10. Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion bearing preload torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Do not
loosen drive pinion lock nut to adjust the preload torque.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
12. Install differential case assembly. Refer to RFD-33, "
Differential Assembly" .
CAUTION:
Do not install rear cover yet.
13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion flange runout. Refer to RFD-19, "
Drive Gear Runout" , RFD-20, "Tooth Contact" , RFD-21, "Backlash" ,
RFD-22, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to RFD-19, "
Total Preload Torque" .
15. Install rear cover. Refer to RFD-33, "
Differential Assembly" .

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionsNES000G0

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 when installing. Since new caulking nuts are pre-
oiled, tighten as they are.
