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

4. RADIUS ROD
Radius rods are used to secure the axles in the
proper transversal and longitudinal positions. Four
radius rods are provided on the front axle suspen-
sion (three longitudinal and one transversal), four
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 1 and 2 for details. These rods transmit
both braking and driving forces from the axles to
the vehicle body.

4.1 Inspection
The following instructions apply to all radius rods
used on this vehicle:
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 for signs of shearing, deterioration,
or damage. Any defective part should be re-
placed with a new one.
