Slight vibration on the floor at higher speeds.

Slight vibration on the floor at higher speeds.
Hi all,
I've had my 07 g couple 5at with performance and areo pkg since last august. I bought it from a dealer in very good condition and no accidents. Recently I've been having problems with it. I stored it over the winter (3 months). When i started driving it again, i heard a noise from the back and turned out it was the rear bearing. So after a hard time finding the bearing, I changed it. Then I felt the floor vibrate and a slight noise. It got a bit worse. I checked the bearings and they were find. Took my car to a shop and they said it was uneven wear from my tire. So I got a set of new tires and an alignment. I still feel a vibration over ~80 km/h and it makes the same sound at ~140km/h. Could this be since I have the low profile tires and suspension pkg? Or any other ideas?

Welcome to DRIVER! If you bought quality tires and your alignment/balance is correct you shouldn't have vibration issues at any speed. I'd begin by going back and having the tire shop re-balance your new tires. While they're doing so have them check those tires for an "Out of Round" issue.

I don't know how you stored if but if you literally just parked it then the tires probably have a flat spot, but your new tires should have fixed that, unless they were improperly balanced to begin with.
Another thing is that your wheel bearings could have simply rusted over since it wasn't driven every day. When you drive your car every day, it helps prevent things from building up on the rotating parts, so when you don't drive your car for a while things that normally wouldn't be an issue start coming up.

Usually a floor/seat vibration is from the rear while a steering wheel vibration originates from the front. This is not always the case but it is generally the way it turns out. If it is not a tire/rim/alignment issue then you might have a bad strut or hub/bearing/axle. Sorry I know that is a very non-specific answer but it is difficult to diagnose a car without seeing/hearing it in person (unless of course it's a common and well known issue).
Best of luck,

After storing mine last winter I had a a stuck piston on my rear right brake caliper. It caused alot of vibration and "womping". Also, my wheel on that corner was getting really hot. Got a new caliper and problem was fixed. Feel that wheel and see if it's warmer than the rest after a 10-15 min drive.
I'm talkin about that corner was getting so hot that when I removed the wheel the lugnuts were burning my hand.

I had a similar vibration but it was high frequency and I heard it more than felt it. It was the front tires. Feathered/cupped. New tires and noise/vibration gone. But, if that didn't work for you it must be the new tires or something else. I'd look at the brakes as mentioned above. A warped rotor could do the same thing.
