Steps
Raise the vehicle and remove the wheel
Loosen the lug nuts slightly, raise and support the vehicle on stands, then remove the wheel to access the upper arm.
Disconnect the ball joint and arm
Remove the ball joint nut and support the spindle with a bungee cord. Tap the knuckle carefully to release the taper, then move nearby reservoirs aside as needed and remove the two strut tower bolts.
Install the replacement arm
Guide the new arm into the wheel well and insert its captured mounting bolts. Seat the ball joint stud in the spindle and start its nut by hand.
Secure the arm and nearby components
Tighten the ball joint nut and arm mounting nuts to the vehicle's specifications. Reposition and secure any reservoirs or access covers moved during removal.
Reinstall the wheel
Fit the wheel and hand-start its lug nuts. Lower the vehicle so the suspension carries its normal load, then torque the lug nuts in a crossing pattern to specification.
Check your vehicle’s repair manual for exact specifications and fit.
