DISASSEMBLY
1. REMOVE DIFFERENTIAL CARRIER COVER
(a) Remove the 9 bolts and nut from the carrier cover.
(b) Using a brass bar and hammer, separate the cover from
carrier.
(c) Remove the breather plug from the differential carrier cov-
er.
(d) Remove the 2 bolts and oil deflector from the differential
carrier cover.
2. SET DIFFERENTIAL CARRIER TO OVERHAUL
STAND, ETC.
3. CHECK RUNOUT OF COMPANION FLANGE
Using a dial indicator, measure the vertical and lateral runout of
the companion flange.
Maximum: 0.09 mm (0.0035 in.)
If the runout is greater than the maximum, replace the compan-
ion flange.
4. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.07 mm (0.0028 in.)
If the runout is greater than the maximum, replace the ring gear
and drive pinion as a set.
5. CHECK RING GEAR BACKLASH
Using a dial indicator, while holding the drive pinion flange mea-
sure the ring gear backlash.
Backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 in.)
HINT:
Measure at 3 or more places on the circumference of the ring
gear.
If the backlash is not within the specification, adjust the back-
lash.

6. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the drive pinion preload using
the backlash of the drive pinion and ring gear.
Preload (at starting):
0.5 - 0.8 N´m (5 - 8 kgf´cm, 4.3 - 6.9 in.´lbf)
7. CHECK TOTAL PRELOAD
Using a torque wrench, measure the total preload.
Total preload (at starting):
Drive pinion preload plus
0.4 - 0.6 N´m (4 - 6 kgf´cm, 3.5 - 5.2 in.´lbf)
If necessary, disassemble and inspect the differential.
8. INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See page SA-47)
9. REMOVE SIDE GEAR SHAFT OIL SEALS
Using SST, remove the 2 side gear shaft oil seals.

(c) Remove the 4 bolts and differential tube with side gear
shaft from the differential carrier.
(d) Remove the side gear shaft from the differential tube.
11. REMOVE SIDE GEAR BEARING
Using SST and a press, remove the bearing from side gear
shaft.
