Start by loosening the rear wheel lug nuts and raising the rear of the vehicle on jackstands.

To remove the intermediate shaft, first remove the right-side driveaxle, then take out the intermediate shaft bracket bolts and the wheel speed sensor before pulling the intermediate shaft out of the transaxle. If necessary, replace the oil seal.

Start by loosening the rear wheel lug nuts and raising the rear of the vehicle on jackstands. Remove the rear wheels and disconnect the brake pipes from the hoses at the trailing arms, plugging the fittings to prevent dirt or fluid loss. If applicable, disconnect the ABS electrical connectors at the rear axle. Release the ends of the parking brake cables from the rear brakes and remove the coil springs. Support the rear axle with floor jacks and remove the mounting bolts securing the axle bushing brackets to the body. Carefully lower the rear axle assembly to the floor and inspect the trailing arm pivot bushings.

Proceed to remove the drive axle hub nut. Disconnect the stabilizer bar end link and the tie-rod end from the steering knuckle, and also disconnect the ABS wheel speed sensor. Separate the control arm from the steering knuckle and tap the end of the driveaxle with a soft-faced hammer to loosen it from the hub splines. If it's stuck, a puller may be required. Once the driveaxle is loosened, pull out on the steering knuckle and detach the driveaxle from the hub, suspending the outer end with a bungee cord or wire.
