⚠️ Safety & Precautions

• Use jack stands on solid ground. Never work under a vehicle supported only by a jack.
• Chock the rear wheels before lifting the front.
• Loosen axle and suspension fasteners only with the vehicle safely supported.
• Do not let the steering knuckle hang by the brake hose or ABS wire.
• After repair, get a front-end alignment. This job changes suspension geometry.
• Battery disconnect is not required.

Follow these steps in order:

Step 1: Raise and support the front end

• Use a floor jack to lift the front of the vehicle at the proper lift point.
• Set the vehicle securely on jack stands.
• Remove the front wheel with a 21mm socket.
• Shake the vehicle lightly before working.

Step 2: Free the ball joint from the steering knuckle

• Use a 17mm socket and breaker bar to remove the ball joint nut.
• Remove the cotter pin first if equipped, using pliers if needed.
• Use a ball joint separator to break the taper loose from the knuckle.
• If needed, tap the knuckle lightly with a hammer while applying pressure with the separator.

Step 3: Remove the ball joint from the lower control arm

• Use a 14mm socket or 17mm socket to remove the ball joint mounting bolts, depending on fastener style.
• Support the steering knuckle with a bungee cord or mechanic's wire.
• Remove the old ball joint from the control arm.
• Do not pull on the brake hose.

Step 4: Install the new ball joint

• Position the new ball joint in the lower control arm.
• Start the mounting bolts by hand.
• Use a torque wrench and 14mm socket or 17mm socket to tighten the mounting bolts.
• Torque to 59 Nm (44 ft-lbs) for the ball joint mounting bolts.

Step 5: Reconnect the ball joint to the knuckle

• Align the ball joint stud with the steering knuckle.
• Install the new nut using a 17mm socket.
• Torque to 49 Nm (36 ft-lbs), then continue until the cotter pin hole lines up if applicable.
• Install a new cotter pin.

Step 6: Reassemble the wheel and repeat on the other side

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle with the floor jack.
• Use a 21mm socket and torque wrench to tighten the lug nuts.
• Torque to 103 Nm (76 ft-lbs).
• Repeat the same procedure on the other side if both ball joints are being replaced.
