I replaced the tailshaft bearing... i put a master kit in the 5spd, and i've ruled out the driveshaft because I took the driveshaft off and ran the trans threw the gears and I still got the vibration....this couldnt be a clutch issue could it? this is the first one i've ever installed...

it could very well be the harmonic balancer my car wouldvibrate bad at high speeds and turns out thats what it was

I'd agree with the u-joints/driveshaft. Change the u-joints or get a new driveshaft!

have you had the driveshaft balanced

its not the driveshaft, I took the driveshaft out and ran the trans threw the gears, it still vibrates and I doubt that its the harmonic balancer because I have not had a problem with that before, I just get the vibration now that the car is a 5spd not a AOD.... it must be the 5spd right? P.S. when i rebuilt the 90 T5 WC, but the cluster gear was messed up, so... I put a cluster gear from a 96 T5 in, and they both looked the same and everything same tooth count ect.... could this cause the vibration?

thanks alot!!!!
