- Remove the lug nuts (x5) and the puller washers (x5) from the LH rear rotor studs, and then remove the hub puller from the rotor.
-
Install the bolt that
attaches the brake rotor to the hub.NoteReinstall the lug nut previously installed for early production vehicles.
- Install a spring compressor onto the LH rear coil spring. Line up the hooks per image and verify that the spindle goes through the body opening when the suspension is compressed.
- Position a support stand underneath the LH rear suspension.
- Remove the bolt and nut that attach the LH upper aft link to the knuckle.
- Remove the bolt and nut that attach the LH upper fore link to the knuckle.
- Remove the bolt and nut that attach the LH toe link to the knuckle.

the LH rear damper at the top mount.
- Lower the support stand to gain access for halfshaft removal.
- Separate the halfshaft from the hub assembly, and then move the halfshaft aside.
-
Position the axle remover
cable around the inner joint of the LH rear drive unit halfshaft, and then
use a cable tie to hold the axle remover cable in position.
- Hook the axle remover slide hammer on the 2 axle remover cable loops, and then use the slide hammer to remove the halfshaft from the drive unit.
Install
-
Apply approximately 1 gram
of Molykote M-77 Lubricant Paste only to the hub
mating face on the outboard side of the LH rear drive unit halfshaft.
CAUTIONDo not apply any lubricant to the halfshaft splines. If lubricant is mistakenly applied, wipe the splines clean with a shop towel.
-
Install the halfshaft into
the rear drive unit.
CAUTIONWhen installing the halfshaft to the drive unit:
- Take care not to damage or displace the oil seals.
- Make sure that the opening of the snap rings are facing towards the bottom of the drive unit.
- Carefully push the halfshaft into the drive unit until there is an audible "click" from the halfshaft stub contacting the pinion shaft.
- There will be a slight pulling sensation on the halfshaft as the halfshaft circlip locks into place.
- Pull on the inner halfshaft cup to confirm that the circlip is locked into place. If the halfshaft detaches from the drive unit then reinstall the halfshaft and then test that it is fully seated.
- Set the LH halfshaft temporarily on the lower aft link.
- Swing out the upper section of the knuckle and mate the halfshaft to the hub.
- Align the splines of the LH rear halfshaft with those of the LH rear hub, and then install the halfshaft into the hub.
-
Install only the axle nut onto the
halfshaft, and then use a ratchet and socket to manually tighten the nut to pull the
halfshaft into the hub until it seats.
NoteDo not use power tools to tighten the nut as it might strip the threads.
-
Remove the axle nut from the halfshaft,
install a new washer onto the halfshaft, and then reinstall the axle nut hand
tightened.
NoteThe axle nut is torqued in a later step.
- Use the support stand to raise the LH rear suspension.
- With an assistant, install and hand-tighten the bolt and nut that attach the LH toe link to the knuckle.
- With an assistant, install and hand-tighten the bolt and nut that attach the LH upper fore link to the knuckle.
- With an assistant, install and hand-tighten the bolt and nut that attach the LH upper aft link to the knuckle.
-
Install a new nut to attach
the rear stabilizer bar link to the rear stabilizer bar, and then mark the
nut with a paint pen.NoteCounter-hold the ball joint with a 5 mm hex wrench.
-
Install the bolts that
attach the LH rear damper at the top mount.
-
Raise the support stand to
simulate vehicle at ride height.
NoteMake sure that the support stand do not block access to adjust the spring compressor or suspension bolts.NoteUse the rear ride height torque gauge to verify that the rear suspension is set to ride height specifications and adjust the support stand or spring compressor tool , if necessary.
- Measure the distance between the bottom of the quarter panel to the center of the rear axle to make sure that the rear suspension is set to ride height: The distance should measure 378 mm.
