After carrying out a road test during diagnosis, a noise is heard from the front identifiable as a squeaking/creaking.

See table S015 NOISE WHILST DRIVING

Continue depending on the circumstances in which the noise occurs.

1. The noise is noticeable during steering, even with the vehicle stationary

2. The noise only occurs whilst moving

1. Move on to Step 1

2. Move on to Step 2

1. The buffer plate is loose

2. There is contact between the rubber part of the plate and the bodyshell

1. Tighten the upper nut to torque so that the buffer plate does not move any more

2. Place a shim no larger than 2 mm in between

Replace the end of travel buffer

1. End travel stop incorrectly inserted (correct insertion is with the largest diameter side facing up)

2. End of travel buffer deteriorated.

1. Replace the end of travel buffer

2. Replace the end of travel buffer [PR_4410A70].

Position the vehicle on a two column lift and raise it.

Check that there are no pipes or heat shields under the floor that are producing noise

1. Front bush not intact

2. Rear bush not intact

1. Replace the front bush

Op. 4410B50 BUSHES FOR L/H OR R/H FRONT SUSPENSION LOWER TRACK CONTROL ARM - REPLACE AT BENCH

2. Replace the rear bushing

Op. 4410B52 FRONT SUSPENSION LOWER TRACK CONTROL ARM REAR BUSH LEFT OR RIGHT - REPLACE AT BENCH

Check that there are no faults with the anti-roll bar

See Test 4410CA CHECKS ON FRONT ANTI-ROLL BAR

More specifically:

- Anti-roll bar correctly positioned in relation to the centre-line of the vehicle

- Paint not worn at the points where the bar and the track control arms come into contact

- Condition of flexible mounting in the contact area with the bar

- Fastenings tightened to torque between bar and crossmember

- Fastenings tightened to torque between the bar and rod and between the rod and shock absorber bracket

1. Torque tightenings not correct

2. Bar not correctly positioned

3. Paint worn at the contact points (rubbing between bar-wishbones).

4. Signs of tears/damage to flexible block

1. Restore the correct tightening.

2. Replace the anti-roll bar

Op. 4410C10 FRONT SUSPENSION ANTI-ROLL BAR - R+R - CHECK WHEEL GEOMETRY SEPARATELY

3. Replace the anti-roll bar

Op. 4410C10 FRONT SUSPENSION ANTI-ROLL BAR - R+R - CHECK WHEEL GEOMETRY SEPARATELY

4. Replace the anti-roll bar

Op. 4410C10 FRONT SUSPENSION ANTI-ROLL BAR - R+R - CHECK WHEEL GEOMETRY SEPARATELY

Check that the mountings fastening the suspension to the bodyshell (at the shock absorber turrets) do not show signs of wear on account of rubbing.

The shock absorber must be removed for this check

Also check that the positioning and the fitting of the semi-corner assembly (spring-shock absorber assembly) is correct.

Check that there are no signs of rubbing on the suspension spring at its supports. Also check that the spring shows no signs of wear

If the spring shows signs of abrasion, its mechanical properties could be weakened as a result of oxidation.

1. Positioning or fitting of semi-corner assembly not correct

2. Signs of tears/damage to shock absorber blocks/pads

3. Spring worn

4. Signs of rubbing between spring and supports

1. Restore the correct fitting/positioning of the components

2. Replace the components and ensure they are correctly positioned

3. Replace the shock absorber spring (ensure that the first coil is correctly positioned on the shock absorber plate, 4 mm at most from the contact point)

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

4. Refit correctly
