Differential Assembly: Assembly
WARNING: This page is about a different car, the 2008 Infiniti EX35. However, it is still accessible from the selected car via links, so may be relevant.
- Install side gear thrust washers with the same thickness as the ones installed prior to disassembly or reinstall the old ones on the side gears.
- Install side gears and thrust washers into differential case.CAUTION:
- Never reuse circular clip.
- Make sure that the circular clip is installed to side gear (side retainer side).
- Align 2 pinion mate gears in diagonally opposite positions, then rotate and install them into differential case after installing thrust washer to pinion mate gear.
- Align the lock pin holes on differential case with shaft, and install pinion mate shaft.
- Measure side gear end play. If necessary, select the appropriate side gear thrust washers.
- Place differential case straight up so that side gear to be measured comes upward.
- Using feeler gauge, measure the clearance between side gear back and differential case at 3 different points, while rotating side gear. Average the 3 readings, and then measure the clearance of the other side as well.
Standard
Side gear back clearance: Refer to DIFFERENTIAL SIDE GEAR CLEARANCE .
CAUTION: To prevent side gear from tilting, insert feeler gauges with the same thickness from both sides. - If the back clearance is outside the specification, use a thicker/thinner side gear thrust washer to adjust.
When the back clearance is large: Use a thicker thrust washer.
When the back clearance is small: Use a thinner thrust washer.
CAUTION: Select a side gear thrust washer for right and left individually. - Drive a lock pin into pinion mate shaft, using a punch. Make sure lock pin is flush with differential case.CAUTION: Never reuse lock pin.
- Align the matching mark of drive gear with the mark of differential case, then place drive gear.
- Apply thread locking sealant into the thread hole of drive gear.
- Use Genuine Medium Strength Thread Locking Sealant or equivalent. Refer to RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS .
CAUTION: Drive gear back and threaded holes must be cleaned and degreased sufficiently. - Install drive gear on the mounting bolts.CAUTION: Tighten bolts in a crisscross fashion.
- Press side bearing inner races to differential case, using the drift and the base.
A: Drift [SST: ST33230000 (J-25805-01)]
B: Base [SST: ST33061000 (J-8107-2)]
CAUTION: Never reuse side bearing inner race. - Press-fit side bearing outer race into side retainer with the drift and the drift bar.
A: Drift bar [SST: ST30611000 (J-25742-1)]
B: Drift [SST: KV31103000 (J-38982)]
CAUTION:- At first, using a hammer, tap bearing outer race until it becomes flat to side retainer.
- Never reuse side bearing outer race.
- Press-fit side bearing outer race into gear carrier with the drift and the drift bar.
A: Drift bar [SST: ST30611000 (J-25742-1)]
B: Drift [SST: KV31103000 (J-38982)]
CAUTION:- At first, using a hammer, tap bearing outer race until it becomes flat to gear carrier.
- Never reuse side bearing outer race.
- Place the differential case assembly into gear carrier.
- Measure side bearing preload. If necessary, select the appropriate side bearing adjusting shim. Refer to ADJUSTMENT .
- Install selected side bearing adjusting shim (1). Refer to ADJUSTMENT .
- Apply multi-purpose grease to O-ring (2), and install it to side retainer.CAUTION: Never reuse O-ring.
- Install side retainer assembly to gear carrier.
- Install side retainer mounting bolts.
- Using the drift (A) [SST: ST33400001 (J-26082)], press-fit side oil seal so that its surface comes face-to-face with the end surface of the side retainer.CAUTION:
- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of oil seal.
- Using the drift (A) [SST: KV38102100 (J-25803-01)], press-fit side oil seal so that its surface comes face-to-face with the end surface of gear carrier.CAUTION:
- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of oil seal.
- Apply multi-purpose grease to O-ring, and install it to gear carrier.CAUTION: Never reuse O-ring.
- Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and total preload torque. Refer to ADJUSTMENT
.
Recheck above items. Readjust as described above, if necessary.
- Apply sealant (A) to mating surface of carrier cover.
- Use Genuine Silicone RTV or equivalent. Refer to RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS .
CAUTION: Remove old sealant adhering to mounting surfaces. Also remove any moisture, oil, or foreign material adhering to application and mounting surfaces. - Install carrier cover on gear carrier and tighten mounting bolts.
- Set breather connector angle (A) as shown in the figure.
