ASSEMBLY
NOTE DO NOT use a petroleum or soap base lubricant. Such lubricants can cause adverse reactions
with the bushing, such as deterioration of the rubber, causing premature failure.
1. Lubricate the inner diameter of the torque rod end hub and the new rubber bushing with
light Naphthenic Base Oil, such as 60 SUS at 100°F, see Figure 8-5.
2. Support the torque rod end hub on the receiving tool with the end hub of the torque rod
centered on the receiving tool.
NOTE The straddle mount bar pin bushings must have the mounting flats positioned perpendicular
to axis of the torque rod.
3. Press directly on the straddle mount bar pin. The rubber bushings of the bar pin must be
centered within the torque rod end hubs.
4. When pressing in the new bushings overshoot the desired final position by approximately
3
/
16
", see Figure 8-6.
5. Press the straddle mount bar pin again from opposite side to center the bar pin within the
torque rod end hub, see Figure 8-7.

6. Wipe off excess lubricant. Allow the lubricant four hours to dissipate before operating vehicle.
IF THE TORQUE ROD ASSEMBLY IS NOT ALLOWED THE ALLOTTED TIME FOR THE LUBRICANT TO
DISSIPATE, THE BUSHING WILL SLIDE FROM THE TORQUE ROD END HUB. IF THIS OCCURS, THE
BUSHING MAY BE DAMAGED AND HE BUSHING WILL THEN NEED TO BE REMOVED AND A NEW
BUSHING RE-INSTALLED.
7. Install torque rod assembly as detailed in this section.
