| Having carried out the road test. See table S015 NOISE WHILST DRIVINGtransverse vibrations are felt from the front end.Continue according to the circumstances in which the vibration occurs | End of diagnosis. | 1. The vibration is noticeable during take off and release.3. The vibration is accompanied by noise over unmade roads. | 1. Move on to Step 4.3. Move on to Step 1. |
| 1 | WHEEL SIDE CONSTANT VELOCITY JOINT CHECK | All OK | Problems encountered | Operation |
|---|
| Raise the vehicle on a two column lift and check:- that the driveshaft-wheel side joint matching is correct;- that the seal is present. | Move on to Step 2. | 1. Incorrect matching.2. Sealing ring missing. | 1. Replace the constant velocity joint and the half-axle Op. 2710A10 DRIVESHAFT WITH JOINTS (ONE), L/H OR R/H - R + R 2. Replace the constant velocity joint and the half-axle. Op. 2710A10 DRIVESHAFT WITH JOINTS (ONE), L/H OR R/H - R + R |
| 2 | WHEEL SIDE JOINT CLEARANCE CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the clearance for the wheel side constant velocity joint is not too great. | Move on to Step 3. | Excessive clearance compared with the opposite wheel side joint. | Replace the wheel side constant velocity joint. Op. 2710A20 WHEEL SIDE CONSTANT VELOCITY JOINT (ONE), L/H OR R/H - R + R WITH DRIVESHAFT REMOVED - INCLUDES BOOT REPLACEMENT and carry out the correct greasing. |

| Check that there is no irregular wear on the surface of the clutch plate. | Move on to Step 6. | Surface of the clutch plate worn unevenly. | Replace the assembly. Op. 1810A20 CLUTCH - R + R |
| 6 | CORRECT OPERATION CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the fault is no longer present. | End of diagnosis. | The fault persists. | The fault is due to another system (engine, gearbox, differential, suspension). Search for the cause in one of these systems, following the appropriate diagnostic procedures. |
