Installation Guidelines
Suspension replacement requires proper safety gear and tools:
- Preparation: Secure the vehicle on jack stands, block the rear wheels, and remove the front tires.
- Disassembly: Unbolt the lower shock mount, sway bar link, and remove the ball joint cotter pin and castle nut. Use a pickle fork or ball joint separator to disconnect the knuckle.
- Swap: Remove the main frame pivot bolts and pull the old control arm assembly out.
- Installation: Bolt the new SCITOO Control Arm into place. Torque all fasteners to factory service manual specifications with the vehicle's weight resting on the suspension (normal ride height).
- Crucial Step: A professional wheel alignment is mandatory immediately following control arm replacement to ensure proper tire wear and handling.
