me and Wild1 were test driving my car the other day, and he noticed as well as i did that my tranny vibrates a lot at high rpm at WOT. is this the u joint?? a friend of mine told me that this is easy and cheap fix, is this true?? thanks

 

did you even check the tranny mount???

 

before you replace the u joint check the 4 bolts at the end of your driveshaft to make sure they are tight. My friends mustang did the same thing and it was just a couple loose bolts on the driveshaft. If they are tight then its probably a bad u-joint

 

i have the energy suspension tranny mount, people says that it's bullet proof.

 

If everything checks out, your driveshaft may be out of balance. I know that would cause a vibration at high speeds.

 

that might be the cause. i will check it today, btw, will it cause vibration at high rpm's too??

I've got the same problem, here's a bump...

 

I had the same problem. I was getting a pretty strong vibration above 90mph. This is a very common problem with these years. There is even a technical service bulletin out on it. The fix is to get an aluminum driveshaft. That is what I did. Now its smooth as silk up to 150.

 

Is it a high speed or high RPM vibration? High speed would be either tires or driveshaft, high RPM would mean bad clutch/flywheel/pressure plate/pilot bearing/trans input shaft. What kind of clutch do you have?

 

Have you had the DS out of the car recently? If you have, you might try taking it loose from the rear and turning it 180 degrees.
That may help.

what the hell would that do???




check the tranny mount, balance the wheels, balance the d/s


in that order

 

Search around on the board, I have seen a few posts from people who have tried it and it worked.
Before you open your mouth and ACT like you know what you are talking about, do a search.

 

i have a high RPM vibrations......i have an A4 dude....a friend of mine said, it might be the U joint...
