sensor aside so it won’t be
damaged during removal of the trailing arm.
6If you’re removing the right trailing arm,
unplug the connector for the brake pad wear
sensor, if applicable.
7Disconnect the rear anti-roll bar from the
trailing arm (see Section 12).
8On 1983 and later models, remove one of
the rear axle carrier bolts (see illustration).
9Disconnect the shock absorber lower
mounting bolt (see Section 11).
10Remove the two trailing arm pivot bolts
and nuts, and remove the trailing arm from the
vehicle.
11Inspect the pivot bolt bushes. If they’re
cracked, dried out or torn, take the trailing

4On power steering models, remove the
banjo bolts and disconnect the power
steering pressure and return lines from the
steering gear. Place a container under the
lines to catch spilled fluid. Plug the lines to
prevent excessive fluid loss and
contamination. Discard the sealing washers
(new ones should be used when
reassembling).
5Disconnect the track rod ends from the
steering arms (see Section 17).
6Remove the nuts and bolts from the
steering gear mounting brackets (see
illustration). Discard the old nuts.
7Withdraw the assembly from beneath the
vehicle. Take care not to damage the steering
gear boots.
Refitting
8Refitting is the reverse of removal. Make
sure the marks you made on the lower
universal joint and the pinion shaft are aligned
before you tighten the clamping bolts for the
upper and lower universal joints. Use new
self-locking nuts on the steering rackmounting bolts, and new sealing washers on
the hydraulic line fittings. Tighten the
mounting bolts, the track rod end nuts and the
universal joint shaft clamping bolts to the
torque values listed in this Chapter’s Specifi-
cations.
9Lower the vehicle to the ground.
10On power steering models, fill the
reservoir with the recommended fluid (see
Chapter 1) and bleed the power steering
system (see Section 23).
11It’s a good idea to have the front wheel
alignment checked by a dealer service
department or qualified garage.
20 Steering linkage (5-Series)-
inspection, removal and
refitting
4
Inspection
1Raise the vehicle and place it securely on
axle stands.
2Firmly grasp each front tyre at the top and
bottom, then at the front and rear, and check
for play in the steering linkage by rocking the
tyre back and forth. There should be little or
no play in any of the linkage balljoints. Inspect
the Pitman arm, the idler arm, the centre track
rod, the inner track rods, the track rod ends
and the steering arms for any obvious
damage. Try forcing the linkage parts in
opposite directions from one another. There
should be no play between any of them. If any
of the parts are bent or damaged in any way,
or if any of the balljoints are worn, renew the
parts concerned.
Removal
3Before dismantling the steering linkage,
obtain a suitable balljoint separator. A two-jaw
puller or a wedge-type tool will work (although
the wedge-type tends to tear the balljoint
boots). Sometimes, you can also jar a balljoint
taper pin free from its eye by striking opposite
sides of the eye simultaneously with two large
hammers, but the space available to do this is
limited, and the balljoint stud sometimessticks to the eye because of rust and dirt.
There is also a risk of damaging the
component being struck.
4To remove the outer track rods, disconnect
the track rod ends from the steering arms (see
Section 17). Remove the nut that attaches the
balljoint on the inner end of each outer track
rod to the centre track rod (see illustration).
Using a balljoint separator, disconnect the
outer track rods from the centre track rod. If
you’re renewing the balljoint at either end of
the outer track rods, paint or scribe alignment
marks on the threads to mark their respective
positions as a guide to adjustment during
reassembly (see illustration 17.3).
5To remove the centre track rod, remove the
nuts that attach the centre track rod balljoints
to the Pitman arm and the idler arm, and use a
balljoint separator to disconnect the balljoints
from the two arms.
6To remove the Pitman arm, you’ll have to
remove the steering box first (see Section 21).
Look for match marks between the sector
shaft and arm. If there aren’t any, scribe a
mark across the bottom face of both parts.
Remove the Pitman arm pinch-bolt and nut,
then remove the arm with a puller.
7To unbolt the idler arm, first remove the
small cover bolted to the top of the subframe
crossmember. Put a spanner on the bolt, and
remove the nut recessed into the underside of
the subframe crossmember (see illustration).
Check the idler arm rubber bush for wear. If
it’s damaged or worn, renew it.
8Check each balljoint for excessive play or
stiffness, and for split or deteriorated rubber
dust boots. Renew all worn or damaged
balljoints. The inner and outer track rod ends
on the outer track rods can be renewed
individually; if either balljoint on the centre
track rod is damaged or worn, you must
renew the centre track rod.
