Editing Z31/crossmemberbushings php (section)

== Procedure ==

* Jack the car up and secure on jack stands.
* Pull the wheels off the rear.
* Place a floor jack under the differential housing to support it.
* Remove the two nuts securing the differential mount to the rear housing.
* Remove the two bolts and two nuts holding the differential mount to the body. The mount should now be free.
* Replace the old mount with the new one and tighten:
* Mount-to-body bolts:
'''22–29 ft-lbs''' - Mount-to-body nuts:
'''43–58 ft-lbs''' - Mount-to-differential carrier nuts:
'''43–58 ft-lbs'''

* Mount-to-body bolts:
* Remove the rear cross member by disconnecting the rear control arms. This is the hardest part.
* Remove the rear sway bar (4 bolts). If bushings are worn, replace them now.
* Disconnect the emergency brake cables from the calipers and main cable.
* Remove the rear control arms from the cross member:
* Each side has one regular bolt/nut and one eccentric bolt/nut.
* Mark the eccentric bolt position with a paint pen before removal for alignment.
* Torque spec:
'''72–87 ft-lbs'''

* Support the differential and remove the 4 bolts/nuts holding it to the cross member.
* Remove the 2 nuts holding the cross member to the body (torque spec:
'''58–80 ft-lbs'''). - Remove the 4 nuts holding the cross member stays. The cross member can now be removed.
-

* Press out old bushings and install new ones.

This is what they usually look like when removed.

* Use a cold chisel to punch out the metal sleeve of the bushing.

* Clean everything thoroughly.

'''Assembly is reverse of disassembly.'''
