🔧 Front Lower Ball Joints - Replacement

On your Equinox, the front lower ball joint is part of the front suspension and must be serviced carefully to avoid damaging the knuckle, axle, or steering components. If the ball joint is loose or the boot is torn, replacement restores safe steering feel and front-end stability.

Assumption: This procedure covers the front lower ball joints. On this platform, some repairs are done by replacing the control arm assembly if the joint is not serviced separately.

Difficulty Level: Advanced | Estimated Time: 3-5 hours

⚠️ Safety & Precautions

• Support the vehicle with jack stands; never work under a vehicle held up only by a jack.
• Use caution around the front axle and CV joint. Do not let the knuckle hang by the axle shaft.
• The ball joint is part of the steering/suspension system. A failed install can cause loss of control.
• If equipped with an electronic parking brake, set it normally before lifting. No battery disconnect is normally required for this job.
• Keep fingers clear when separating the ball joint from the steering knuckle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front wheel

• Use a 21mm socket to remove the lug nuts and take off the wheel.
• Set the wheel aside safely.

Step 2: Access the ball joint

• Use a 17mm socket and 15mm wrench to remove any splash shield or lower access fasteners if they block the ball joint area.
• Spray penetrating oil on the ball joint nut and pinch area if rusty.

Step 3: Separate the ball joint from the steering knuckle

• Use a 19mm socket or the correct socket for the ball joint stud nut to remove the nut.
• Use a ball joint separator to pop the taper loose from the knuckle.
• Do not hammer on the axle.

Step 4: Remove the ball joint from the control arm or knuckle

• If the joint is pressed in, use a ball joint press kit with the proper adapters to press the old joint out.
• If the joint is bolted or riveted on, use the correct 18mm socket or Torx T30 screwdriver for the fasteners, then remove the joint.
• Clean the mounting area before installing the new part.

Step 5: Install the new ball joint

• Use the ball joint press kit to press the new joint in straight, if applicable.
• If bolted in, install the new joint with the supplied hardware and tighten evenly.
• Torque to manufacturer specification for the joint fasteners and stud nut.

Step 6: Reconnect the steering knuckle

• Align the ball joint stud with the knuckle and install the nut by hand first.
• Use a torque wrench and the correct socket to tighten the stud nut.
• Install a new cotter pin if the design uses one.
• Torque to manufacturer specification for the lower ball joint nut.

Step 7: Reassemble the front suspension area

• Reinstall any brackets or splash shields using the 17mm socket or correct fastener tool.
• Make sure the brake hose and ABS wire are routed correctly and not twisted.

Step 8: Reinstall the wheel

• Put the wheel back on and hand-tighten the lug nuts.
• Lower the vehicle and use a torque wrench with a 21mm socket to tighten the lug nuts in a star pattern.
• Torque to manufacturer specification for the wheel lug nuts.
