How to repair or replace ball joint?

Sometimes it is possible to perform component repair, for example, replace the fastening or sealing elements. But this can be performed only at a service station and only if the component didn’t suffer corrosion. However, manufacturers recommend to replace the whole component if it is broken down, because driving with a faulty ball joint is very dangerous for the car and passengers. If you have certain skills and a special remover tool, you can do it yourself. You’ll need to perform the following actions:

  1. Render vehicle stationary, unscrew the bolts retaining the wheel, and lift the car body with the help of a jack.
  2. Unscrew the nut of the ball pin.
  3. Detach the component from the arm with the help of a remover tool and unscrew fastening bolts.
  4. Demount the defective part.
  5. Install a new component on the car, treating it with special anti-corrosion compound first.

Ball Joint Information

Ball joint is located at the bottom of the car. Steering and suspension ball joints in comparison with other components of friction work in quite difficult conditions. They are sanded and dusted, watered with dirty water or even covered with water. The only thing is that they are not subject to heating. You can check and replace the ball joint without any assistance. To examine this part, lift the car and place it on supports. Carefully inspect the covers for cracks, cuts or signs of leakage and then replace them if necessary. Then try to press the ball joint up or down. If you can do this, the ball joint is worn out. Ask your assistant to shake the wheel and tap the ball joint nut. If it moves, ball joint tail is worn out. In this case it is necessary to replace the joint.

To replace the ball joint, lift the car and remove the wheel. Then unscrew the bolt fastened to the ball joint control arm, but do not remove it immediately.

Unscrew the nut on the tail of the ball joint with a few turns. Disconnect the ball joint from the stub axle and remove the nut. Remove the two bolts that hold the ball joint to the control arm and then remove the ball joint. To install the ball joint, set it to the control arm and push the two mounting bolts. Do not bolt them. Insert the ball joint tail into the stub axle and then tighten the nut to the proper tightening torque. Tighten the mounting bolts of the ball joint to the control arm to the required torque. Install the wheel and ground the car.
