The 99 TA has a strange vibration that, when it occurs , is typically from hard accelerating while turning slightly right (like getting onto a highway). I can't tell exactly where it's coming from. At first I thought it was from the L front wheel...but I can actually feel it under me too. It's related to acceleration. I'll get under it this weekend and check things out. Could it be a torque arm bushing, u-joint and/or transmission mount?

It was my transmission mount. I climbed under my car and sure enough it was broken. It was replaced and problem solved! Easy fix!

That inspires me....to crawl under it. Thanks!

The transmission mount was broken as well. I replaced it - and problem solved!
