Checking and adjustment before wheel alignment
|
If it is suspected that the alignment of the front wheels is incorrect (as indicated by the need to forcibly hold the steering wheel in a straight-ahead position, abnormal tyre wear, imprecise steering and inferior roadholding, etc.), the following procedures should be followed:
|
1.
|
Check the tyre pressures.
|
|
2.
|
Check the wheels, front-wheel bearings, suspension arm mountings and ball joints, inner track rod bushes and track rod ends. Adjust or replace any defective parts as necessary to eliminate any symptoms caused by worn components.
|
|
3.
|
Inspect the dampers and replace any that are damaged or defective, together with any worn rubber bushes.
|
|
4.
|
If the car has been involved in a collision, has run off the road or the like, any resulting damage should be repaired before checking the front-wheel alignment.
|
|
5.
|
To avoid misleading results when using wheel alignment equipment, rock the car firmly a few times before starting to check the alignment. When checking front-wheel alignment, the car should be unladen, with nobody inside it, but with a full tank of fuel and on a perfectly level surface. A variety of wheel-alignment equipment is available for mounting on the wheel rim or directly on the stub axle. For the correct use of such equipment, refer to the manufacturer's instructions.
