Component Replacement Instructions
8. Trunnion Clamp Replacement
and Installation
IMPORTANT:
It is recommended that the trailer be unloaded
before beginning service procedures.
Failure to properly secure vehicle prior
to commencing work could create a roll
and/or crush hazard which, if not avoided,
could result in death or serious injury.
1. Support the vehicle frame with the adequate jack stands.
Set the jack stand height at approximately 2" (51mm)
above the suspension’s specified ride height.
Always refer to the trailer manufacturer’s
approved method of raising the trailer.
If jack stands are used, they MUST be of
sufficient strength and positioned according
to OEM recommendations. Failure to use
approved jack pad locations could cause
the trailer to fall, resulting in death, serious
injury and/or component damage to the
trailer. NEVER use the axle or suspension
components to raise the trailer.
Sufficiently support the suspension prior
to removing the 1-1/8" U-bolts. Failure to
properly support the suspension prior to
trunnion disassembly could result in death
or serious injury.
2. Remove the nuts, U-bolts, trunnion clamp, and spring
saddle from the trunnion connection
(Figure 11)
.
3. Remove trunnion bushing and wear washers. Inspect the
wear washers for excessive wear prior to re-assembling
the new trunnion bushing. If excessive wear exists (after
the trunnion clamp has been replaced), replace the wear
washers and new trunnion bushing.
4. Remove the trunnion clamp attaching bolts. Remove the
trunnion clamp tube from the trunnion tube. Inspect the
frame brackets for any cracks; clean for flush mounting
of the new trunnion clamp to the frame brackets.
5. Assemble the new trunnion clamp to the trunnion
tube making sure it is in the same location as the one
removed. If both clamps were replaced, pre-assemble
the trunnion clamps to the trunnion tube in the same
location as the old trunnion clamps (approximately
10-1/8" from the end of the trunnion tube). Install the
5/8" fasteners to help locate the trunnion tube assembly
on the frame bracket
