🔧 Ball Joints - Replacement

Assumption: This procedure is for the front lower ball joints on your Jetta, which are serviced with the front lower control arm assembly on this platform.

On your Jetta, the ball joint is part of the front suspension and must be replaced carefully to restore steering feel and tire wear control. Because it is pressed/bolted into the lower control arm area, the job involves lifting the front of the vehicle, removing the wheel, and separating the knuckle from the control arm area.

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

• Keep hands clear when separating the steering knuckle from the lower control arm.
• Do not let the brake hose or ABS wire hang by itself.
• Use a torque wrench on all suspension fasteners.
• Have the parking brake set and the transmission in gear.
• No battery disconnect is required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and secure the front of the car

• Use a floor jack to lift the front of the car at the proper jacking point.
• Place jack stands under the front support points and lower the car onto them.
• Remove the front wheel with a 19mm socket.

Step 2: Access the ball joint area

• Turn the steering wheel to give yourself more room on the side you are working on.
• Locate the lower ball joint where the control arm meets the steering knuckle.
• If equipped, remove any small splash shields or covers with a Torx T30 screwdriver.

Step 3: Disconnect the ball joint from the knuckle

• Use the correct triple-square XZN bit or 16mm socket to remove the ball joint fasteners, depending on the hardware on your car.

• Do not hammer on the knuckle.

Step 4: Remove the ball joint

• Use an 18mm socket and ratchet to remove the ball joint mounting bolts from the control arm area.

• Remove the ball joint from the vehicle.

Step 5: Install the new ball joint

• Position the new ball joint in place by hand first.
• Install new mounting bolts finger-tight.
• Use the torque wrench and tighten the ball joint mounting bolts to 70 Nm (52 ft-lbs).

Step 6: Reconnect the knuckle

• Seat the ball joint stud into the steering knuckle.
• Install the knuckle fasteners with the correct triple-square XZN bit or 16mm socket.
• Tighten the fasteners to 40 Nm (30 ft-lbs) plus 90°.

Step 7: Reassemble the wheel area

• Reinstall any splash shields with the Torx T30 screwdriver.
• Put the wheel back on.
• Snug the lug bolts with the 19mm socket.

Step 8: Lower and torque the wheel
