2. Temporarily install pinion height adjusting washer (1).
When hypoid gear se t has been replaced Select pinion height adjusting washer. Refer to "Pinion Gear
Height".
When hypoid gear set has been reused Temporarily install the removed pinion height adjusting washer
or same thickness washer to drive pinion.
3. Install selected pinion height adjusting washer (2) to drive pin- ion. Press pinion rear bearing inner race (1) to it, using drift.
CAUTION:
 Pay attention to the direction of pinion height adjusting
washer. (Assemble as shown in the figure.)
 Never reuse pinion rear bearing inner race.
4. Temporarily assemble removed drive pinion adjusting washer and drive pinion bearing adjusting washer or same thickness
them to drive pinion.
5. Apply gear oil to pinion rear bearing, and assemble drive pinion into gear carrier.
6. Apply gear oil to pinion front bearing, and assemble pinion front bearing inner race to drive pinion assembly.
CAUTION:
Never reuse pinion front bearing inner race.
7. Using suitable spacer (A), press the pinion front bearing inner race to drive pinion as far as drive pinion nut can be tightened.
8. Adjust pinion bearing preload. If necessary, select the appropri- ate drive pinion adjusting washer and drive pinion bearing
adjusting washer. Refer to "Pinion Bearing Preload".
9. Using the drifts, install front oil seal as shown in figure. CAUTION:

• 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 l ubricant 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 w hen installing. Since new caulking nuts are pre-oiled,
tighten as they are.
 Avoid burden to front cross bar.
