| Having carried out the road test, during the See table S015 NOISE WHILST DRIVINGthere is transverse vibration in the front section. Continue depending on when the vibration is present. | End of diagnosis | The vibration is noticeable during take off and release. | Move on to Step 5 |
| The vibration is accompanied by noise which increases with speed. | Move on to Step 2 |
| The vibration is accompanied by noise over unmade roads. | 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 | 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 | INTERMEDIATE SHAFT BEARING CHECK | All OK | Problems encountered | Operation |
|---|
| Check the condition of the intermediate shaft bearing. | Move on to Step 3 | Bearing damaged | Replace the bearing Op. 2710A31 INTERMEDIATE DRIVESHAFT - R R |
| 3 | 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 4 | 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 REPLACEMENTand carry out the correct greasing. |
| 4 | 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 5 | There is seizing of the 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 REPLACEMENTand carry out the correct greasing. |
| 5 | WHEEL SIDE JOINT TIGHTENING CHECK | All OK | Problems encountered | Operation |
|---|
| Remove the left wheel Op. 4450B02 LEFT FRONT WHEEL - R.Rand/or the right one Op. 4450B04 RIGHT FRONT WHEEL - R.RCheck that the constant velocity joint fastening nut is tightened and that the staking is in place. | Move on to Step 6 | Nut loosening | Replace the nut, restore the torque tightening and stake Op. 4450C28 FRONT WHEEL HUB,LEFT OR RIGHT - R.R WITH WHEEL REMOVED, CHECK WHEEL GEOMETRY SEPARATELY |
| 6 | 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 7 | Surface of the clutch plate worn unevenly. | Replace the clutch plate Op. 1810A20 CLUTCH - R + R |
| 7 | CHECK ON CORRECT OPERATION | 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. |
