🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the wheel

• Use a 21mm socket to remove the front wheel lug nuts.
• Remove the wheel and set it aside flat.

Step 2: Access the ball joint area

• Use a 14mm socket and trim clip removal tool to remove any splash shield fasteners blocking access.
• Inspect the lower control arm, steering knuckle, and ball joint for damage.

Step 3: Separate the ball joint from the knuckle

• Use a 17mm socket and breaker bar to remove the ball joint pinch bolt and nut.
• Use a ball joint separator (specialty) to free the ball joint stud from the knuckle.
• Do not strike the stud threads.

Step 4: Remove the ball joint from the lower arm

• Use a 14mm socket or 19mm socket depending on the fastener style to remove the ball joint mounting hardware.
• Lower the arm slightly with a pry bar if needed to release tension.
• Remove the old ball joint.

Step 5: Install the new ball joint

• Position the new ball joint in the control arm.
• Install the mounting hardware finger-tight first.
• Insert the stud into the knuckle and install the new pinch bolt and nut.
• Torque to 49 Nm (36 ft-lbs) for the pinch bolt, if your replacement hardware matches the factory fastener style.

Step 6: Tighten the mounting fasteners

• Use the appropriate 14mm socket or 19mm socket to tighten the ball joint mounting fasteners.
• Torque to 49-68 Nm (36-50 ft-lbs) for the ball joint mounting fasteners, depending on the replacement hardware design.
• Install a new cotter pin if your setup uses one.

Step 7: Reinstall the wheel

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle to the ground.
• Use a torque wrench and 21mm socket to tighten the lug nuts in a star pattern.
• Torque to 108 Nm (80 ft-lbs).

Step 8: Final inspection

• Turn the steering wheel lock-to-lock and confirm there is no binding.
• Check that all fasteners are fully seated.
• Road test slowly and listen for clunks or popping.
