Ball Joints


Ball Joints

Ball Joints are the connection between the wheels and suspension of a vehicle. They are found on the front suspension of most vehicles today. The ball and socket design help the joint pivot.

What are rotors and how do they work

What is it?

  • The amount of allowable pivot in any direction is limited by the size and shape of the ball joint throat opening and the original design limits placed on the suspension system.

How Does it Work?

  • The socket and bearing allow a smooth range of movement in all directions, which assists in the feel/ride of the vehicle and makes it easier to steer.

How is it Made?

  • A ball attached to a threaded stud is inserted into a metal housing.
  • A boot is installed over the housing to protect the internal components and grease, where applicable, from external contamination.

Why Does it Fail?

  • Ball joint becomes worn out.
  • Damaged boot may allow dirt into the bearing.
  • Dries out due to lack of lubrication.
  • You should have your alignment checked after having any front end work done on your car.

What are the Symptoms of Failure?

  • Increased tire wear.
  • Uneven tire wear.
  • Clunking noise on bumps or turns.
  • Front end shimmy.
  • Hard steering.

What are the Implications of Failure?

  • Angle of the tire can cause an abrupt halt or tire damage.
  • Debris can cause damage to others.
