Installation Guide
A wheel alignment is highly recommended after installation:
- Preparation: Secure the vehicle on jack stands and remove the front driver-side wheel.
- Disassembly: Disconnect the sway bar link and the lower ball joint from the steering knuckle.
- Removal: Unbolt the two main frame mounting bolts and remove the old control arm.
- Installation: Position the new Control Arm Assembly and hand-tighten the frame bolts.
- Final Torquing: Attach the ball joint to the knuckle. Important: Only perform the final torque of the frame bolts once the vehicle is back on the ground at normal ride height to prevent bushing bind.
- Alignment: Visit a professional shop for a 4-wheel alignment to ensure even tire wear.
