Suspension Ball Joint Replacement

What is a ball joint?

Ball joints link the steering knuckle (which supports the wheel hub, bearing, and wheel) to the lower and upper control arms. They allow the suspension to move freely up and down and aid in the steering of the vehicle.

How does a ball joint work?

The ball joint is made up of a ball and socket that is encased in a lubricant-filled rubber boot. The ball joint is connected to the steering knuckle that houses the wheel hub and bearing (this is what the wheel is bolted to), and the control arm, allowing the suspension to travel up and down over bumps, and to turn left and right for steering. The ball joint is also the smallest part that connects the wheel and tire to the vehicle.

What are the symptoms related to a bad ball joint?

A "clunk" or "knock" when turning, or when going over bumps, can indicate a problem with a ball joint. The sensation is often felt in the floorboard of a vehicle when driving. A repair technician may notice if a ball joint is leaking lubricant from a worn or torn boot during an inspection or a related repair. Excessive wear on the inside or outside edges of the front tires can sometimes indicate problems with the ball joints as well.

Can I drive with a ball joint problem?

A vehicle with a ball joint that is beginning to wear out can be driven, but as the wear increases, so do the chances of premature tire wear and poor vehicle handling. If you suspect that a ball joint is beginning to wear, have a technician evaluate the problem as soon as possible. A vehicle with a significantly worn ball joint should not be driven. The ball joint is a small part of the suspension and consists of a simple ball and socket. If the ball joint fails completely, it is possible for the control arm to detach from the steering knuckle and cause serious damage or injury.

Suspension Ball Joint Replacement Cost Estimates

How is a ball joint replaced?

To replace a ball joint, a technician will raise the vehicle in the air on a hoist (or jack and jack stands) and remove the front wheel in order to access the ball joint. The ball joint is disconnected from the lower or upper control arm and the steering knuckle (by removing the fasteners and using a ball joint separator, or "pickle fork"), the suspension is separated to allow the ball joint to come free, and the new part is installed. Some vehicles require that the steering knuckle be disconnected from the strut in order to get to the retaining nut on one side of the ball joint. Tension between components in the suspension may make separation difficult.

RepairPal recommendations for ball joint issues

RepairPal recommends getting a four-wheel alignment after the ball joint has been replaced. If the tires show signs of significant wear, new tires would also be recommended.

What to look out for when dealing with ball joint issues

The front suspension components often have a good deal of tension between them. This could make separating the steering knuckle and the control arm from the ball joint difficult and care should be exercised during ball joint replacement. A ball joint with tapered studs is sometimes difficult to remove from its mounts in the steering knuckle or control arm. Also, the vehicle needs to be safely raised and supported in order to complete this repair.

Can I replace a ball joint myself?

On most vehicles, replacement of a ball joint is an intermediate DIY repair. Care needs to be exercised when lifting and supporting the vehicle to prevent serious injury. This repair usually requires a ball joint separator (or "pickle fork") used to separate the tapered shaft of the ball joint from its mount in the control arm and/or the steering knuckle. The tension between components in the suspension often makes it difficult to separate the knuckle or control arm from the ball joint. If you are not comfortable with lifting a vehicle, or with working on parts under tension, refer the repair to a professional technician.
