91 buick regal vibrates mid-high speeds	Sign In

year: 1991
make: buick
model: Regal custom
engine size: 3.8
mileage: currently sitting at 96813. odometer does not work though. Stopped working shortly after i bought it around january 2010.

while driving, i get up to just under 30mph and the car starts vibrating. its just a constant humming noise. just over 30mph it dies down a little and starts up again at about 38. At 45, it dies down again. At 60+ it starts back up. whenever i turn to the left a little the sound goes completely away and when i turn to the right it gets worse a lil. my stearing wheel is also a lil off. when im going strait, the stearing wheel is turned to the right about 10 degrees.

the issue started up right after my 2 right tires got slashed. i tried to pull out of my driveway not realizing my tires were flat and didnt get very far. I replaced the tires and it started doing this.

i took the car to a shop and they told me it was my wheel bearings. i ask a friend who was a mechanic and he said that if it were the wheel bearings, my car would be shaking rather than vibrating. i also dont think it is the wheel bearings cause the sound goes away when i turn.

hoping to get another opinion on it.

Generally wheel bearings will be worse or better with load like steering left and right going along,

Noise issue changing right to left defintly sounds like a bearing issue. If your wheel is off center you more then likely bent a component from impact. Whole front end should be inspected and then put on a allignment machine. If your toe is out it may be cupping your tires too and causing tire noise.

Fix whats obviously wrong first and go from there.
