A/T : Assembly

Install circular clip to side gear.
CAUTION: Never damage side gear.
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:
- Make sure that the circular clip is installed to side gears.
- Never reuse circular clip.
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.

2. 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.
3. 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.

Install drive gear on the mounting bolts.
CAUTION:
- Align the matching marks of differential case and drive gear.
- Tighten bolts in a crisscross fashion.
- After tightening the bolts to the specified torque, tighten the bolts additionally by turning the bolts 31 to 36 degrees.

Using the drift [SST: KV38100200 (J-26233)], drive side oil seals until it becomes flush with the case end.
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.
Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and total preload torque. Refer to "A/T : ADJUSTMENT ".

Recheck above items. Readjust the above description, if necessary.
Apply sealant to mating surface of rear 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 rear cover on gear carrier and tighten mounting bolts.

Install side flange with the following procedure.
1. Attach the protector [SST: KV38107900 (J-39352)] to side oil seal.
2. After the side flanges is inserted and the serrated part of side gear has engaged the serrated part of flange, remove the protector.

3. Put a suitable drift on the center of side flange, then drive it until sound changes.
  NOTE: When installation is completed, driving sound of the side flange turns into a sound that seems to affect the whole final drive.
4. Confirm that the dimension of the side flanges (1) installation measurement (A) in the figure comes into the following.
  Standard
  
  A : 326 - 328 mm (12.83 - 12.91 in)
