My G8 has 6100 miles. When I back out of my driveway and turn the wheel to the right, my car wants to pull to the left when I drive to work. After the car sits for a while , the car will drive straight. The tire pressures are all within a lb. Is the strut bearing moving, causing a pull? Or what?

I've noticed this every once in a while also. Kinda strange. I have 11,200 on mine.

Any one else have a similar issue?

Exactly what my car does! It seems as if my RR tire is a couple of pounds lighter then the other tires. The car tells me that they are all OK but when checking them manually the RR is a little lower (32 or so.). As the tires come up to temp, my car runs straight. Today I will add a little air to see if this helps, maybe the TMPS is not working properly in our cars? It seems that all these new features are great (but only when they work right).

Is the car pulling on or off the throttle? Could be the rear alignment...

Car pulls off throttle.

lol you got a FWD G8....torque steer is a bitch!

j/k lol

If I was to speculate, you would think it is a tire related concern.

I had the pleasure of spending a week with 3 of the top Pedders dealers in Australia, as well as 5 core people in the main office. Before the beers became overpowering (yes, the Aussie love our beer and hamburgers!) we talked extensively about product issues in Au. They have nearly 2 years more experience than us on the ZETA platform, plus collectively, have done a lot more installs than us, plus have dealt with a lot more problem cars than us. Here are 2 areas that they have found that may resolve drifting and pulling issues:

A. On the GTO forums, several years ago, I started a thread that discussed dynamic alignment issues. Turns out there are some dynamic alignment issues. What Pedders has found on a lot of is a dynamic problem with the rear. Due to an accumulative amount of non compliance with their bushes, they have found the thrust angles, which is the relationship between the the front and rear tires, can become excessive, thus causing drifts/pulls. How do they know? By process of elimination and this is how:
1. Accurate 4 wheel alignment
2. swapping tires
3. making major changes in caster bias with no difference
4. swapping out the bushes in the rear, problem fixed.

Now there have been a number of drift/pull situations on the G8 out there, but the problem is not bad enough to call it a pattern failure. But Pedders Au has fixed a couple of dozen of these problems by upgrading rear bushes. GM racing, found there were issues with the back end, especially toe changes, until they upgraded the rear bushings on the Racing Camaro that they are doing.

So this is something for all of you to think about.

B. Also, it is blatantly obvious that GM is having a bolt problem. How do I know? Because comparing OEM installs of the components at the factory from the first 888 vehicles, which I have done 2 of them, to say the last one that was the 15,000 or so, they are lockiting nearly everything. What has Pedders Au found? The upper inner forward rear control arm pivot is getting loose, and causing noises, but also causing changes to cambers. This is one of those parts that you really cannot see well without dissassembly. Pedders will soon come out with a permanent repair for this. The Beta testing parts have been done. Now it is a matter of production, and distribution.


So just a heads up on this. I will be making major posts very soon on this topic

My g8 had to have my barring changed and that corrected the pulling problem. The dealership 1st tried to contribute it to the slant in the road, tire pressure and finally they found out it was a barring.

There is so much compliance in the G8 OE bushes coupled with the w i d e g r e e n r a n g e on the GM alignment specs... The G8 should not pull when properly aligned. Have GM do a real alignment and toss out the green range with a tight spec alignment. Listen to Mike a.k.a. DMS and the pull should be gone.

What do you mean by "barring"
