FAULT DIAGNOSIS

Symptom :-

Steering excessively light/sensitive. Excessive
freeplay at steering wheel.

1. Are steering box adjustments correct?

NO -

See Adjustment, Power Steering Box

WARNING: Adjustments of steering box
should not be required while in warranty
period. If box is within warranty, it must be

returned to manufacturer. No attempt must be
made to introduce backlash.

bushes Check condition of ball joints and
the lower steering column shaft universal
joints for wear.

See Repair, Lower

Steering Shaft and Universal Joints

Symptom :-

Steering vibration, road wheel shimmy - wobble.

Vibration through the steering linkage powerful
enough to induce high frequency oscillation of the
steering wheel, is generally caused by out of balance
road wheels. However there are a number of other
possible causes of this symptom which if severe, may
be described as shimmy or wobble. Regardless of the
terminology used by the owner/driver to describe the
symptoms, the following diagnostic checks should be
carried out in the order presented.

1. Check the tyres and balance of the road wheels.

See GENERAL SPECIFICATION DATA,
Information, Wheels and Tyres See
WHEELS AND TYRES, Fault diagnosis, Fault
- Symptoms See WHEELS AND TYRES,
Repair, Wheel Balancing

2. Check the steering hydraulic damper function.

See Steering Damper

3. Check steering column universal joints for wear

and correct alignment.

See Repair, Lower

Steering Shaft and Universal Joints

4. Check steering linkage ball joints for wear,

correct alignment and security, including steering
box and tie rod.

See Steering Linkage Inspect

5. Check all front suspension rubbers for wear.

Check all fixing torques, including radius arm
bushes, panhard rod and anti-roll [sway] bar.
See FRONT SUSPENSION, Repair, Panhard
