Excessive Friction Check

The procedure for checking excessive friction in the rear suspension is as follows:
1. With the aid of a helper, lift up on the rear bumper and raise the vehicle as high as possible. Slowly release the bumper and allow the vehicle to assume normal trim height.
2. Measure the distance from floor to the center of the bumper.
3. Push down on bumper, release slowly and allow vehicle to assume normal trim height.
4. Measure the distance from the floor to the center of the bumper. The difference between the two measurements should be less than 12.7 mm (1/2 inch). If the difference exceeds this limit, inspect the front and rear wheel spindle rods and struts for damage or wear.
