NOTE: It is not necessary to use sealing agent between the housings for this procedure.
3.
Rotate the differential assembly in both directions to seat the carrier bearings.
4.
At normal room temperature, measure the starting torque of the differential assembly by rotating it in both directions using the preload inspection tool, a torque wrench (A), and a socket (B).
5.
If the carrier bearing preload is not within the standard, select an 81 mm shim that will provide the correct preload:
Compare the bearing preload you got on the first try with the specified preload of 3.5?4.5 N·m (35?46 kgf·cm, 30?40 lbf·in).
If the preload you measure was less than specified, subtract it from the specified preload.
If the preload you measure was more than specified, subtract the specified preload from the preload you measure.
Standard:
3.5?4.5 N·m (35?46 kgf·cm, 30?40 lbf·in)
6.
Subtract the appropriate thrust shim thickness from the middle of the standard preload: 4.0 N·m (41 kgf·cm, 36 lbf·in).
NOTE:
Each shim size up or down from standard makes about 0.3?0.4 N·m (3?4 kgf·cm, 2.6?3.5 lbf·in) difference in preload.
Assemble only one 81 mm shim. Do not install two or more 81 mm shim combined.
Example 1 (measured preload was less than the standard):
Measured preload: 2.1 N·m (21 kgf·cm, 18 lbf·in) with a 2.50 mm (0.0984 in) thrust shim:
Standard
4.0 N·m (41 kgf·cm, 36 lbf·in)
?Measurement
2.1 N·m (21 kgf·cm, 18 lbf·in)
1.9 N·m (20 kgf·cm, 18 lbf·in) less
The subtracted preload was 1.9 N·m (20 kgf·cm, 18 lbf·in) less than the standard, so you need a shim five sizes thicker than in measured (try the 2.65 mm (0.1043 in) 81 mm shim, and recheck).
Example 2 (measured preload was more than the standard):
Measured preload: 4.8 N·m (49 kgf·cm, 43 lbf·in) with a 2.50 mm (0.0984 in) thrust shim:
Standard
4.8 N·m (49 kgf·cm, 43 lbf·in)
?Measurement
4.0 N·m (41 kgf·cm, 36 lbf·in)
0.8 N·m (8 kgf·cm, 7 lbf·in) more
The subtracted preload was 0.8 N·m (8 kgf·cm, 7 lbf·in) more than the standard, so you need a shim two sizes thinner than in measured (try the 2.44 mm (0.0961 in) 81 mm shim, and recheck).

7.
Replace the 81 mm shim to appropriate one.
8.
With the appropriate size 81 mm shim installed in the transmission housing, check the initial preload again to verify the preload is within the standard.
