Pivot bushing installation- First part of this post, gave details on removing the pivot bushing. This post is going to go through the steps to install the replacement pivot bushing.

  • Remember that the pivot bushing replacement tool is used both for removing the old pivot bushing (removing tool) and to installing the new one (installation tool).


The pivot bushing installation tool consists of a threaded rod (1), two thrust washers (2), a thrust bearing (3), two more thrust washers (2), a cover plate (4), a receiver tube (5), an additional drive disc (8), and a drive nut (9).

IMPORTANT! The centering ring of the receiver tube is used to center the receiver tube on the trailing arm receptacle. When the installation tool is used, the centering ring must always be positioned against the trailing arm receptacle.

Prior to installing the pivot bushing in the trailing arm receptacle, assemble the installation tool by placing the following components on to the threaded rod (1) in the following order (figure 8).

  • Two thrust washers (2)
  • Thrust bearing (3)

WARNING! Failure to use proper lubricant during pivot bushing installation could reduce vehicle stability which could result in death or serious injury.

  • DO NOT lubricate with oil or grease.

4. Insert the pivot bushing (7) into the receiver tube end (5) opposite of the centering ring. Make sure that the pivot bushing is properly aligned in the receiver tube using the bushing position locator as a reference point (figure 11). The bushing position locator of the replacement bushing must be aligned with the line on the outside of the receiver tube. The orientation index marked “Top” must face upward as illustrated in figure 10. I needed readjust the pivot bushing.
