ok heres the whole story. i had a small vibration that started @90mph. its speed related NOT RPM. so the first thing i do is get my tires balanced. vib still there. so im thinking its ujoint or tranny mount. i have new u joints put in and i jack up the tranny and put in the new mount. now the vibration is 10x's worse. so i put the stock tranny mount back in. still 10x's worse. i pull the alluminum drive shaft and take it to get balanced. i put it back in. no luck. i turn the drive shaft 90 degrees then 180. still the vib is there 10x's worse. im running out of options so i check the motor mounts the upper and lower control arms, everything looks fine. so now im thinking when i jacked up the tranny i must have bent something like the tranny shaft. what do you all think?
