The strut assembly should not be disassembled by the home mechanic, but it can be removed and taken to a dealer service department or repair shop for bearing replacement. For AWD models, begin by loosening the rear driveaxle/hub nut. Next, loosen the wheel lug nuts, raise the vehicle, and securely support it on jackstands, blocking the front wheels to prevent rolling before removing the wheel. If working on an AWD model, remove the driveaxle/hub nut, followed by the brake caliper and disc. Unplug the electrical connector from the ABS wheel speed sensor for 2WD models or remove the rear wheel speed sensor for AWD models. Remove the hub and bearing mounting bolts from the back side of the knuckle, then take out the hub and bearing assembly. For AWD models, it may be necessary to tap the driveaxle through the hub splines as the hub and bearing are withdrawn; if the driveaxle sticks, use a puller to push it out. For installation, lubricate the splines of the driveaxle with multi-purpose grease if working on an AWD model, then position the hub and bearing assembly on the rear knuckle, guiding the driveaxle into the hub splines for AWD models, and install the bolts, tightening them after all four are in place. Install a new driveaxle/hub nut for AWD models, followed by the brake disc, caliper, speed sensor, and the wheel. Finally, lower the vehicle and tighten the lug nuts, ensuring to tighten the driveaxle/hub nut and stake the collar of the nut into the slot in the driveaxle for AWD models.
