IRS Bronze Bushings

Figure 1
The smaller diameter bronze bushings in your kit have been designed to replace the original roller bearings, tubes and seals. As with the hub carrier bushings, make sure that there are no burrs on the inner edges of the wishbone ends. If the wishbones have been painted or powder coated, remove any trace of paint which may have adhered to the inner bearing surfaces.

The bronze thrust washers supplied with your kit are designed to fit either side of the inner fulcrum bushings within the two original outer thrust washers which are retained. In fact you will see in Figure 2 that the bronze washers will slide over the protruding ends of the inner fulcrum bushings.

The combination of the new bronze thrust washers and the original outer thrust washers ensures that the wishbone remains centralized during suspension cycles.

Figures 2 and 3 below show the installation of both the new System Bronze thrust washers and the original outer thrust washers that are retained.
