4. Four bushings (Fig. 5–2) help locate the axle
supports on the vehicle frame. Insert the bushings
into the holes on the front and rear axle supports.
Align the bushings and supports with the frame.
Raise the axle as required to align the supports with
the frame.
5. Install the 3/4-10 x 5-1/2" Grade 8 hex-head
capscrews (item 11), new 3/4-10 hex-lock elastic nuts
(13), and 3/4" hardened flat washers (12) securing
the front and rear axle supports to the vehicle frame.
Torque to 250 lb/ft (340 Nm).
6. If required, attach the cylinder anchor (8) and anchor
plate (9) to the axle with 7/8-9 x 12" hex-head
capscrews (6), 7/8" hardened flat washers (7), and
new 7/8-9 hex-lock nuts (10). Torque to 380 lb/ft (515
Nm).
Note: Always use new lock nuts to help ensure proper
fastening.
7. Move the cylinder (15) into position on the axle
cylinder anchor (8). Insert a 1.5" diameter cylinder-
mount pin (3) through the cylinder (15) and cylinder
anchor (8). Secure the cylinder-mount pin (3) with a
5/16-18 x 3-1/2" hex-head capscrew (5) and a new
5/16-18 hex-lock nut (4). Torque to 18 lb/ft (24 Nm).
Note: Always use new lock nuts to help ensure proper
fastening.
8. Apply multi-purpose grease through the self-tapping
lube fitting (1) to lubricate the self-align bearing (2)
and the cylinder-mount pin (3).
9. If reinstalling an axle previously removed from the
vehicle, position the driveshaft flange yoke on the
axle according to the alignment marks made earlier.
If installing a new axle, note the position of the
driveshaft yoke at the transfer case. Align the
driveshaft yoke on the axle in the same plane as the
yoke on the transfer case (Fig. 5–3).
Note: The drive shaft assembly is a balanced assembly.
The yokes at each end of the drive shaft must be in the
same plane to help prevent excessive vibration (Fig. 5–3).
Figure 5–3. Align yokes in the same plane as shown.
10. Install the wheel and tire assemblies.
Note: The wheel and tire assemblies must be installed
with the directional tread pattern “arrows” facing in the
direction of forward travel (Fig. 5–4 and Fig. 5–6).
Figure 5–4. The tread “arrows” must point
in the direction of forward travel (also see Fig. 5–6).
