|---|
| Having carried out the road test, during the fault diagnosis See table S015 NOISE WHILST DRIVING, there was a creaking noise from the rear.Continue depending on the circumstances in which the noise occurs. | End of diagnosis | The noise only occurs whilst moving. | Move on to Step 1 |
| 1 | DUST COVER CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the dust cover is not rubbing against the shock absorber casing, by moving it and applying pressure and releasing it above the shock absorber casing | Move on to Step 2 | There is rubbing | Replace the end of travel buffer |
| 2 | CHECKS UNDER THE FLOOR | All OK | Problems encountered | Operation |
|---|
| Position the vehicle on a two column lift and raise it.Check that there are no pipes, handbrake cable or heat shields under the floor that are producing noise.Also check that springs on the layout brackets are not a source of noiseSee Test 4420OA CHECK THE STATE OF SPRINGS ON LAYOUT BRACKETS | Move on to Step 3 | Pipes or heat shields incorrectly fastened | Renew the correct fastening |
| Handbrake cable noisy | Lubricate the handbrake cable |
| Springs or rubber mountings damaged. | Replace the faulty components. |
| 3 | FRONT AND REAR TRACK CONTROL ARM THRUST BUSHES CHECK | All OK | Problems encountered | Operation |
|---|
| Check that there are no signs of deterioration of the bushes for the front and rear track control arms. | Move on to Step 4 | Bushes for front arms deteriorated | Replace the track control arms Op. 4420B16 REAR SUSPENSION FRONT WISHBONE (ONE)- R R |
| Bushes for rear arms deteriorated | Replace the track control armsOp. 4420B18 REAR SUSPENSION REAR WISHBONE (ONE) - R R |
| 4 | LONGITUDINAL ANCHORAGE STRUT BUSHES CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the bushes on the attachment for the anchorage strut at the stub axle are not deteriorated.Check in accordance with the testSee Test 4420OC CHECK THE STATE OF SPRINGS ON LAYOUT BRACKETSthat the bushes fastened to the bodyshell for the longitudinal anchorage struts are correctly fitted. | Move on to Step 5 | Bushes deteriorated | Anchorage strut replacement |
| Bushes incorrectly fitted | Refit correctly |
| 5 | ANTI-ROLL BAR CHECKS | All OK | Problems encountered | Operation |
|---|
| Check that there are no faults with the anti-roll bar See Test 4420CA CHECKS ON REAR STABILIZER 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 crossmember come into contact;
- condition of centre flexible mountings in the contact area with the bar;
- presence of grease in the boots for the connecting rod between the bar and the shock absorber;
- fastenings to torque between bar and crossmember;
- fastenings to torque between bar and shock absorber connecting rod.
Check that there is no seizing / excessive clearance for the connecting rod between the bar and the shock absorber through a rotary movement. | Move on to Step 6 | Torque tightenings not correct. | Restore the correct tightening. |
| Incorrect positioning of bar in relation to vehicle centre line. | Replace the anti-roll bar Op. 4420C10 REAR SUSPENSION STABILIZER BAR - R+R |
| Paint worn at the contact points (rubbing between anti-roll bar and crossmember). | Replace the anti-roll bar Op. 4420C10 REAR SUSPENSION STABILIZER BAR - R+R |
| Signs of tearing or damage to the flexible mountings. | Replace the anti-roll bar Op. 4420C10 REAR SUSPENSION STABILIZER BAR - R+R |
| Signs of seizing /excessive clearance for the connecting rod. | Replace the connecting rod Op. 4420C12 REAR SUSPENSION STABILIZER BAR JOINT - R+R ON VEHICLE |
| 6 | SPRING/SHOCK ABSORBER ASSEMBLY CHECK | All OK | Problems encountered | Operation |
|---|
| 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 Op. 4420A12 REAR SUSPENSION DAMPER (ONE), LH OR RH - FOR MCPHERSON STRUT SYSTEM - INCLUDES DISMENTLING/REBUILDING OF ASSEMBLY AT BENCH R R Also check that the positioning and the fitting of the semi-corner assembly (spring-shock absorber assembly) is correct.Check the condition of the spring lower rubber seal and the rubber coating for the upper shim.Check that there are no signs of rubbing on the suspension spring at its supports.Also check that the spring shows no signs of interference. | If the spring shows signs of abrasion, its mechanical properties could be weakened as a result of oxidation. |
| Move on to Step 7 | Semi corner units incorrectly positioned or fitted. | Restore the correct fitting/positioning of the components |
| Signs of tearing on the rubberized shims. | Replace the components making sure that they are correctly position (spring in contact with the lower plate projection). |
| Signs of interference on the spring. | Replace the shock absorber spring Op. 4420A12 REAR SUSPENSION DAMPER (ONE), LH OR RH - FOR MCPHERSON STRUT SYSTEM - INCLUDES DISMENTLING/REBUILDING OF ASSEMBLY AT BENCH R R and the lower seal if damaged |
| 7 | MC PHERSON MOVING ELEMENTS CHECK | All OK | Problems encountered | Operation |
|---|
| Following theOp. 7040B06 SIDE TRIM (ONE) LH OR RH, LOAD COMPARTMENT/LOAD PLATFORM - R.R.remove the luggage compartment interior lining side panels, check that the noise is not caused by the movement of the shock absorber buffer plate. | End of diagnosis | The buffer plate is loose. | Tighten the upper nut to torque so that the buffer plate does not move any more. |
