5. TOTAL PRELOAD
Using a spring balance, check the total preload.
Total preload:
20.7 — 54.4 N (2.1 — 5.5 kgf, 4.7 — 12.2 lb)
If the total preload is not within the specification,
adjust the side bearing retainer shim drive pinion
shaft preload.
6. COMPANION FLANGE
1) If rust or dirt is attached to the companion flange,
remove them.
2) Set a dial gauge at a companion flange surface
(mating surface of propeller shaft and companion
flange), and then measure the companion flange
runout.
Limit of runout:
0.08 mm (0.0031 in)
3) Set the gauge inside of the companion flange,
and measure the runout.
Limit of runout:
0.08 mm (0.0031 in)
Rear Differential (T-type)
4) If either runout exceeds the limit, move the
phase of companion flange and drive pinion 90°
each, and find the point where the runout is within
the limit.
5) If the runout exceeds the limit after changing the
phase, replace the companion flange and recheck
the runout.
6) If the runout exceeds the limit after replacing the
companion flange, the drive pinion may be assem-
bled incorrectly or bearing is faulty.
