Exhaust System
The exhaust system is designed to be maintenance free, al-
though regular inspection is warranted due to the harsh oper-
ating conditions. Under normal conditions, the catalytic
converter does not require replacement unless it is damaged.
New fasteners, clamps, rubber mounts and gaskets should
be used when replacing exhaust components.
A liberal appli-
cation of penetrating oil to the exhaust system nuts and bolts
in advance may make removal easier.
WARNING -
The exhaust system and catalytic converter operate at
very high temperatures. Allow components to cool before
servicing. Wear protective clothing to prevent burns.
Do not use flammable chemicals near a hot
cataiyiic
converter.
Corroded exhaust system components crumble easily
and often have exposed sharp edges. To avoid injury,
wear eye protection and heavy gloves when working
Exhaust system, removing and installing
The removal and installation procedures given here are gen-
eral procedures for all models. The removal of the exhaust
system as a complete unit is recommended. Once the com-
plete system is removed from the car, individual pipes and
mufflers can be more easily replaced.
WARNING-
Exhaust gases are colorless, odorless, and very toxic. Run
the engine only in a well-ventilated area. Immediately repair
any
leaks in the exhaust system or structural damage to the
car body that
might allow exhaust gases to enter the passen-
ger compartment.
CAUTION-
Use care not to drag or bang oxygen sensors. Oxygen sen-
sors can be easily ruined.

CV joint boots
NOTE-
When replacing a CVjoint boot, use a complete CVjoint
boot repair kit. The lit will include a new boot, clamping
bands, special lubricant, and a new inner CV joint circlip.
The lit is available from an authorized
BMW dealerparts
department.
The outer CVjoint cannot be removed from the axle
shaft
In order to replace the outer CV boot, it is necessary to re-
move the inner joint and boot first.
If the
CVjoints are worn or defective, a complete rebuilt
axle shaft is available from an authorized
BMW dealer
parts department.
- Remove appropriate axle shaft. See Drive axle, removing
and installing (sedan), or Drive axle, removing and in-
stalling (Sport Wagon).
- Working with axle shaft at bench, cut off old boot clamps and
remove boot. Clean old grease off joint and shaft. Use new
grease from CV joint boot kit.
4 Remove dust cover from CV joint and remove circlip (arrow)
retaining joint inner hub to axle shaft.

I Final Drive
4 Support inner hub with BMW special tools 26 1 110 and
press axle shaft out of joint using BMW special tool 21 2 120.
- Clean all old lubricant off shaft splines and inner joint splines.
If the CVjoint must be disassembled for cleaning and inspec-
tion, be sure to matchmark inner and outer race and interme-
diate ball cage. This allows reassembly
ofparfs in their
original positions.
NOTE-
To inspect a CVjoint, clean away the grease and loolc forgall-
ing, pitting, and other signs of wear orphysical damage. Pol-
ishedsurfaces or visible ball traclts alone are not necessarily
cause forreplacement. Discoloration due to overheating indi-
cates
laclt of lubrication.
- Slide CV joint boot onto axle shaft
- Apply LoctiteO270 or an equivalent heavy-duty loclting corn-
pound to drive axle splines. Position new CV joint on shaft so
that raised or taller side of hub is facing shaft.
WARNING-
Do not let the locking compound contact the balls in the joint.
Apply only a thin coat to cover the splines.
While supporting axle shaft with BMW special tool
33 2 130
press inner hub of CV joint onto shaft. Install a new circlip.
- Install new boot clamps.
- Use sealing gel to seal dust cover to CV joint prior to reinstal-
lation.
NOTE-
* Do not let the ball hub pivot too far in the outer ring of the
joint.
Tlie balls will fa1 out.
Before installing each small boot clamp be sure to
'burp"the
boot by flexing the CVjoint. A small screwdriver inserted be-
tween the boot and the axle shafl will help the process.

Brakes
The brake booster is mounted to the bulkhead on driver's side
of the engine compartment, directly behind the brake master
cylinder. Intake manifold vacuum acts on a large diaphragm
in the brake booster to reduce brake pedal effort.
Brake booster check valve
The checlc valve in the bralte booster vacuum line prevents
contamination from engine backfires and other sources from
entering the bralte booster.
Location of
check valve varies, depending on year and mod-
el.
