Limited Slip

PREDISASSEMBLY INSPECTION

1. Inspect rotation torque of limited slip differential as follows:
a. Use side gear holding tool set Nos. MB990998 and MB990989 or equivalent.
b. If rotation torque is not 14-29 lb-ft, when a used plate is used or 3.6-29 lb-ft, when a new plate is used, disassemble carrier and correct or replace parts.

DISASSEMBLY

Disassemble differential carrier in numbered sequence shown noting the following:
1. Loosen screws of differential case halves uniformly in several steps.
2. Separate differential case halves keeping all internal components in the order in which they are removed.
3. Before differential cases are separated, check position of alignment marks.

INSPECTION

1. Check side gears, pinion gears and pinion shaft for wear or damage.
2. Check side gear spline for wear or damage.
3. Using a dial indicator, ensure amount of warpage in less than 0.0031 inch.

ASSEMBLY

Assemble differential carrier in reverse numbered sequence shown noting the following:
1. Before assembly, use the following method to adjust clearance between spring plates and differential cases and to adjust endplay of side gear when installing internal components.
a. Obtain differential case depth (A) by subtracting dimension (D) from dimension (C) then adding dimension (B) as shown. This represents distance between clutch plate contact surface when case halves are assembled.
b. Stack spring plates on each other to make two sets. Measure and record thickness of left (Ll) and right (Lr) sets.
NOTE: Select left and right sets to minimize difference in thickness.
c. Measure thickness of friction discs and friction plates. Record left (Kl) and right (Kr) measurements.
NOTE: Select left and right sets to minimize difference in thickness.
d. Obtain thickness difference (X) between right and left clutch plate sets as follows. X = (Lr + Kr) - (Ll + Kl).
e. If difference is more than 0.0020 inch, replace components as necessary.
f. Assemble pressure rings and their inner parts, friction plates and friction discs together. Measure overall width (E).
g. Obtain clearance (Y) between clutch plate set and differential case as follows. Y = A - (E + Lr + Ll).
h. If clearance (Y) is not 0.0024-0.0098 inch change friction discs.
2. Place each part in differential case as shown.
3. After assembly, inspect rotation torque, as outlined above.
