Use caution and common sense while working on the vehicle. If you lack the necessary equipment or expertise to perform this operation, have the Control Arms installed by a mechanic with the proper tools and experience. Failure to follow safe practices may result in injury.
If you are installing lower control arms with the uppers, it is recommended to install the lowers first.
|
| Step
1. Raise Vehicle |
| |
|
| 1A. With the front wheels properly blocked;
raise the rear end of the vehicle as high as safely possible.
Place jack stands on a solid area under the frame of the car,
not the rear end. Remove the wheels at this time. |
| 1B. Tip: Place the jack stands slightly forward of the
control arm mounting bolt or on the mounting plate of
the subframe connectors if you have them. |
| |
|
| Step
2. Raise Rear Axle |
| |
|
| Using a floor jack under the center section
of the rear end, raise the rear axle of the vehicle until it
is supported by the jack and the shocks are no longer topped out (about 2 inches). |
| |
|
| Step
3. Support Rear Axle |
| |
|
| Place jack stands securely under the axle for support. The rear axle should not be supporting the full weight of the vehicle. |
| |
|
| Step
4. Remove Mounting Bolts |
| |
|
| Remove the 2 control arm mounting nuts and bolts securing the stock control arm.
|
| |
|
| Step
5. Remove Control Arm |
| |
|
| Remove the control arm from the vehicle.
|
| |
|
| Step
6. Clean & Inspect Mounting Points |
| |
|
Fully inspect all mounting
points and remove any debris. Apply a light coating of the
supplied synthetic grease to all surfaces that will be in contact
with the bushings. At this time, also coat the outside of the
bushings themselves with the same supplied grease.
|
| |
|
| Step
7. Install Control Arm |
| |
|
Install the new control arm using the reverse procedure of removal.
|
| Tip: Because the new Polyurethane bushings are much firmer
than the stock rubber, it may be necessary to gently persuade
the control arm into the mount using a rubber mallet or other
suitable tool, taking care not to damage the finish. It may also be helpful to place the jack under the front of the differential, just behind the driveshaft flange if the axle has rotated during disassembly.
|
| |
|
| Step
8. Tighten Hardware
|
| |
|
| At this time; tighten both mounting bolts
to 70-80 lb-ft. |
| |
|
| Step
9. Install 2nd Control Arm |
| |
|
| Repeat this procedure for the other
side. |
| |
|
| Step
10. Adjust Pinion Angle |
| |
|
| Your new control arms are pre-set at the factory length. If you need to adjust your pinion angle from stock, please follow the instructions below. Before setting the pinion angle, both control arms should be installed.
|
| |
|
| Step
11. Inspect Installation |
| |
|
| Inspect the installation, insuring
that suspension is free to travel.
At this time, install the wheels and lower the vehicle. |
