Check the underbody on a lift as a precaution in order to be able to locate the fault since the various mechanical components are connected and some noises may be deceptive.

Then check that the tyres are not worn irregularly

1. Internal or external tyre wear

2. Shiny parts due to rubbing

3. Slack components

4. Gaiters broken as a result of clearance or seizing

5. Deformed components.

1. Check the front geometry

Op. 4450A10 FRONT WHEEL GEOMETRY - CHECK USING OPTICAL EQUIPMENT - INCLUDES ADJUSTMENT IF NECESSARY

If necessary, replace the tyres

2. Replace the components that show signs of rubbing.

3. Restore correct fastenings.

4. Replace the steering box gaiters

Op. 4110D20 STEERING ELECTRICAL CONTROL DEVICE - R R

5. Replace the deformed parts.

1. Vibrations coming from the area of the shock absorber due to the spring

2. Vibrations coming from the area of the shock absorber due to the support.

1. Fit a rubber tube on the spring.

2. Engage or replace the components involved

Check that no noise is produced when the vehicle is moved with the wheels turned completely to the left and to the right.

Carry out the manoeuvre, accelerating and braking in order to subject the various bearings and joints to pressure

1. There is a grinding noise

2. There is a sharp bang

3. Noise from wheel area

4. There is a rotary noise

5. There is a noise in the area of the brakes.

1. Replace the wheel side constant velocity joint

2. Fasten the joint to the hub

3. Fasten the rim

4. Overhaul the differential unit

5. Replace the brake pad clips.

Carry out a road test to check that there is no noise at low speed on a good road surface.

Check whether there are variations in the noise by steering gently to load the hub bearings.

1. Rolling noise

2. There is rubbing between the stem and half-axle

3. Variations in the noise when steering.

1. Carry out the test again with tyres of a different make. If the noise decreases a lot, change the tyres.

2. Lubricate the affected parts

3. Replace the hub bearings

Op. 4450C34 ONE FRONT WHEEL HUB BEARING, LEFT OR RIGHT - REPLACE WITH STEERING KNUCKLE REMOVED

1. Noise from the gearbox area.

2. Noise from the side member area.

3. Noise from the crossmember.

1. Check the three-lobe joints and replace them if necessary

2. Check the power unit supports. Restore correct fastenings

replace them if necessary.

3. Fasten the crossmember.

1. Noise at the hubs 2. Noise from the steering area

3. There is a rubber squeaking

4. There is a plastic knocking

5. There is a drumming noise from one of the front shock absorbers: oil leak

6. There is a drumming noise from one of the rear shock absorbers: oil leak

7. There is a creaking noise.

1. Replace the ball joints.

2. Replace the steering box

Op. 4110D20 STEERING ELECTRICAL CONTROL DEVICE - R R

3. Check or, if necessary, replace the anti-roll bar mountings

4. Position the dust cover for the shock absorber

5. Replace the shock absorber

Op. 4410A12 FRONT SUSPENSION DAMPER (ONE), LH OR RH - FOR MCPHERSON STRUT SYSTEM - INCLUDES DISMANTLING/REASSEMBLY OF ASSEMBLY AT BENCH - R.R

6. Replace the shock absorber

Op. 4420A30 REAR SUSPENSION SHOCK ABSORBER (ONE), LEFT OR RIGHT - R.R. - CHECK WHEEL GEOMETRY SEPARATELY

7. Repair the cracks in the panels and/or unsoldered points

1. Noise from one of the front shock absorbers

2. Noise from one of the rear shock absorbers

3. Noise from one of the arms.

1. Fasten or, if necessary, replace the shock absorber

Op. 4410A12 FRONT SUSPENSION DAMPER (ONE), LH OR RH - FOR MCPHERSON STRUT SYSTEM - INCLUDES DISMANTLING/REASSEMBLY OF ASSEMBLY AT BENCH - R.R

2. Fasten or, if necessary, replace the shock absorber

3. Fasten or, if necessary, replace the arm

Op. 4410B40 LOWER TRACK CONTROL ARM (WITH BALLJOINT) FOR LEFT OR RIGHT FRONT SUSPENSION (ONE) - R+R - CHECK WHEEL GEOMETRY SEPARATELY

1. There are vibrations from the area of the front wheel: bearings with insufficient loading at the hub

2. There are vibrations from the area of the rear wheel: bearings with insufficient loading at the hub.

1. Replace the front hub
