REAR FINAL DRIVE ASSEMBLY
Never change the total amount of washers as it will change the bearing preload.
Companion Flange Runout
1. Fit a test indicator to the inner side of companion flange (socket
diameter).
2. Rotate companion flange to check for runout.
3. If the runout value is outside t he runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion by 90 ° step, and search for the position
where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if necessary.
c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove side flange.
3. Remove rear cover mounting bolts.
4. Remove rear cover to insert the seal cutter between gear carrier and rear cover.
CAUTION:
 Be careful not to damage the mating surface.
 Never insert flat-bladed screwdriver, this way damage the
mating surface.
5. Using two 45 mm (1.77 in) spacers, mount carrier on the attach- ment.Runout limit: 0.08 mm (0.0031 in)

• When installing rubber bushings, final tightening must be carried out under unladen conditions with tires on
level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
 Unladen conditions means that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
 After servicing suspension parts, be sure to check wheel alignment.
 Caulking nuts are not reusable. Always use new ones w hen installing. Since new caulking nuts are pre-oiled,
tighten as they are.
