vibration

[Dustinh]

Hey guys and gals just joined. Have an 02 Tahoe L's 4x4 with keys and spacers on 33's and 20x12's. My wife hit a pothole on the interstate and have not been able to get rid the vibration since. Before that I had just changed the idler arm and pitman arm and the tie rod ends. Had the alignment done and tires balanced. After the fact I had to have the alignment done tires rebalanced at rimz one on their road force balancer and I've replaced the passenger front hub assembly. Can someone shed some insight to my problem? Its fine in town but 65+ its bad. Do I need to replace the idler and pitman again? Thanks for your help in advance

That's a strange issue. Have you swapped tires from front to back and the vibration still exist?

Rim bent maybe. Even slightly will cause a vibration or you have a tire with a hop in it. It will still balance but will vibrate at high speed.

Could be this. I had a tire go bad once where it balanced fine, but would vibrate like hell only SOMETIMES while driving. It ended up being something about the internal radial belting in the tire was damaged. The problem followed whichever location I mounted that particular tire on the vehicle. Since the rim didn't appear to be damaged, I replaced the tire and the problem was solved. This could make sense in your situation, too, since the tire suffered through the pothole or whatever you said your wife hit on the highway.

Yeah I've also had a tire blow a belt band inside the tire causing vibrations and ultimately dumped the tire for a new one.
