REMOVAL & INSTALLATION
Remove and install ONLY one lower control arm at a time. If both arms are removed at the same time, the axle could roll or slip sideways, making installation of the arms very difficult.
- Raise and support the rear of the vehicle using jackstands under the rear axle.
- If equipped, remove the stabilizer bar.
- Remove the control arm attaching fasteners, then remove the control arm.
- Position the control arm to the vehicle, then install the fasteners, but dot not tighten fully at this time unless the vehicle's weight is being supported by the rear axle. If the weight is on the suspension, tighten the control arm-to-frame nut to 70 ft. lbs. (95 Nm) and the control arm-to-axle bolt to 79 ft. lbs. (107 Nm).
The control arm fasteners must be tightened with the vehicle suspension at curb height. If the vehicle is supported by jackstands under the rear axle, this should be sufficient to duplicate that circumstance. If there is sufficient clearance and you so desire, the fasteners may be fully tightened after lowering the vehicle.
- If equipped with a stabilizer bar, install and tighten the mounting fasteners to 35 ft. lbs. (47 Nm).
- Remove the jackstands and carefully lower the vehicle. If not done already, tighten the control arm fasteners to specification.
