(7) At the same time, measure the total preload
of drive pinion. Compared with the resistance
when differential case is not installed, if the total
preload is not within the specified range, read-
just side bearing retainer shims, increasing/re-
ducing by an even amount at a time.
Total preload:
26.95 — 53.90 N (2.75 — 5.50 kgf, 6.1 — 12.1
lb)
21) Re-check the crown gear-to-pinion backlash.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
22) Check the crown gear runout on its back sur-
face, and make sure that pinion and crown gear ro-
tate smoothly.
Limit of runout:
Less than 0.05 mm (0.0020 in)
23) Checking and adjusting tooth contact of crown
gear
(1) Apply an even coat of red lead on both sides
of three or four teeth on the crown gear. Check
the contact pattern after rotating the crown gear
several revolutions back and forth until a definite
contact pattern appears on the crown gear.
(2) When the contact pattern is incorrect, read-
just according to the instructions given in
"TOOTH CONTACT PATTERN".
NOTE:
Be sure to wipe off red lead completely after adjust-
ment is completed.
REAR DIFFERENTIAL
• Correct tooth contact
Checking item: Tooth contact pattern is slightly
shifted toward to toe side under no-load
rotation. (When loaded, contact pattern moves
toward heel)
• Face contact
Checking item: Backlash is too large.
Contact pattern
DI-00099
Corrective action: Increase thickness of drive pin-
ion height adjusting shim in order to bring drive pin-
ion close to crown gear.
