I have a shake from 50-70ish in my steering wheel. I bought wheels and had them balanced 2x. The stock wheels were doing this as well. What else could be making it shake? Its fine around town and only shakes on the highway.
I doubt if that's the issue since he said he balanced his wheels. I would look at the front steering shock (stabilizer shock?). I would check out or have checked out all steering components if not the shock. Sounds dangerous.
New lugs on and still a shake. My tires are showing some shock wear so shocks are getting replaced tommorow. Ill prob go back and verify the balance is straight also. Next would be the alignment and hope fir the best