Refitting
9Refitting is the reverse of the removal
procedure, but observe the following points:
a) Realign the match marks on the Pitman
arm and the steering box sector shaft
when reassembling them.
b) If you’re fitting new inner or outer track
rod ends on the outer track rods, position
them so that the match marks made
during dismantling are aligned, and make
sure they are equally spaced on each
side.
c) Position the track rod end balljoint studs
on the outer track rods at an angle of 90°
to each other.
d) Make sure the left and right outer track
rods are equal in length when they are
fitted.
e) Tighten all retaining bolts to the torque
values listed in this Chapter’s Specifi-
cations.
f) When reassembly of the linkage is
complete, have the front wheel alignment
checked, and if necessary, adjusted.

21 Steering box (5-Series)-
removal and refitting
4
Removal
Note:If you find that the steering box is
defective, it is not recommended that you
overhaul it. Because of the special tools
needed to do the job, it is best to let your
dealer service department overhaul it for you
(otherwise, fit a new unit). Removal and
refitting the steering box is outlined here.
1On 5-Series E28 (“old-shape”) models,
discharge the hydraulic system by depressing
the brake pedal about 20 times.
2Using a large syringe or hand pump, empty
the power steering fluid reservoir (see Chap-
ter 1).
3Raise the front of the vehicle and support it
securely on axle stands.
4Support the front of the engine with a trolley
jack. Place a block of wood between the jack
head and the sump to protect the sump from
damage.
5Remove the pivot bolts from the inner ends
of the front control arms (see Section 4).
6Remove the nuts from the left and right
engine mountings (see Chapter 2).
7Remove the mounting bolts (two on each
side on earlier models, three on each side on
later models) from the subframe crossmember
(see illustration)and remove the subframe.
8Remove the nuts and bolts that secure the
universal joint shaft to the steering box worm
shaft. Slide the universal joint shaft up and off
the worm shaft. Inspect the universal joint
shaft for wear. If it’s stiff or worn, renew it.
9Remove the banjo bolts, and disconnect
the hydraulic pressure line and the return line
from the box (see illustration). Plug the ends
of the lines to prevent fluid loss and
contamination. Discard the sealing washers -
new ones should be used when reassembling.
10Remove the steering box retaining bolts
(see illustrations)and remove the steering
box.
11If it’s necessary to detach the Pitman arm
from the box sector shaft (to have the box
serviced or to switch the arm to a new orrebuilt unit), make a match mark across the
two for correct reassembly. Remove the
Pitman arm retaining nut and washer. Use a
puller to withdraw the arm if necessary.
Refitting
12Refit the Pitman arm by aligning the
match marks made during removal, then
tighten the nut to the torque listed in this
Chapter’s Specifications.
13When fitted the Pitman arm must not have
any measurable endfloat within 100° from the
neutral position. If play exists, have the
following parts checked:
a) Sector shaft and bearings (for wear)
b) Thrust washer and adjuster bolt head (for
wear)
c) Ball nut and worm shaft (for wear)
14Refit the steering box. Align the mark on
the pinion gear shaft with the mark on the
universal joint shaft, and tighten the steering
box bolts to the torque listed in this Chapter’s
Specifications.
15The remainder of refitting is the reverse of
removal. Be sure to use new self-locking nuts
on the universal joint shaft, the centre track
rod, the steering box and the crossmember.
Also, use new sealing washers on the
hydraulic line fittings.
16Refer to Chapter 1 and fill the powersteering reservoir with the recommended
fluid, then bleed the system as described in
Section 23. Check for leakage from the lines
and connections.22 Power steering pump-

2On 5-Series E28 (“old-shape”) models,
discharge the hydraulic system by depressing
the brake pedal about 20 times before
loosening the hydraulic line fittings.
3Disconnect the fluid return hose, and drain
the power steering fluid from the reservoir into
a clean container. Disconnect the pressure
line from the pump.
4If you need to remove the pulley from the
pump, push on the power steering pump
drivebelt by hand to increase the tension, and
unscrew the pulley nuts or bolts.
5Loosen the power steering pump drivebelt
tensioner bolt, and remove the drivebelt (see
Chapter 1).
6Remove the mounting bolts (see

REF•2MOT Test Checks
Seat belts and seats
Note: The following checks are applicable to
all seat belts, front and rear.
MExamine the webbing of all the belts
(including rear belts if fitted) for cuts, serious
fraying or deterioration. Fasten and unfasten
each belt to check the buckles. If applicable,
check the retracting mechanism. Check the
security of all seat belt mountings accessible
from inside the vehicle.
MThe front seats themselves must be
securely attached and the backrests must
lock in the upright position.
