• If the vehicle has a torque-to-yield fastener in this area, replace it with a new one.
• Front suspension work can change alignment. A professional wheel alignment is required after repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the wheels

• Use a 19mm socket to loosen the lug nuts before lifting.
• Raise the front with a floor jack and support it with jack stands.
• Remove both front wheels with the 19mm socket.

Step 2: Access the ball joint area

• Turn the steering wheel by hand to give yourself more room on the side you are working on.
• Use a paint marker to mark the position of any alignment-related bolts you remove.

Step 3: Separate the ball joint from the knuckle

• Remove the cotter pin with needle-nose pliers if your joint uses one.
• Use a 17mm socket or 14mm socket to remove the ball joint pinch bolt, depending on the fastener size on your vehicle.
• Use a ball joint separator to break the taper loose from the steering knuckle.
• If needed, tap the knuckle lightly with a hammer while keeping the separator under tension.

Step 4: Remove the ball joint from the control arm

• Use the correct 14mm socket or 17mm socket to remove the ball joint mounting fasteners.
• Pull the ball joint free from the lower control arm.
• Inspect the control arm bore for rust, wear, or damage before installing the new part.

Step 5: Install the new ball joint

• Position the new ball joint in the control arm in the same orientation as the old one.
• Start all bolts by hand first with the correct socket.
• Install the pinch bolt and nut.
• Torque the ball joint fasteners to factory specification.
• Install a new cotter pin if equipped.

Step 6: Reconnect the knuckle

• Raise or lower the control arm slightly with the floor jack so the ball joint stud lines up with the knuckle.
• Insert the stud fully into the knuckle.
• Install and torque the pinch bolt and nut to factory specification.

Step 7: Reassemble and repeat on the other side

• Reinstall the wheel with the 19mm socket.
• Lower the vehicle and torque the lug nuts to factory specification.
• Repeat the same steps on the opposite side.
• Replace ball joints in pairs.

Step 8: Final torque and inspection

• Torque all suspension fasteners with the torque wrench to factory specification.
• Check that brake hoses, ABS wires, and the axle boots are not twisted or pinched.
• Verify both front wheels spin and steer freely.

✅ After Repair
