Pontiac G8 GT steering wheel vibration/shimmy at highway speeds

[NissanMaxx]

Same thing happened to me, all I did was a wheel alignment and it fixed the problem. I don’t know if it’ll work for you because it sounds like something else but one way to check is to see if your tires are getting ruined at the edges. Oh my bad you alrea

Suspension components do not cause vibrations at higher speeds, only rotating components do._x000D_

I would start with rebalancing those tires. What type of wheel weights are being used to ‘balance’ your wheels and tires?_x000D_

Did you try to rotate your tires?

A+ on Dreamers post. Do you have another set of wheels to put_x000D_
on the car to see if the issue goes away or changes?

You may have to have them road force balanced. Some cars that’s the only way to get rid of a tire vibration which this sounds like to me. I know some of our Cadillac’s are picky and will have a vibration no matter how many times you do a wheel balance. On

The new Nitto Invos that only have 5,000 miles have been road force balanced to no avail.

5 inches of wheel weights is alot of weight to compensate for dynamic balancing if those weights were close to edge of the rims._x000D_

How many ounces was that line of weights and what type of weights were used?

As stated suspension parts do not cause vibrations rotating assemblies do.

Please dont forget to change the traffic light to green so it updates our database.

I was going to suggest that you may have weak struts, but it looks like you have addressed that issue more than once.

I’m still waiting for the new RE11’s to arrive.

Thanks for the update and the fix.
