Why replace ball joints?
Ball joints deteriorate if dirt, grit and impurities get inside or grease escapes, leading to a lack of lubrication. Added to this, rusting and general wear and tear also damage these suspension parts. The effects of this deterioration are excessive play and looseness (beyond the manufacturer’s specifications). While healthy ball joints allow for smooth movement from side to side, they shouldn’t wiggle or jolt up and down. This is a clear indicator that you need to look into ball joint replacement.

Watch out for these symptoms of worn ball joints:

• clunky, knocking noises, particularly when going over bumps
• creaky or squeaky noises when the suspension moves
• drifting to the side
• shaky or loose-feeling steering
• uneven or premature tyre wear or feathering

Here are the steps to replace the ball joints on your suspension:

• Park the car on stable ground in a garage or parking lot
• Use a car jack to lift the car, and chock the rear wheels so that the car will not roll away.
• Take off the wheel and place it securely away from the car
• Undo the brake callipers, brake rotors and all the hydraulics attached to it
• Take off sway bars that may be attached to the wheel hub
• Separate the upper control arm and lower control arm from the suspension using a ball joint fork. Detach the steering knuckle and coil spring
• You may require a mallet to force the steering knuckle away from the ball joint
• The ball joint needs to be removed from its housing. Take away any snap rings that are holding the ball joint in place
• The ball joint press should be used to remove the ball joint from the control arm
• Inspect the ball joint for any signs of damage or defects. A service manual will describe the state of a worn-out ball joint
• The new ball joint should be pressed into the control arm using the ball joint press
