Worn ball joints can cause excessive front tire wear, popping or creaking in the front end, extra play in the steering system, and pose a serious safety concern. Replace loose or worn ball joints with our quality replacement.

One way to diagnose a loose, or warn ball joint, is to jack the car up, so the wheel is off of the ground, then have someone try to move the wheel in and out. While they are moving the wheel check the ball joint for play, if it is moving you probably need to replace it.

  1. Step 1: Loosening the Lug Nuts and Hub Nut
    • Before lifting the car, loosen the lug nuts up with a 19 mm wrench, and the hub nut using a 35 mm socket. It's best to do this while the car is on the ground so the wheels won't move.
  2. Step 2: Raising and Securing the Car
    • Position the jack under the control arm with a jack stand under the frame.
    • Raise the car (most of the weight should be on the jack stand).
  3. Step 3: Removing the Brake Caliper
    • Remove the tire, and the hub nut and washer.
    • To remove the break caliper, there are two 18 mm bolts to remove—one on top and one on the lower backside.
    • Once those are off, pry the caliper right off with the wrench.
    • Remove the brake rotor.
  4. Step 4: Redistributing the Weight
    • Now, to redistribute the weight, move the jack out to the end of the control arm, and jack it up so that most of the weight in now on the jack with only a little weight on the jack stand.
  5. Step 5: Removing the Harness
    • First, disconnect the harness. Remove the clips on the left side of the harness, and use a screwdriver to pry it up off the frame.
    • It would be best to coat the nuts with penetrating oil at this time.
    • Take the small bolt off with the 10 mm wrench (put the bolt and the nut back into the control arm just for safe keeping so you'll know where they are).
    • Remove the last bolt on the frame—a 13 mm bolt.
    • Once the bolts are removed, pull the harness out and free. (Save the clips from the harness in case you need them to install)
  6. Step 6: Removing the Hub
    • There's three 18 mm bolts that hold the hub-one in the back, one in the middle of the top, and one in the front.
    • The front and rear ones can be reached with an impact wrench or regular wrench. The middle one, you'll need to use a hand wrench. (Swivel the steering to help you get at the bolt easier.)
    • Remove all three bolts.
    • Using the pry bar or screwdriver, pry against the steering knuckle. (Be careful not to bend up that backing plate too much.)
    • Pull out and away from the backing plate, and the hub is out.
    • (There is a little O ring that needs to be replaced correctly. If you are replacing the hub, transfer it to the new hub. If not, make sure it's in the correct spot.)
  7. Step 7: Removing the Jounce Bumper
    • There are two bolts where the ball joint is secured to the control arm. (If your ball joint hasn't been replaced before, you'll just see little round rivets.)
    • If it is rivets, use a cold chisel and pound them to shear them right off.
    • Remove these bolts or rivets on the front, in the back and underneath.
  8. Step 8: Removing the Ball Joint
    • Remove the cotter pin and the bolt-22 mm or 24 mm-from the ball joint.
    • Remove the cotter pin and the bolt-18 mm or 19 mm-from the tire rod end.
    • For the tire rod end, hit it with a couple of good hammer hits. Holding the control arm, give the ball joint a few whacks as well.
    • Take out all the bolts from the top of the ball joint.
    • Pull down on the control arm and towards the rear of the vehicle, and the ball joint will come out.
