Power Train Disassembly & Assembly
2. Apply a 0.125 inch (3.18 mm) diameter continuos
bead of silicone gasket material (Three bond 1216
or Loctite 5699) around the flange mounting face
of either the axle housing or the spindle. Also
apply the gasket material around the edge of all
the fastener holes on that surface.
3. Install the spindle onto the axle housing.
4. Install the brake spider onto the spindle (29).
5. Install and hand tighten some of the spindle
mounting capscrews (27) and washers (28).
6. Remove the two temporary studs.
7. Install the remaining spindle mounting capscrews
and washers. Tighten all capscrews to 310-400
lb•ft (420-542 N•m).
NOTE : Replace the camshaft bushing and grease
seals before the camshaft bracket is installed onto
the brake spider. Refer to brake section of this
manual.
8. Install the brake camshaft bracket with the O-ring
on the pilot onto the brake spider.
9. Install the four mounting capscrews and washers.
Tighten the capscrews to 85-115 lb•ft (115-156
N•m).
10. Install the brake camshaft bracket clamp around
the bracket tube and install the two capscrews
and washers that mount the clamp to the axle
housing. Tighten the capscrews to 35-50 lb•ft (47-
68 N•m).
NOTE : Refer to brake section of this manual, to
install the brake camshaft, anchor pin components,
brake shoes, brake springs, slack adjusters and
related parts.
11. Install the air chamber to bracket mounting nuts.
Tighten the nuts to 100-115 lb•ft (136-156 N•m).
12. Attach the chamber push rod yoke to the slack
adjuster. Tighten the yoke jam nut to 25-50 lb•ft
(34-68 N•m).
13. Install the brake dust shield. Tighten the
mounting capscrews and washers to 35-50 lb•ft
(47-68 N•m).
Assemble the Wheel End
1. Press the new inner and outer bearing cups (24,
19) into the wheel hub (23).
2. Position the wheel hub (23) with the oil seal bore
facing UPWARD.
3. Apply axle gear lubricant to the bearing rollers and
intsall the inner wheel bearing cone (25).
CAUTION : Do not damage the hub oil seal bore
surface in the wheel hub. Damage to this surface will
result in oil leakage after assembly.
NOTE : Eliminate oil leakage from the outer diameter
of the seal by applying a light film of non-hardening
sealant to the hub bore surface. The hub oil seal is a
“unitized” oil seal. The rotating seal lips are internal.
The rubber ribs in the bore of the seal seat onto the
spindle journal surface for static sealing. The ribs
must not be cut or damaged to avoid an oil leak path.
