Vibration Question Again?

**Black87GT** · 06-09-2008, 08:10 PM

Ok, well just got home from the beach, and i noticed on the way there and the way back, that my car when used to vibrate at around 70-75 mph, it was really loud and a very bad vibration, you can feel it in the center consol, and transmission, and in the seat... NOT THE STEERING WHEEL... anyways as i was heading home, it got worse and worse... started doing it at like 70-75 like normal, so i stayed under that, and i had to keep going slower and slower the longer i drove... till it got down to doing it as slow as 55mph.... so wtf is going on.. do you guys still think its the driveshaft... i have one coming this week..

PLEASE!!! Let me know!!
thanks!

Automatic or Manual? If manual, does it vibrate in 4th gear at the same mph/rpms? I have a vibration at 75mph as well. I replaced the driveshaft and rebuilt the rear axle and still have the vibration. I will be swapping trannys next to see if it goes away. Good luck.

Have you checked out your wheel bearings?

well took it to a mech. he said he fixed it, that my driveshaft was barely hanging on.. and that fixed it to about 75... but till 75mph it STILL vibrates..
