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.
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 according to paragraph 13
Torque Specifications.

RADIUS RODS

Radius rods are used to secure the axles in the
proper transversal and longitudinal positions.
Five radius rods are provided on the front I-beam
axle suspension (four longitudinal and one
transversal). Refer to Figure 1 and Figure 5 for
details. These rods transmit both braking and
driving forces from the axles to the vehicle body.

Inspection

1. Clean all parts thoroughly.
2. Inspect radius rods for distortion and cracks.
We recommend the "Magnaflux" process to
detect cracks in the radius rod. Any
damaged part should be replaced with a new
one.
NOTE
New bushings should be used when rods are
replaced.
3. The radius rod bushings should be checked
periodically