Doors
MBoth front doors must be able to be opened
and closed from outside and inside, and must
latch securely when closed.
Vehicle identification
MNumber plates must be in good condition,
secure and legible, with letters and numbers
correctly spaced – spacing at (A) should be
twice that at (B).
MThe VIN plate and/or homologation plate
must be legible.
Electrical equipment
MSwitch on the ignition and check the
operation of the horn.
MCheck the windscreen washers and wipers,
examining the wiper blades; renew damaged
or perished blades. Also check the operation
of the stop-lights.
MCheck the operation of the sidelights and
number plate lights. The lenses and reflectors
must be secure, clean and undamaged.
MCheck the operation and alignment of the
headlights. The headlight reflectors must not
be tarnished and the lenses must be
undamaged.
MSwitch on the ignition and check the
operation of the direction indicators (including
the instrument panel tell-tale) and the hazard
warning lights. Operation of the sidelights and
stop-lights must not affect the indicators - if it
does, the cause is usually a bad earth at the
rear light cluster.
MCheck the operation of the rear foglight(s),
including the warning light on the instrument
panel or in the switch.
Footbrake
MExamine the master cylinder, brake pipes
and servo unit for leaks, loose mountings,
corrosion or other damage.
MThe fluid reservoir must be secure and the
fluid level must be between the upper (A) and
lower (B) markings.MInspect both front brake flexible hoses for
cracks or deterioration of the rubber. Turn the
steering from lock to lock, and ensure that the
hoses do not contact the wheel, tyre, or any
part of the steering or suspension mechanism.
With the brake pedal firmly depressed, check
the hoses for bulges or leaks under pressure.
Steering and suspension
MHave your assistant turn the steering wheel
from side to side slightly, up to the point where
the steering gear just begins to transmit this
movement to the roadwheels. Check for
excessive free play between the steering
wheel and the steering gear, indicating wear or
insecurity of the steering column joints, the
column-to-steering gear coupling, or the
steering gear itself.
MHave your assistant turn the steering wheel
more vigorously in each direction, so that the
roadwheels just begin to turn. As this is done,
examine all the steering joints, linkages,
fittings and attachments. Renew any
component that shows signs of wear or
damage. On vehicles with power steering,
check the security and condition of the
steering pump, drivebelt and hoses.
MCheck that the vehicle is standing level,
and at approximately the correct ride height.
Shock absorbers
MDepress each corner of the vehicle in turn,
then release it. The vehicle should rise and
then settle in its normal position. If the vehicle
continues to rise and fall, the shock absorber
is defective. A shock absorber which has
seized will also cause the vehicle to fail.

REF•8General Repair Procedures
Whenever servicing, repair or overhaul work
is carried out on the car or its components,
observe the following procedures and
instructions. This will assist in carrying out the
operation efficiently and to a professional
standard of workmanship.
Joint mating faces and gaskets
When separating components at their
mating faces, never insert screwdrivers or
similar implements into the joint between the
faces in order to prise them apart. This can
cause severe damage which results in oil
leaks, coolant leaks, etc upon reassembly.
Separation is usually achieved by tapping
along the joint with a soft-faced hammer in
order to break the seal. However, note that
this method may not be suitable where
dowels are used for component location.
Where a gasket is used between the mating
faces of two components, a new one must be
fitted on reassembly; fit it dry unless otherwise
stated in the repair procedure. Make sure that
the mating faces are clean and dry, with all
traces of old gasket removed. When cleaning a
joint face, use a tool which is unlikely to score
or damage the face, and remove any burrs or
nicks with an oilstone or fine file.
Make sure that tapped holes are cleaned
with a pipe cleaner, and keep them free of
jointing compound, if this is being used,
unless specifically instructed otherwise.
Ensure that all orifices, channels or pipes
are clear, and blow through them, preferably
using compressed air.
Oil seals
Oil seals can be removed by levering them
out with a wide flat-bladed screwdriver or
similar implement. Alternatively, a number of
self-tapping screws may be screwed into the
seal, and these used as a purchase for pliers or
some similar device in order to pull the seal free.
Whenever an oil seal is removed from its
working location, either individually or as part
of an assembly, it should be renewed.
The very fine sealing lip of the seal is easily
damaged, and will not seal if the surface it
contacts is not completely clean and free from
scratches, nicks or grooves. If the original
sealing surface of the component cannot be
restored, and the manufacturer has not made
provision for slight relocation of the seal
relative to the sealing surface, the component
should be renewed.
Protect the lips of the seal from any surface
which may damage them in the course of
fitting. Use tape or a conical sleeve where
possible. Lubricate the seal lips with oil before
fitting and, on dual-lipped seals, fill the space
between the lips with grease.
