ok so i got an alignment done few weeks back, and i felt a vibration coming from the driver side wheel. took the car back but the mechanic couldnt replicate the vibration. it comes and goes. usually starts just as i accelerate but then goes away. just wanted to see if anyone else has this problem before i take it to a different mechanic.

 

Give it a week or two. Depending on how bad your old alignment was, your tire may have been worn unevenly compared to how it is oriented now.

It may rectify itself as you drive and the tire breaks into its new wear pattern.

Or, there may be a more serious issue. Chances are that if there is, it will get less sporadic and happen often enough that you can take it to a mechanic and replicate it.

 

Try getting your wheel balance checked. I bought mine and the thing would vibrate like a bastard at 70 and then go away at 75 but as soon as I came off the throttle it would vibrate like hell. I had my wheels checked and they were SCARY off balance. The backs were off by like 3 or 4 ounces or some crazy chit like that. $40 later all wheels were balanced and the car is a friggin dream to drive now!
