Well, we do know a lot of them show up with collapsed strut mounts...so anything is possible I suppose.

Maybe the swaying side to side putting force on the rack since they are tied down?

That's a great thought, I know that back in the early 80's GM had a problem with a specific car line that was being damaged on long train rides because of the way they were chaining them down.

I have another follow-up regarding my car (see post #969 for my previous update). The dealer called and said the vibration was cured by replacing the engine mounts. According to the trouble-shooting procedure in TSB 10-03-09-001, the mounts become suspect after tires, wheels, and brakes have been ruled out. The only problem I have with this fix is that I thought mounts are a solution to excessive vibration caused by the AFM, which was not my issue. My car also vibrated with the AFM disengaged via manual transmission mode.

I am going to get the car now and go for a ride with the tech. I really hope this works.

I changed my lower control arms and radius rods (replacing the new stock bushings with Super Pro radius rod bushings from BMR) and re-aligned the front.

Took a total of two hours.

The casual rider in my car would not notice anything, but I, like most G8 owners, am not a casual rider. I love driving and the feeling of being immersed in the vehicle.

The mounts will do fine, at least for now. Given what has happened, I am obsessing about every little noise and shake; if you look for trouble, you often find it. The big test will be when I do my next tire rotation. Rotations seem to upset the machine's delicate balance.

I have to give a credit to the Coleman GMC service department for their patience and willingness to get things right.

That's great news. The improved engine mounts are designed to do just that...mask normal engine vibrations so they don't transmit though the frame/steering rack/etc causing unwanted vibrations and other harmonic pulsations. As an FYI, my car still has the original transmission mount(s). It is my understanding that GM also came out with an improved trans mount to better dampen/isolate both normal vibrations emanating from the trans/engine at that subframe connecting point + dampen/isolate a mildly unbalanced driveshaft. I still get the minor pulsating vibrating that comes in and out at highway speeds - if I really wanted to go through the hassle and potential cost of upgrading the trans mount, I guess I'd do that too but my biggest issue was the steering wheel vibration and like I said before, the revised new engine mounts did the trick for me as well. At my next oil change, I'll ask the SA how much it would cost to replace the trans mount. If it's not terribly expensive, I may do it.

@TheStevo, I’m sorry to read about your vehicle concerns. I’m curious if you have any further updates to share; were you able to get the vehicle into the dealership and things of that nature.

Just put on another set of tires for the winter. No shakes. Appears the deal was entirely balance and related.

Sorry to revive this notorious old thread.

New tires and a road force balancing has eliminated 90% of the steering wheel shake I had at 60-70 mph.

After 4 years, two sets of wheels and tires, the full dealer TSB for this, etc; I finally have some resolution.

Okay so I just got my '08 White Hot G8 GT yesterday and today I noticed that the front end shakes when turning left and right and when I brake it shakes pretty good then too. I'm sure the braking issue is from the rotors but what would cause the shake only when turning?
