== Z31 Replacing Rear Wheel Bearings ==

To make a long story short, My 86 N/A right rear inner and outer bearings were toast. The "fun" part was replacing them. Don't even attempt this if you don't have access to air tools.

Part number: BE2740 — fits both non-turbo and turbo Z31s, with or without adjustable suspension.

''WARNING'' - Do this modification at your own risk. We Are not responsable for any issues of your own doing.

12mm open/box end wrench
12mm Socket and ratchet
13mm Socket
15mm Socket
17mm Socket
Bearing Packing tool
Long Pry-bar
Jack and Jack Stands
Rubber mallet
Slide Hammer with wheel puller attachment

High temperature Bearing Grease

=== Replacement Process ===

-
Jack up the car and remove the tire, brake caliper, and rotor assembly. Undo the 17mm bolt holding the spring seat stay, and the 12mm bolt holding the e-brake cable bracket. Pry down the spring seat stay to access the bolts that hold the drive axle to the companion flange.

* Undo the 12mm bolts from the drive axle to the axle flange (with nuts on the outside). Turbo models have 4 bolts, non-turbo have 6. Pry the axle out and remove it from the differential.
-
Remove the 30mm wheel bearing lock nut with a socket and impact gun. Wedge a pry bar in the wheel studs to keep it from turning. After the nut is off, use a wheel puller to remove the companion flange from the axle shaft.

-
Use the wheel puller attachment on a slide hammer on the hub side to pull the hub/stub axle from the bearings and control arm. Remove the bearings and replace with new, packed with high-temp grease. Make sure the bearings sit correctly in the race.

* Reassembly is the reverse of disassembly.

==== Rear Wheel Bearing Torque Specs ====

* Wheel bearing lock nut: 217–289 ft-lbs
* Drive axle to companion flange (Turbo): 43–51 ft-lbs
* Drive axle to companion flange (Non-Turbo): 29–36 ft-lbs
* Spring seat stay: 43–58 ft-lbs
