    I have a vibration. Its not always there but when it is, it shows up while im accelerating and starts around 25 mph..I just replaced the rear ujoint and ever since then Ive had these vibs. I went under and tightened the bolts and its still there. Im not sure if its the ujoint tho because when i let off the gas the vibs stop. My bro said it could be the torque converter going bad but im not sure.. Anyone have any idea whats going on?

    did you replace it ?
    when the driveshaft was bolted back up to the yoke on the rear , was it
    greased ?
    see if there is playin the u joint , jack up the rear and put it in nuetral
    wiggle the driveshaft.

    Make sure you didn't over-tighten the bearing caps. That will make the bearings go south in a hurry and cause vibes.
