Hey Everyone,
So a while back I posted about vibrations I was feeling in my seat while driving on the highway 70 MPH +. I got my tires road force balanced and it solved the issue. I just got back from a weeks long vacation in Maine. Before I left I had the tires balanced and rotated to ensure a smooth ride up.
While driving up my seat and the entire cabin shook when I exceeded 70 MPH, it got worse and worse the faster I went. The steering wheel didn't shake at all. I figured the tech balancing the tires did a bad job so I visited the BJ's in Portland. They re-balanced all my tires, I was present when the job was being done and noticed they were all out of balance.
The BJ's tech said it look like the shop that did the balancing over balanced each wheel. As soon as I hit the highway the same thing happened, shaking above 70MPH. At this point I determined it was probably a bent wheel. I visited a local wheel repair shop, they checked out both my rear wheels since the steering wheel wasn't shaking I didn't bother checking the front ones.
It turns out both rear wheels are ever so slightly bent, they attempted the straighten out the more bent one. They tech doing the job said he was surprised I even feel anything at all. So I had my hopes up that the problem would be fixed but as soon as I hit the road the same shaking returned. At this point I have no idea what's wrong with my car. I'm thinking of buying 4 new wheels, the car came from the factory with low profile 18 inch wheels which have been a curse.
Any ideas what could be causing the issue? Bent Axle?
A few more details about my car:
Toyo Proxes 4 Plus - Ultra high performance tires (Maybe contribute to harsh ride?) 20K miles on them
Installed thicker 20mm rear sway bar 6 months ago (But I never had shaking until now)
Installed front tower strut bar 6 months ago
-Thanks!
