REMOVAL & INSTALLATION
The following procedure only pertains to axle shafts on vehicles with multi-link rear suspensions.
Because of the nature of the multi-link suspension, component position and bolt tightening values (torque) are critical to ride quality and rear wheel alignment. When installing components, exact location must be achieved-close doesn't count. Tightening specifications must be followed exactly or component function will be impaired.
- Disconnect the negative battery cable.
- Raise and support the vehicle safely. Do not allow the rear lifting device to interfere with the support arms.
- Remove the wheels.
- Remove the brake caliper mounting bolts and use a piece of wire to hang the caliper out of the way.
- Mark the position of the brake disc relative to its small locating pin, then remove the disc.
- Remove the brake shoes.
- Disconnect and remove the parking brake cable from the wheel bearing housing.
- Remove the retaining bolt for the support arm at the housing. Tap the support arm loose.
- Remove the nut and bolt holding the lower link arm to the housing.
- Remove the retaining bolt for the track rod (Panhard rod) at the bearing housing and use a small claw-type puller to remove the track rod.
- Loosen and remove the large nut holding the end of the driveshaft within the bearing housing.
- Remove the retaining nut for the upper link at the bearing housing. The wheel bearing housing can now be removed as a unit.
There are shims between the bearing housing and the upper link arm. Collect them when the housing is removed.
- Mount the housing assembly in a vise.
- Place a counterhold tool (5340 or equivalent) between the hub and bearing housing.
- Press out the hub with a proper sized drift.
- Remove the circlip retaining the bearing in the wheel bearing housing.
- Press the bearing out of the wheel bearing housing, using a counterhold tool (5341 or equivalent) and a suitable drift. Apply the drift to the inner ring.
- Use a bearing puller (2722 or equivalent) and a counterhold (5310 or equivalent) to pull the inner ring off the hub.
- Press in the new bearing using the drift and counterhold. Install the circlip.
- Using a counterhold below the inner ring, press the hub into place.
- Install the wheel bearing housing onto the driveshaft and install the driveshaft retaining nut. Secure the nut, but don't tighten it; that will be done later.
- Install the shims between the upper link and the wheel bearing housing and then install the retaining nut at the upper link.
- Pull the wheel bearing housing outwards at the top and tighten the upper link arm nut to 85 ft. lbs. (116 Nm) This pulling out is essential to insure correct wheel alignment when completed.
- Tilt the bearing housing outwards at the bottom (as necessary) to refit the lower link arm and its retaining bolt. When in place, pull the bottom of the bearing housing inwards (towards the center of the vehicle) and tighten the link arm to 36 ft. lbs. (49 Nm) PLUS an additional 90 degrees of rotation.
- Install the support arm and its bolt. Tighten the nut to 44 ft. lbs. (60 Nm) PLUS an additional 90 degrees of rotation.
- Install the track rod (Panhard rod) and tighten to 63 ft. lbs. (86 Nm).
- Reinstall the parking brake cable at the bearing housing.
- Reinstall the brake shoes, the brake disc as marked and the brake caliper. Tighten the caliper mounting bolts to 44 ft. lbs. (60 Nm).
- Install the wheel, tightening the lugs to 60-62 ft. lbs. (82-85 Nm).
- Lower the vehicle.
- Tighten the axle nut to 103 ft. lbs. (140 Nm) PLUS 60 degrees of rotation.
