BEARINGS
Inspect
D
Bearings for smooth rotation after oiling them.
Bearing rollers for wear.
Bearing cups for wear, cracks, brinelling, and scor
ing.
Important
When replacing worn or cracked bearings and
cups, make sure to replace them in sets.
Ring gear and pinion gear for wear and replace
them as a set if worn
Important
Low mileage bearings may have small scratches
on the rollers and the bearing cups from the initial
preload. Do not replace a bearing for this reason.
SHIMS
i?
Inspect
Shim s for cracks and chips. Dam aged shim s
should be replaced with an equal size service
shim.
ASSEMBLY OF THE REAR AXLE
DIFFERENTIAL CASE ASSEMBLY
Tools Required:
J 24385 Differential Case Spreader
D-136/D-346 Master Differential Bearings
Install or Connect (Figures 2, 14, and 15)
1. Lubricate all parts with axle lubricant.
2. New side gear thrust washers (27) to the side
gears (25).
3. Side gears (25) to the differential case.
• Install the side gears on the same side as
removed.
4. Pinion gears (24) to the differential without the
thrust washers (26).
A. Install the pinion gears to the side gears so the
holes in the pinion gears are 180 degrees
apart.
B. Rotate the pinion gears into place, and verify
that the pinion gears line up with the pinion
shaft holes.
5. New pinion thrust washers (26).
• Rotate the pinion gears toward the differential
opening enough to slide in the pinion thrust
washers.
6. Pinion shaft (28).
• Align the roll pin holes in the case and shaft.
7. Roll pin (29) (figure 14).
A. Peen metal from the case over the lock pin in
two places, 180 degrees apart.
B. Make sure the mating surfaces of the differen
tial case and the ring gear are clean and free of
burrs.
8. Ring gear to the case (2).
A. Align the holes in the case with the holes in the
ring gear.
B. Press the ring gear onto the case.
NOTICE: Refer to “Notice” on page 4B5-1.
9. New ring gear bolts (23).
Tighten
A. Ring gear bolts in stages, gradually pulling the
ring gear onto the differential case.
B. Ring gear bolts in sequence to “ Specifications.”
10. Master differential bearings D-136/D-346 to the dif
ferential (figure 15).
• Refer to “ Determining Total Shim Pack Size.”
• Outboard spacers, if used, should be in place.
