🔨 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 flat so it cannot roll.

Step 2: Free up the steering knuckle

• Use a wrench set and socket set to remove the fasteners holding the brake hose bracket or ABS wire brackets as needed.
• Move the line aside gently so it will not stretch.
• Do not let the brake hose hang.

Step 3: Separate the lower ball joint from the knuckle

• Use a ball joint separator tool (specialty) to break the lower ball joint loose from the steering knuckle.
• If needed, use a hammer to help shock the taper free.
• Support the knuckle so it does not drop suddenly.

Step 4: Remove the lower ball joint from the control arm

• Use the ball joint press kit (specialty) to press the old ball joint out of the lower control arm.
• Clean the bore with a wire brush before installing the new part.
• Clean metal makes pressing much easier.

Step 5: Install the new lower ball joint

• Use the ball joint press kit (specialty) to press the new ball joint into the control arm squarely.
• Install the snap ring using needle nose pliers if your replacement uses one.
• Torque to 70 Nm (52 ft-lbs) for the ball joint retaining fasteners if equipped with bolts.

Step 6: Reconnect the steering knuckle

• Raise or lower the knuckle as needed and guide the ball joint stud into the knuckle.
• Install the nut using a wrench set and tighten it securely.
• Torque to 203 Nm (150 ft-lbs) for the lower ball joint nut.

Step 7: Reinstall brackets and wheel

• Reinstall any ABS wire or brake hose brackets using a socket set.
• Put the wheel back on and hand-tighten the lug nuts.
• Torque to 204 Nm (150 ft-lbs) for the lug nuts.

Step 8: Repeat on the other side

• Replace ball joints in pairs so both sides wear evenly.
• Repeat the same steps on the opposite side.

✅ After Repair

• Start the truck and turn the steering wheel lock-to-lock to check for binding.
