i noticed a vibration somewhere in my drivetrain from about 90mph-125mph anything above that speed and there is no vibration at all.... what could cause this ?
I did a search and most indicated the driveshaft as the problem source... I doubt that this is the case here, since the vibration is gone after 125mph.... do you think my poly tranmission mount could cause that problem ? Maybe even the Borla pipe that is almost touching something ? Weird thing is that its only from 90-125..

Since you had your driveshaft out recently, I would go ahead and disconnect and rotate it 180 degrees and bolt it up again. Then run the test again. As for being wierd not really , as another vibration of a different freq could cancel it.

If it still vibrates after the 180 degree turn, then turn it one more time 90 degrees. If you still feel vibration, then maybe wheel balance.

Won't be abe to do a 90 , due to the fact the driline can only be mounted in two positions

Ahhh...I just crossed over from Stangland to the world of bowties, so excuse my post. I need to erase my mind of Ford tech on this board. :oops:
