1CHECK ON DRIFTAll OKProblems metOperation
Test the vehicle on a straight line, on a good road surface and with no wind and check that there is no driftThe car driftsSwap over the front wheelsContinue to Step 2
2CHECK ON DRIFTAll OKProblems metOperation
Test the vehicle on a straight line, on a good road surface and with no wind and check that there is no driftThe drift has changed directionReplace the tyres Op. 4450B21Continue to Step 3
The car continues to drift in the same directionSwap over the front/rear wheels on the same sideContinue to Step 3
3CHECK WHEEL GEOMETRYAll OKProblems metOperation

Wheels braked: front hub bearing faultReplace the components involved Op.   4450C32 
Wheels braked: front hub faultReplace the components involved Op.   4450C10 
wheels braked: rear bearing or hub faultReplace the components involved Op.   4450D10 
4CHECK ON STEERING WHEEL LOADAll OKProblems metOperation
Check that during steering, there are no changes in load on the still steering wheel with wheels both on the ground and raisedContinue to Step 5A change in load on the steering wheel is observedRotate the steering column by 90° around its axis and re-align the steering wheel spokes Op. 4410A14
5CHECK ON DRIFTAll OKProblems metOperation
Test the vehicle on a straight line, on a good road surface and with no wind and check that there is no driftContinue to Step 6The vehicle still driftsReplace the differential unit Op.   2110D10 
6CHECK ON STEERING WHEEL RETURNAll OKProblems metOperation
Test the vehicle on a straight line, on a good road surface and with no wind and check that there is no drift when the steering wheel returns after a steering actionContinue to Step 7The vehicle drifts on return of the steering wheel: different caster on right and leftRestore the correct caster Op.   4450A10 
7CHECK ON CORRECT OPERATIONAll OKProblems metOperation
Check that the fault is no longer presentFault persistsSearch for the fault starting from another symptom'
