Installation instructions

TOOLS NEEDED:
Following are the minimum recommended tools that may be required to install the rear camber shims.

Car jack (and jack stands)
Lug nut wrench
Small, flathead screwdriver
Ratchet with socket sizes: 10mm, 12mm, 14mm, 17mm

INSTALLATION:
Read through the following instructions thoroughly at least once before starting. Estimated time for completion of installation: approximately 60 minutes.

Step 1: Removal of rear wheel
Activate the emergency/parking brake, and jack up the rear end of the vehicle. Secure the vehicle on jack stands before proceeding. Loosen the lug nuts and remove the rear wheel. Look behind the rear hub assembly (Figure 1).

Figure 1: All of the work will be performed behind the rear hub assembly, the side indicated by the arrow

Step 2: Removal of rear hub assembly
Stick a small, flathead screwdriver into the ABS plug and use it to push down on the tab as you pull the end of the plug to remove it (Figure 2). Then remove the 10mm nut affixing the parking brake cable bracket (Figure 3, A), and the 14mm bolt for the brake hard line (Figure 3, B). Now you are ready to unbolt and remove the four 12mm bolts that attach the rear hub assembly to the suspension arm (Figure 4). Once all four bolts are removed, slowly pull the hub assembly away from the suspension arm, making sure not to kink or bend the brake line. The hub assembly will only need to be pulled a few inches from the suspension arm to install the camber shim.

Figure 2: Insert a flathead screwdriver into the top end of the sensor plug and push down to lift the plug’s latch.

Figure 3: Arrow A points to the 10mm parking brake cable bracket nut, and Arrow B to the 14mm brake line bracket bolt.

Figure 4: These are the four 12mm bolts affixing the rear hub assembly.

Step 3: Installation of camber shim
Place a corresponding camber shim over the rear side of the hub assembly (Figure 5) according to the side of the car that you are working on (the R shim goes with the right, or passenger side hub, and the L shim goes with the left, or driver’s side hub). Be sure that the L or R mark on the camber shim is facing up, and towards the outside of the car as seen in Figure 5 (i.e. the side with the mark must make contact with the hub, not the suspension control arm bracket), and then place the hub assembly with shim installed back on the suspension arm bracket.

Figure 5: Here the “R” camber shim is shown about to be installed on the right side (passenger side) hub. The mark is facing up, and towards the hub, or outside of the car.

Step 4: Installation of backing plate shims
With the hub and camber shim settled back on the suspension control arm bracket, move to the back side of the bracket and place a backing plate shim with the arrow mark facing up, and towards the outside of the car in alignment with two of the mounting bolt holes (Figure 6). Check to make sure that you have the pieces oriented as shown in Figure 7. Run two of the 17mm bolts provided in the kit, with split lock washers installed, through the backing plate shim, and thread them into the hub assembly hand tight. Place another dog bone piece over the remaining set of mounting holes in the correct orientation, and run two 17mm bolts through them. (If the bolts do not go in easily, the hub assembly might have shifted slightly during removal. To realign the mounting holes, simply release the parking brake, grab and rotate the assembly by the drum brake, and reapply the parking brake when the holes are aligned.) Complete camber shim installation by tightening the four mounting bolts in a cross pattern in two steps, first hand tight, and then to a final torque of 46 ft-lb.

Figure 6: Take extra care to mount the backing plate shims (dog bones) with the arrows pointing up, and the side with the arrow mark facing towards the outside of the car (i.e. the arrow side should touch the suspension control arm). This image shows one dog bone already installed with the bolts just hand tight, and the second dog bone being installed in the correct orientation. Note that these dog bones must be installed behind the control arm bracket, opposite of the side where the camber shim and hub rest.

Step 5: Reinstallation of components
With the rear hub assembly reinstalled with the camber shim, it is time to reinstall the other fasteners that were previously removed. Maneuver the brake line into its bracket and tighten its mounting bolt. Then attach the parking brake bracket nut and torque to 48 in-lb. Finally, plug the ABS sensor cable back into its plug. Mount the wheel, lower the car, and torque the wheel lug nuts to specification. Installation on the other side is exactly the same.
