6. Visually inspect the shock mountings and
vehicle mounting for:
a) Broken mounts;
b) Extreme bushing wear;
c) Shifted bushing or sleeve;
d) Deep cracks in bushing material (shallow
surface cracks are normal);
e) Loose shock absorber pins;
f) Presence of convex washers, and their
position relative to the rubber bushing.
4.2.2 Removal
1. Remove nuts and washers from shock
absorbers on upper and lower mounting
pins, taking care to identify the inner and
outer washers to ease reinstallation. Refer
to figure 40 for details.
2. Remove the shock absorber assembly from
pins.
3. Remove the two inner bushings from the
shock absorber and discard them.

4.2.3 Installation
1. Ensure that the shock absorber mounting
pins are tight and that the threads are not
stripped.
2. Install new rubber mounting bushings on
shock absorbers (upper and lower).
3. Place the inner washers (with washer
convex side facing the shock absorber
rubber bushing) on each shock absorber pin
(Fig. 41).
4. Install the shock absorber eyes over the
mounting pins, then the outer washers (with
washer convex side facing the shock
absorber rubber bushing) on each shock
extremity.
NOTE
If shock absorber pins are removed, they must
be reinstalled using “loctite” (see “Parts
Specifications” in this section).

5. Place the lower and upper mounting pin
stud nuts and torque to 70 - 80 lbf-ft (95 –
110 Nm).
4.3 RADIUS RODS
Radius rods are used to secure the axles in the
proper transversal and longitudinal positions.
Four radius rods are provided on the drive axle
suspension (three longitudinal and one
transversal) and also four on the tag axle with a
layout similar to the drive axle. Refer to figures
36, 37 and 38 for details. These rods transmit
both braking and driving forces from the axles to
the vehicle body.
