vibs over 50

[joellthomas]

92ludeS, this thang vibrates in 3 or 4 gear (auto) after 50 when the gas is smashed or the cruise is gassing. i shakes the s wheel and the dash?? ??? swapped tires front to back, and still it viberates. Where to look?

how's your alignment? tire and wheel balance? i would also check to see if you have any bulges in your tires. you can have a rear tire bulge and the vibration will feel like it's in the front of the car. Time to get new tires if so.

i have new tires, and it only vibs when i gives it gas over 50.

I'd go back to where you bought your tires and have them balanced. They shouldn't charge you anything if they are a reputable shop.

I'd also think about putting your car in the air and looking at your axles.

BTW: When my tire had a lump in it, it only vibrated at 65+..

it does't vib at all unless the accelerator is depressed, while in excess of 50 mph.

ok..... the only other thing i can think of is that you have a bad CV joint, but you would probably hear clunking while turning at full lock, and you haven't described that yet.

if that's the case, you are better off getting a whole new axle, since they are relatively cheap. if not, it's probably a problem with the wheels/tires.

Joel, I think I've experienced similar unexplainable vibration under hard acceleration AND my '90 Si shimmys a little bit under fully loaded suspension (going through a dip between hills in the road)... I just accept it as nothing extreme or threatening and enjoy my car...

prelewd dude, you da best, had it checked out and it was the cv. Boy it helps to give the mechanic some info. Drives smooth as silk now.
thanks
