How To Replace A Buick CV Joint

The CV joints are used to provide flexible power to your wheels. Deterioration is a natural part of the life of the CV joint, but replacement can easily be done in your garage.

Signs of a Bad CV Joint Include:

  • Strange noises while turning
  • Resistance or vibration in the steering wheel while turning
  • Weird noises during acceleration or deceleration
  • Visible damage to the CV boot

Instructions

  1. Park your Buick on a flat, level surface. Jack up the vehicle and make sure that the stands are placed in the proper position on the frame rail. Consult your owner’s manual for the proper placement. 
  2. Place some penetrating oil into the retaining bolts.
  3. Move brake lines and other parts out of the way of tools.
  4. In order to remove the axle, it helps to loosen the strut top mounts and the sway bar end link bushings for more room. Do not remove them.
  5. Take the wheel side axle mounting bolts off.
  6. Remove the wheel from the axle and keep the axle from dropping down or hanging by placing a prop underneath it. Letting it hang can damage oil seals.
  7. Pull or pry the axle from the transmission differential. Be careful you do not bend the axle seals or tear the oil seals.
  8. Take the new axle and transfer over any seals, ABS rings or any other parts that came off the old one.
  9. Move the new CV joint axle back in place. It should click when it's in the right spot.
  10. Use the right amount of torque to replace the axle bolts. Check its rotation and reassemble any other components you have dismantled.

Bring your Buick off the jack stands and take it for a test drive. Avoid traffic and make sure that everything is working properly. If you need help, contact your local dealership for assistance.
