DISASSEMBLY
1. CHECK COMPANION FLANGE RUNOUT
Using a dial indicator, measure the vertical and lateral runout of
the companion flange.
Maximum runout: 0.10 mm (0.0039 in.)
If the runout exceeds the maximum, replace the companion
flange.
2. CHECK RING GEAR BACKLASH
Using SST and a dial indicator, measure the ring gear backlash.
SST 09564±32011
Backlash: 0.1 ± 0.18 mm (0.0039 ± 0.0071 in.)
HINT:
Measure at 3 or more points on the circumference of the ring
gear.
If the backlash is not within the specified value, adjust the side
bearing preload or repair as necessary.
3. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the preload using the back-
lash between the drive pinion and ring gear.
Preload (at starting):
0.6 ± 1.0 N´m (6 ± 10 kgf´cm, 5.2 ± 8.7 in.´lbf)
4. CHECK TOTAL PRELOAD
Using a torque wrench, measure the total preload with the teeth
of the drive pinion and ring gear in contact.
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.
5. REMOVE A.D.D. ACTUATOR
(a) Remove the 4 bolts.
(b) Using a hammer handle, remove the actuator.
