Steps
Raise the vehicle and remove the wheel
Loosen the wheel nuts while the car is on the ground, then raise and support the front securely on a stand. Remove the wheel and keep it clear of the work area.
Support the knuckle and release the arm
Support the steering knuckle with a strap or bungee so it cannot fall or strain the brake hose. Loosen the strut connection and ball joint fasteners, then separate the arm from the knuckle using an appropriate method.
Remove the sway bar brackets
Remove the sway bar bushing bracket fasteners and lift the brackets and bushings away. Note their orientation and inspect the rubber for wear before transfer or replacement.
Remove the old control arm
Use the correct hex bit to hold the upper arm bolt while loosening its nut. Move the knuckle aside under support, remove the arm's mounting bolt, and withdraw the control arm.
Install the replacement arm
Position the replacement arm in the subframe and start the mounting bolt by hand. Reconnect the ball joint and strut, then tighten fasteners to the vehicle specification while keeping the knuckle supported.
Tighten at ride height and refit bushings
Raise the suspension to approximate normal ride height before final tightening of bonded rubber bushings. Reinstall the sway bar bushings and brackets, then torque all suspension fasteners to the manufacturer's values.
Reinstall the wheel and check alignment
Reinstall the wheel and torque its nuts in a star pattern to specification. Inspect the brake hose and ABS wire for proper routing, and have the alignment checked before normal driving.
Check your vehicle’s repair manual for exact specifications and fit.
