FAULT DIAGNOSIS STIFF STEERING CHECKLIST
NOTE: Having completed visual checks
and steering assessment and confirmed
that vehicle steering load is incorrect carry
out the following procedure in order shown.
Steering wheel 'torque to turn' loads
1.Raise vehicle so both front wheels free.
2.With engine off, centralise steering wheel, and
remove steering wheel decal. Using torque
wrench on column nut, check torque required to
turn the steering wheel one turn in each
direction.
3.Record readings obtained in each direction.
Reading should be
4.40 Nm (3.5 lbf/ft).
NOTE: If figures are in excess of that
specified carry out steering box tie bar
reset below. If figures are as specified
See
Visual Check and Basic Adjustments
.
Steering box tie bar reset
1.Loosen the tie bar fixings one complete turn.
2.Drive vehicle carefully a short distance (within
the dealership) applying full lock in both
directions in order to settle steering components.
Drive vehicle over speed bumps and include
harsh braking if possible.
WARNING: Do not drive on public
highway.
3.Near end of operation 2. ensure vehicle is driven
in a straight line on level ground and halted.
4.Tighten panhard rod mounting arm nut to
110
Nm (81 lbf/ft).
5.Tighten the 2 fixings, tie bar to steering box, to
81 Nm (60 lbf/ft).
6.Recheck steering wheel torque to turn. If torque
reading is still greater than specified, carry out
steering shaft universal joint lubrication.Lower steering shaft universal joint lubrication
1.Check lower steering shaft is correctly phased
See Repair, Lower Steering Shaft and
Universal Joints
.
2.Lubricate universal joints with an anti-seizure
type penetrating spray. Work the joints to ensure
full penetration of the spray by driving vehicle
and steering from lock to lock.
3.If steering stiffness still persists carry out swivel
pin preload setting.
Swivel pin preload setting
1.The swivel pin preload setting must be checked
and set
See FRONT AXLE AND FINAL DRIVE,
Overhaul, Front Stub Axle, Constant Velocity
Joint and Swivel Pin Housing
.
Note that a pull load of 1.16 - 1.46 kg is required
after the axle shaft and swivel housing seal have
been removed.
Steering box adjustment
1.Check steering box adjustment
See
Adjustment, Power Steering Box
.
Steering damper check
1.Check condition of steering damper
See
Steering Damper
.
