Steps
Raise the vehicle and remove the wheel
Loosen the rear lug nuts, raise and support the vehicle securely, then remove the wheel to reach the upper control arm and sway-bar link.
Disconnect the sway-bar link
Counterhold the link stud while removing its nut. Lift the link clear of the control arm without damaging its bushings or boot.
Separate the ball joint
Remove the cotter pin and support the suspension with a floor jack to unload the joint. Remove the castle nut, separate the ball joint from the knuckle, and lower the jack carefully.
Remove the old upper arm
Remove the rear control-arm pivot fasteners and slide the arm out. Compare the replacement arm orientation and inspect the mounting points for damage.
Install the new control arm
Position the replacement arm and start its pivot bolts by hand. Raise the suspension as needed to reconnect the ball joint, then tighten fasteners to vehicle specifications.
Reconnect the sway bar and wheel
Reinstall the sway-bar link and tighten it to specification. Fit the wheel, lower the car, and torque the lug nuts to vehicle specification in a star pattern.
Check alignment and operation
Inspect the cotter pin and all suspension fasteners. Have the rear alignment checked and make a cautious road test, listening for clunks or tire scrub.
Check your vehicle’s repair manual for exact specifications and fit.
