🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and secure the vehicle

• Use a floor jack to raise the front of the vehicle at the proper lift point.
• Set the vehicle onto jack stands.
• Remove the front wheels using a 19mm socket.
• Do one side at a time if you want a reference.

Step 2: Disconnect the ball joint from the knuckle

• Use a 17mm socket or 19mm socket to remove the lower ball joint nut.
• Use a ball joint separator (specialty) to break the ball joint loose from the steering knuckle.
• If needed, tap the side of the knuckle with a hammer to release the taper.
• Do not pry on the boot.

Step 3: Remove the control arm mounting bolts

• Use a 17mm socket, 19mm socket, or 21mm socket depending on the fastener size used on your vehicle.
• Remove the front and rear control arm pivot bolts.
• Support the arm with one hand as the last bolt comes out.
• Remove the control arm from the vehicle.

Step 4: Install the new control arm

• Position the new control arm into place.
• Start all pivot bolts by hand first with the correct socket.
• Insert the ball joint stud into the steering knuckle.
• Install the new ball joint nut by hand.

Step 5: Snug the fasteners

• Use a ratchet to snug the pivot bolts.
• Use a ratchet to snug the ball joint nut.
• Do not final-torque the pivot bolts yet.

Step 6: Torque at ride height

• Reinstall the wheel and lower the vehicle so the suspension is at normal ride height.
• Use a torque wrench to tighten the control arm pivot bolts.
• Torque the control arm pivot bolts to 108 Nm (80 ft-lbs).
• Torque the lower ball joint nut to 44 Nm (32 ft-lbs).
• Ride-height torque helps the bushings last longer.

Step 7: Reinstall the wheels

• Install the wheels and hand-tighten the lug nuts with a 19mm socket.
• Lower the vehicle fully.
• Use a torque wrench to tighten the lug nuts to 108 Nm (80 ft-lbs) in a star pattern.
