REAR FINAL DRIVE
CAUTION:
Do not change the side bearing side bearing adjusters by
different amounts as it will change the side bearing preload
torque.
d. Tighten side bearing cap bolts to the specified torque.
e. Install adjuster lock plate and tighten to the specified torque.
CAUTION:
Check tooth contact and total preload torque after adjusting
side bearing adjuster. Refer to
Companion Flange Runout
1. Rotate companion flange and check for runout on the compan-
ion flange face (inner side of the bolt holes) and companion
flange inner side (socket diameter) using suitable tool. Refer to
DLN-271, "General Specification"
.
2. If the runout is outside the runout limit, follow the procedure
below to adjust.
a. Rotate the companion flange on the drive pinion by 90
°, 180°
and 270
° while checking for the position where the runout is
minimum.
b. If the runout is still outside of the runout limit after the companion
flange has been rotated on the drive pinion, possible cause
could be an assembly malfunction of drive pinion and drive pin-
ion bearing or a malfunctioning drive pinion bearing.
c.
If the runout is still outside of the runout limit after replacing the companion flange. Replace the rear final
drive assembly. Refer to
DLN-259, "Removal and Installation"

INSPECTION AFTER DISASSEMBLY
Clean the disassembled parts. Then inspect the parts for wear or damage. If wear or damage are found, follow
the measures below.
Drive Pinion and Drive Gear
• If the gear teeth do not mesh or line-up correctly, replace with new rear final drive assembly. Refer to
261, "Disassembly and Assembly"
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new rear final
drive assembly. Refer to
DLN-261, "Disassembly and Assembly"
.
