Wheel installation — checking and adjustment (Opel Omega A)

1. Accurate wheel alignment significantly affects steering efficiency and prevents excessive tire wear. Before checking, make sure the vehicle is not overloaded and the tire pressure is correct.

2. The camber and caster angles are best checked at a service station using specialized equipment. The caster angle is not adjustable, unlike the camber angle of the front wheels.

3. The alignment can be checked as follows: Place the car on a level surface. Set the wheels straight ahead and roll the car back and forth for about 4 meters.

4. Using a wheel alignment template, check that the front wheels are aligned as specified in the Specifications.

5. If adjustment is necessary, loosen the clamp bolts on the side tie rods and turn the ends an equal number of threads. Both tie rods should be equal in length.

6. After adjustment, center the ball joints and tighten the bolts.
