🔧 Front Lower Control Arm Replacement

Assumption: this covers the front lower control arms, which are the common service item on your Equinox when people say “control arms.” The front suspension uses press-fit joints and alignment-sensitive hardware, so the arm should be replaced carefully and the vehicle should be aligned afterward.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• Support the vehicle securely on jack stands before working underneath.
• Do not work under a vehicle supported only by a floor jack.
• Front suspension bolts are alignment-critical; the vehicle needs a professional alignment after the repair.
• Torque-to-yield fasteners may be used on some suspension joints; replace any one-time-use bolts and nuts if removed.
• If the lower ball joint is separating from the knuckle, keep hands clear of pinch points.
• Battery disconnect is not required for this repair.

Step 4: Remove the rear control arm bolt

• Use an 18mm socket and breaker bar to remove the rear mounting bolt.
• Mark the bolt orientation with a paint marker if needed.

Step 5: Remove the front control arm bolt

• Use a 15mm socket or 18mm socket to remove the front mounting bolt, depending on the fastener fitted to the vehicle.
