also checked the shocks in the rear. bilstien 5100's, seem fine. is is possible the vibration is in the trans itself? its driving me nuts.

 

also it does not vibrate with the wheel soff the ground, if that helps!

 

Rear axle bearing? pinion angle? Carrier bearing?

 

all seem tight. no noises from the rear end at all. fresh fluid also. pinion angle hasnt changed.

 

Have you checked that flex-plate yet?

 

yup checked it today. no cracks in it. all the bolts were tight.

 

Man.....I had money riding on that....

 

im just hoping to find it soon it driving me nuts!!!! not so much the one at take off under hard accel. but the one at 52-55 mph on or off the throttle is really getting to me. dont get me wrong i want them both gone though.

 

Greased the slip yoke yet?
