d. Place disc pack stack in vise. Use micrometer
to determine “D”, the height (thickness) of
limited slip disc stack (includes thrust washer
and compression disc). Take four readings,
one at each of four points. Average readings
to determine “D”. Figures 4.8 and 4.9.

Assembly and Installation
10. Apply Loctite 271 or Three Bond 1305 liquid
adhesive to capscrews. Install four capscrews
into case halves equally spaced and tighten to
48-64 lb-ft (64-87 N•m).
11. Install other capscrews into case halves. Tighten
the capscrews to 48-64 lb-ft (64-87 N•m).
12. Assemble Limited Slip Differential Case.
a. Follow steps 1 to 5.
b. Place flanged case half on bench.
c. Begin stacking of the disc pack with a drive disc
followed by driven friction discs. Make sure
lubrication grooves are aligned. Figure 4.7.
Maintain the following sequence:
1) Drive disc
2) Driven friction disc
3) Drive disc
4) Driven friction disc
5) Drive disc
6) Driven friction disc
7) Drive disc
8) Shims (Do not stack until measurements are
complete.)
9) Compression disc
10) Thrust washer (on side gear side)

e. Use depth gauge to determine “C”, depth of
differential case half. Take four readings.
Average readings for result. Figure 4.9.
