- Remove all alignment marks made previously and re-mark the location of
the differential adjuster nut sleeves in relation to the differential carrier assembly
case halves.
Ensure that the notches can be counted when turned.
- Install the J 8001-1 (1,
2), the J 8001-2 (3), and the J 8001-3 (4)
as shown.
Ensure that the button contacts the outer edge of the pinion yoke and that the
plunger is at a right angle to the pinion yoke.
- Move the pinion yoke back and forth through the pinion yoke's free play
while not allowing the ring gear to move.
- Record the dial indicator reading.
- To determine the actual backlash, divide the dial indicator reading by
2.
An actual dial indicator reading of 0.16 mm (0.006 in) means that
there is actually 0.08 mm (0.003 in) backlash.
Specification
The backlash between the ring gear and the drive pinion should be between 0.08-0.25 mm
(0.003-0.010 in) with a preferred specification of 0.13-0.18 mm
(0.005-0.007 in).
Important: When adjusting the backlash, observe the following:
• | Always turn the left and the right differential adjuster nut sleeves in
equal amounts. |
• | Turning the differential adjuster nut sleeves one notch will change the
backlash about 0.08 mm (0.003 in). |
- If the backlash is too small, increase the backlash by turning the right differential
adjuster nut sleeve out one notch using the
J 36599-A
, 8.25 inch axle, or the
J 36615
, 9.25 inch axle, and the left differential adjuster nut sleeve
in one notch using the
J 36599-A
until the correct backlash is obtained.
- If the backlash is too large, decrease the backlash by turning the left
differential adjuster nut sleeve out one notch using the
J 36599-A
and the right differential adjuster nut sleeve in one notch using
the
J 36599-A
, 8.25 inch
axle, or the
J 36615
, 9.25 inch
axle, until the correct backlash is obtained.
- Recheck the rotating torque of the pinion and differential assembly and
adjust, if necessary. Refer to
Differential Carrier Assembly Assemble
.
- Once the backlash and bearing preload is within specifications, remove
the alignment markings and place new alignment marks between the differential bearing
adjuster nut and the differential carrier assembly case.
- Continue the assembly of the differential carrier. Refer to
Differential Carrier Assembly Assemble
.
