9. If the turning torque is outside the specification, use a thicker/ thinner side bearing adjusting shim to adjust. Refer to FFD-40,
"Side Bearing Adjusting Shim" .
10. Record the total amount of shim thickness required for the cor- rect carrier side bearing preload.
Pinion Gear Height
If the hypoid gear set has been replaced, select the pinion height adjusting washer.
1. Use the formula below to calculate pinion height adjusting washer thickness.
2. Select the proper pinion height adjusting washer. Refer to FFD-40, "
Pinion Height Adjusting Washer" .
If impossible find the desired thickness of washer, use washer with thickness closest to the calculated
value.
Pinion Bearing Preload

Assemble the drive pinion parts if they are disassembled. Refer to FFD-32, "Drive Pinion Assembly" .
1. Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1). If the turning torque is less than the specified range:
Decrease the side bearing adjusting shim thickness.
If the turning torque is greater than the specification:
Increase the side bearing adjusting shim thickness.

Washer selection equation:
T = T
0 + (t1 - t2 )
T: Correct washer thickness
T
0 : Removed washer thickness
t
1 : Old drive pinion head letter “H × 0.01”
(“H”: machined tolerance 1/100 mm × 100)
t
2 : New drive pinion head letter “H × 0.01”
(“H”: machined tolerance 1/100 mm × 100)
Example:
T = 3.21 + [(2 × 0.01) - (-1 × 0.01)] = 3.24

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
PRECAUTIONSPFP:00001
CautionNES000FK

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

Unladen conditions mean 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.

Avoid burden to front cross bar.
