How to Use Ball Joint Service Tools

Ball joints are crucial components in your vehicle's suspension system. When they become damaged or worn out, it affects steering precision and wheel alignment. Replacing worn ball joints yourself with the proper tools saves money compared to paying a mechanic. This detailed guide covers everything you need to know for DIY ball joint replacement.

What Do Ball Joints Do?

The role of the ball joint

Ball joints are spherical bearings that connect the control arms to the steering knuckles on your vehicle's suspension and steering linkage. They allow the front wheels and tires to pivot and turn smoothly.

Ball joints have a rounded end that fits into a socket. A flexible rubber boot encloses the joint to keep out dirt and retain grease. The constant motion of driving causes the ball joint casing to eventually wear out. Lack of lubrication also contributes to premature failure.

Symptoms of Worn Out Ball Joints

How can you tell when your ball joints need replacement? Look for these common signs:

  • Uneven tire wear - Edge of tread wears faster indicating alignment issues
  • Wandering, loose steering - Vehicle pulls to one side, hard to keep straight
  • Popping or knocking when turning - Damaged joint moves unevenly
  • Boot torn - Dirt and water enter to contaminate grease
  • Excess play when rocking top and bottom of tire - Up/down motion indicates looseness

    If you notice any of these symptoms, inspect the ball joints closely. Have a helper rock the wheels while you watch for excessive play. Catching bad ball joints early prevents further steering and suspension damage.

    Ball Joint Anatomy and Function

    Ball joints allow free motion in two planes simultaneously:

    • Pivoting - Wheels turn left or right for steering
    • Articulation - Suspension travels up and down over bumps

    The ball stud end connects to the steering knuckle with a tapered hole. A threaded nut secures it in place. The spherical bearing end fits into the control arm socket. It rotates freely within the plastic casing.

    A rubber boot covers the ball joint housing. It keeps lubricating grease in and dirt/debris out. Ball stud wear is minimized by the constant grease coating.

    Why DIY Ball Joint Replacement?

    Replacing worn ball joints restores precise steering control and wheel alignment. The job typically costs $150-$350 for parts and labor at a shop. With DIY ball joint tools, you can do it yourself and save money.

    Ball joint replacement is not an overly complicated task. But it does require proper tools and techniques for best results. With some time and patience, you can swap ball joints safely in your home garage.
