INSTALLATION

! 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.

Installing the Pivot Bushing

1. Lubricate the threads on the threaded rod (4).

2. Apply installation lubricant evenly to the internal 
surface of the receptacle as illustrated in Fig. 8 and to 
the external surface of the replacement pivot bushing as 
shown in Fig. 9.

3. Use installation lubricant P-80 Emulsion.

 WARNING

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

4. Insert the pivot bushing into the receiver tube end 
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 (Fig. 10). 
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 Fig. 10. If need be, readjust 
the pivot bushing.

5. Push the pivot bushing and the drive disc (6) 
completely into the receiver tube as shown in Fig. 11.

6. Insert the threaded rod (4) of the pre-assembled 
installation tool from the wheel side through the 
receptacle, making sure that the cover plate (4) is 
positioned properly against the receptacle as illustrated 
in Fig. 12.

7. Slide the receiver tube (5) over the exposed threaded 
rod (4) with the centering ring of the receiver tube 
facing toward the receptacle until the receiver tube rests 
squarely on the receptacle. Fasten the drive nut ensuring 
the drive plate is in place. 

Make sure that the line previously drawn on the external 
surface of the receptacle is aligned with the line on the 
receiver tube.

Note: Use the same tool for installation.