Unless otherwise stated, oil seals must be
fitted with their sealing lips toward the
lubricant to be sealed.
Use a tubular drift or block of wood of the
appropriate size to install the seal and, if the
seal housing is shouldered, drive the seal
down to the shoulder. If the seal housing isunshouldered, the seal should be fitted with
its face flush with the housing top face (unless
otherwise instructed).
Screw threads and fastenings
Seized nuts, bolts and screws are quite a
common occurrence where corrosion has set
in, and the use of penetrating oil or releasing
fluid will often overcome this problem if the
offending item is soaked for a while before
attempting to release it. The use of an impact
driver may also provide a means of releasing
such stubborn fastening devices, when used
in conjunction with the appropriate
screwdriver bit or socket. If none of these
methods works, it may be necessary to resort
to the careful application of heat, or the use of
a hacksaw or nut splitter device.
Studs are usually removed by locking two
nuts together on the threaded part, and then
using a spanner on the lower nut to unscrew
the stud. Studs or bolts which have broken off
below the surface of the component in which
they are mounted can sometimes be removed
using a stud extractor. Always ensure that a
blind tapped hole is completely free from oil,
grease, water or other fluid before installing
the bolt or stud. Failure to do this could cause
the housing to crack due to the hydraulic
action of the bolt or stud as it is screwed in.
When tightening a castellated nut to accept
a split pin, tighten the nut to the specified
torque, where applicable, and then tighten
further to the next split pin hole. Never slacken
the nut to align the split pin hole, unless stated
in the repair procedure.
When checking or retightening a nut or bolt
to a specified torque setting, slacken the nut
or bolt by a quarter of a turn, and then
retighten to the specified setting. However,
this should not be attempted where angular
tightening has been used.
For some screw fastenings, notably
cylinder head bolts or nuts, torque wrench
settings are no longer specified for the latter
stages of tightening, “angle-tightening” being
called up instead. Typically, a fairly low torque
wrench setting will be applied to the
bolts/nuts in the correct sequence, followed
by one or more stages of tightening through
specified angles.
Locknuts, locktabs and washers
Any fastening which will rotate against a
component or housing during tightening
should always have a washer between it and
the relevant component or housing.
Spring or split washers should always be
renewed when they are used to lock a critical
component such as a big-end bearing
retaining bolt or nut. Locktabs which are
folded over to retain a nut or bolt should
always be renewed.
Self-locking nuts can be re-used in non-
critical areas, providing resistance can be felt
when the locking portion passes over the bolt
or stud thread. However, it should be noted
that self-locking stiffnuts tend to lose theireffectiveness after long periods of use, and
should then be renewed as a matter of course.
Split pins must always be replaced with
new ones of the correct size for the hole.
When thread-locking compound is found
on the threads of a fastener which is to be re-
used, it should be cleaned off with a wire
brush and solvent, and fresh compound
applied on reassembly.
Special tools
Some repair procedures in this manual
entail the use of special tools such as a press,
two or three-legged pullers, spring com-
pressors, etc. Wherever possible, suitable
readily-available alternatives to the manu-
facturer’s special tools are described, and are
shown in use. In some instances, where no
alternative is possible, it has been necessary
to resort to the use of a manufacturer’s tool,
and this has been done for reasons of safety
as well as the efficient completion of the repair
operation. Unless you are highly-skilled and
have a thorough understanding of the
procedures described, never attempt to
bypass the use of any special tool when the
procedure described specifies its use. Not
only is there a very great risk of personal
injury, but expensive damage could be
caused to the components involved.
Environmental considerations
When disposing of used engine oil, brake
fluid, antifreeze, etc, give due consideration to
any detrimental environmental effects. Do not,
for instance, pour any of the above liquids
down drains into the general sewage system,
or onto the ground to soak away. Many local
council refuse tips provide a facility for waste
oil disposal, as do some garages. If none of
these facilities are available, consult your local
Environmental Health Department, or the
National Rivers Authority, for further advice.
With the universal tightening-up of legis-
lation regarding the emission of environmen-
tally-harmful substances from motor vehicles,
most vehicles have tamperproof devices fitted
to the main adjustment points of the fuel
system. These devices are primarily designed
to prevent unqualified persons from adjusting
the fuel/air mixture, with the chance of a
consequent increase in toxic emissions. If
such devices are found during servicing or
overhaul, they should, wherever possible, be
renewed or refitted in accordance with the
manufacturer’s requirements or current
legislation.
Note: It is
antisocial and
illegal to dump
oil down the
drain. To find
the location of
your local oil
recycling
bank, call this
number free.
