Ya, and that is not happening. The second Pontiac shop said they checked the tire balancing and you can see they did, becasue some weights look new. And you feel no vibrations. It is a specific feeling only when taking right bends at highway speeds. Not turning right at intersections or anything like that... It is a strange feeling to describe, and I have never had any car with a similar symptom... It just feels like the steering is very very tuchy when sweeping right. You turn the wheel the slightest touch and it just want to go right (right now)...
I would do the tire rotation like Toast recommended for starters, then go from there. The hub assemblies when starting to fail will sing. The frequency of the singing will change when making those long gradual turns due to loading/unloading of the wheel bearing. Your SLE does not have Stabilitrak. It may, or may not have Magnasteer. Check the RPO codes on the spare tire cover.
Thanks.. I will rotate the tires tonight...What do you mean by the codes on the spare tire?
There is a list of RPO codes on the spare tire cover. Basically, the codes indicate all equipment, options on your particular car when it rolled out of the plant. As an example, NW9 is Traction Control. Look in Techinfo, I think the RPO codes are listed there.
