| Having carried out the road test, during the See table S015 NOISE WHILST DRIVINGtransverse vibrations (shaking) are felt at the front end.Continue according to the circumstances in which the vibration occurs | End of diagnosis | The vibration is noticeable during take off and release. | Move on to Step 4 |
| The vibration is accompanied by noise over unmade roads. | Move on to Step 2 |
| 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 | Incorrect matching. | Replace the constant velocity joint and the driveshaft Op. 2710A10 DRIVESHAFT WITH JOINTS (ONE), L/H OR R/H - R + R |
| Sealing ring missing. | Replace the constant velocity joint and the driveshaft 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. |
| 3 | WHEEL SIDE JOINT SEIZING CHECK | All OK | Problems encountered | Operation |
|---|
| Rotate the wheel by hand and check that there is no seizing of the wheel side constant velocity joint. | Move on to Step 4 | There is seizing of the wheel side joint. | Replace the 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. |
| 4 | WHEEL SIDE JOINT TIGHTENING CHECK | All OK | Problems encountered | Operation |
|---|
| Remove the left wheel Op. 4450B02 LEFT FRONT WHEEL - R.R and/or the right one Op. 4450B04 RIGHT FRONT WHEEL - R.R Check that the constant velocity joint fastening nut is tightened and that the staking is in place. | Move on to Step 5 | Nut loosening | Replace the nut, restore the torque tightening and stake Op. 4450C32 ONE FRONT WHEEL HUB BEARING, LH OR RH - REPLACE |
| 5 | CLUTCH PLATE CHECK | All OK | Problems encountered | Operation |
|---|
| 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 | | 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. |
