The procedures below are applicable to the FWD automobiles only. Some special tools are needed, and indeed, the car of the 1981-85 GLC (except Wagon), so it is advisable to ensure that they are available before beginning work since it might be more cost-saving to have some job done professionally. Wipe the hub with a rag, then take away the disc brake rotor, followed by an outer bearing inner race, removed using a bearing remover and the hub should be firmly fixed. Take off the outer race with a brass drift and hammer, rinse the parts, and look at the knuckle to see whether it is damaged. In case the dust cover requires replacing, use a hammer and pipe to tap it in a good position. Install the bearing outer race into the knuckle, adjust the preload of the bearing with a spacer selection, and make adjustments of the spacer thickness to compliance. Oil the new outer oil seal with grease, then place it in, and the inner and fill in the required places with lithium grease. Install the knuckle wheel hub with a press fitting and then connect the knuckle back to the suspension with a recommended amount of torque to each component being fitted making sure to stake the driveshaft locknut. On the 323, 1983-89 626, first loosen the lug nuts, lift the car and take off the tire. Take the screw holding the hub center and loosen the tie rod end off of the steering knuckle. Unhook the brake line clip and take out the caliper assembly holding it in place. Unscrew the lower
Ball Joint and take out the strut mounting bolts. A wheel hub puller will be required to remove the hub and in isolated cases, grind part of the bearing inner race so that the hub can be removed easily. Check the knuckle, change the dust cover when necessary and make sure that the oil seal fits in place. Apply new bearing with press, and fit up inner and outer races, greasing them. Install the grease seals, reassemble the knuckle and the hub in that order with new axle locknuts and cotter pins, and measure and readjust the preload as necessary with the correct torque specifications.
