INSPECT UPPER AND LOWER BALL JOINTS AND DUST COVERS (a) Inspect the ball joints for excessive looseness. • Jack up the front of the vehicle and place wooden blocks with a height of 180 - 200 mm (7.09 - 7.87 in.) under the front tires. • Lower the vehicle until there is about half a load on the front coil springs. Place stands under the vehicle for safety. • Make sure the front wheels are in a straight forward position, and block them with chocks. • Using a lever, pry up the end of the upper and lower arm, and check the amount of play. Maximum ball joint vertical play: Upper 0 mm (0 in.) Lower 0.3 mm (0.012 in.) If there is play, replace the ball joint. (b) Inspect the dust cover for damage. 20.
