3000gt vibrates randomly

[X2Xtreme360]

Every once in a while my car will vibrate. It doesn't really do it under any certain circumstances, it will do it for 5 minutes and then everything will be smooth again. It almost feels as if the tires were not alligned, it only does it at high speeds but like I said, not very often. (I'm sure it does it at lower speeds but it's more noticable at higher speeds.) Any ideas?

where does the vibration come from? can you be more specific?

you could always get your tires balanced. but before i suggest that, give us more details. it could be a loose part vibrating at that high speed.

Honestly, I can't think of any other way to explain it, lol. It's like a steering wheel vibration, but also in the gas pedal. My girlfriend can feel it in the passenger seat when it happens too, so I guess it all over. Just as it would do if the tires were inbalanced.

did you check for ice in the the inner "lip" of your wheels? happened to me once before.

[X2Xtreme360]

Well it happens when theres no snow on the road. Plus if it were ice I would think it would happen all the time rather than on or off like it does. I dunno I'm stumped. Everything that I've ever driven vibrates either constantly, or never at all.

have you checked you wheel bearings..cuz that happened to my once before and it turned out it was one of my rear wheel bearings..jack up your car and see if any of your tires have to much play in them..
