🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and secure the vehicle

• Use the floor jack to lift the front of the Equinox.
• Place jack stands under the proper front support points and lower the vehicle onto them.
• Remove the front wheel with the 21mm socket.

Step 2: Disconnect the lower control arm from the knuckle

• Spray the lower ball joint nut and control arm bolts with penetrating oil.
• Use the 21mm socket and 21mm wrench to remove the lower ball joint nut.
• Use a ball joint separator (specialty) to free the ball joint from the steering knuckle.
• Support the knuckle so the brake hose is not strained.

Step 3: Remove the rear control arm bolt

• Use the 18mm socket and 18mm wrench to remove the rear control arm mounting bolt.
• If the bolt is a cam bolt, mark its position first with a paint marker.

Step 4: Remove the front control arm bolt

• Use the 18mm socket and breaker bar to remove the front mounting bolt.
• Lower the control arm out of the subframe.

Step 5: Install the new control arm

• Position the new control arm into place by hand.
• Install the front and rear mounting bolts finger-tight first.
• Insert the ball joint stud into the knuckle and install the nut.
• Use the 21mm socket to snug the ball joint nut.

Step 6: Torque the fasteners

• Lower the vehicle enough so the suspension is at normal ride height before final torque.
• Use the torque wrench to tighten the ball joint nut to 100 Nm (74 ft-lbs).
• Torque the control arm mounting bolts to 175 Nm (129 ft-lbs).
• If your cam bolts were removed, align your paint marks as closely as possible before tightening.

Step 7: Reinstall the wheel and lower the vehicle

• Install the wheel and hand-start the lug nuts.
• Use the 21mm socket to snug the lug nuts.
• Lower the vehicle and torque the lug nuts to 140 Nm (103 ft-lbs).

✅ After Repair
