Car Vibration Problems.

[monsterhunter]

Wel today i decided to go out and drive with my bro(still on permit) and i was driving around all day and didnt really feel anything alittle vibration that has always been in the wheel thats it. But today as i drove around more, it started to get WAY worse, as i drove. At first i thought it was a tire, was going to check as soon as i got the chance, but then as i had to brake for a car in front of me i the vibration just went away. so i didnt pull over, i got back up to speed (around 30 mph when i first notice it, i was dong 40mph) when ever i got back hard on the throttle it would go away, if i normally accelerated it would be there and slowly get worse. Also as i drove and went to go around a corner it would go away, I havnt gotten a chance to look at it yet, im going to do that tomorrow. but any ideas would help out GREATLY

Thanks,
Jay.
