    When I am in overdrive and I take my foot off the accelerator there seems to be a lot of vibration. I don't notice this problem if I am not in overdrive. The tranny was rebuilt 6 months ago and the vibration has been a problem for a while. Any ideas would be great.

    yeah, Im sensing a drivehaft u-joint / pinion angle issue... thats exactly how my rig behaved after I'd lifted it but was using a lengthened pos factory shaft and bad pinion angles.

    Definitely sounds like a bad pinion angle. Put a cv shaft in the rear and that should do it with all the vibrations.

    Yup , fixed mine .

    All I have is a little tire noise and shakes and rattles expected from a 22 year old truck thats been wheeled . To me it rides smooth and comfy , but I am used to USED Chevy's anyway :D
