Pontiac G8 ball joint problems

Filed Apr 23, 2017 · Suspension · 67,000 miles · IN

While driving the vehicle the front suspension shakes and clunks while driving at any speed. Both ball joins have tears in the rubber boots which I'm sure causes water and road debre to enter ball joint and corrode. This is a huge safety concern for me and when a ball joint lets go it can be fatal sending the car in any unchosen direction. Please note this is happening to every single pontiac g8 owner I've come across. This is life threatening, ball joint lets go on the highway and the car will go into a roll. Thank you for your time and consideration

While making a some what sharp turn to the left on a freeway at approx 60 miles per hour (legal speed for situation) noted vibration in right front suspension. It felt like the tire was attempting to come off the rim.. I backed off and the problem dissipated. I took the car to the dealership and it was determined that the right front rear lower support arm had severe play in the ball joint. The same issue is present with less wear in the front left lower control arm. The play has caused premature wear in the right front tire. Tires have been rotated regularly at the dealership at suggested 5,000 mile time frame. The dealership did not detect any problem in the suspension during any of the scheduled maintenances. Considering the mileage on the car there is unreasonable wear occurring in suspension part creating a dangerous situation.

This car clearly has lca (lower control arm) issues. I had mine replaced 10k miles ago. They are noisy again. With just a little research you will find that around 80% of g8 owners have front end suspension issues. Why isn't gm recalling this?

The car shakes when turning slightly to the left at approximately 50 MPH. I came to find out from a garage that the lf control arm needs to be replaced. You can actually wiggle the tire from left to right when it is up on a jack. Two years ago, the right side had the same problem and was replaced.

I recently encountered a clunking/knocking noise in the front drivers side of the vehicle when going over small bumps, as well as severe shaking/vibration when braking and steering. This made it difficult to control the vehicle, especially at higher speeds and on freeway curves. Since the vehicle is no longer under warranty, I took the vehicle to a trusted local mechanic. They informed me that the front lower control arms needed replacement. After doing some additional research, it appears there were both a service bulletin and a customer satisfaction campaign for issues with the g8 suspension, specifically the lower control arms. These issues included problems with the rubber boot over the front end lower control arm ball joint, which may become dislodged or torn compromising the seal. Moisture inside the ball joint seal could cause corrosion, shortening the service life of the lower control arm. My local mechanic completed the repairs and also did a front-end alignment. They supplied me with the defective lower control arms, which showed evidence of the torn rubber boot on both arms and corrosion. After contacting with gms customer service, they are not even interested in discussing further because I did not take it to a dealership (who charge over $1,000 for these repairs). I even offered to send them the defective parts, but they weren't interested. They used the excuse that the recall only included certain VIN's and mine wasn't included, yet I had the same exact part failure and symptoms as other vehicles included in the recall.
