184000583 - S19 FORECARRIAGE TRANSVERSE VIBRATIONS
Whilst driving, especially on unmade roads, there are transverse vibrations at the front section. This diagnosis can only be made after See table S15 VEHICLE RUNNING NOISECarry out the latter first.| Results of the tests | ||||

|---|---|---|---|---|
| Having carried out the road test, during the See table S15 VEHICLE RUNNING NOISEtransverse vibrations are felt from the front end. Continue depending on the circumstances in which the vibration occurs | End of diagnosis | The vibration is noticeable during take off | Move on to Step 4 | |
| 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:
| Move on to Step 2 | Incorrect matching | Replace the constant velocity joint and the driveshaft Op. 2710A10 DRIVE SHAFT WITH JOINTS (ONE), L/H OR R/H - R + R | |
| Sealing ring missing | Replace the constant velocity joint and the driveshaft Op. 2710A10 DRIVE SHAFT 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 | Replace the constant velocity joint Op. 2710A20 WHEEL END CONSTANT VELOCITY JOINT (ONE), L/H OR R/H - R + R WITH DRIVE SHAFT REMOVED - INCLUDES BOOT REPLACEMENTand 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 joint | Replace the constant velocity joint Op. 2710A20 WHEEL END CONSTANT VELOCITY JOINT (ONE), L/H OR R/H - R + R WITH DRIVE SHAFT REMOVED - INCLUDES BOOT REPLACEMENTand carry out the correct greasing | |
| 4 | WHEEL SIDE JOINT TIGHTENING CHECK | All OK | Problems encountered | Operation |
| Remove the wheel Op. 4450B02 LEFT FRONT WHEEL R RCheck 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 | |
| 5 | 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, clutch, gearbox, differential, suspension). Search for the cause in one of these systems, following the appropriate diagnostic procedures |
