    hey guys after i read some of the post, just wonder how to see if there is play on the rear end? like spinning the shaft? i put my car up today to see whats up with my DS cause i got some vibration and low speeds and then over 80-90mph will get very bad, i did spin the drive shaft and ill give it about half inch moved and the wheels didnt spin, and when i also engage my clutch i hear some banging sounds like if my ds is trying to catch or something, im kinda starting to think its my rear end.

    I am wondering if that isn't from the u-joints. I have had u-joints cause vibration on my GM vehicles and changed them out myself. Have avoided looking at the Supra system simply because they are more complex than the simple ones found on other cars.

    (not sure if I am correct on this, but I thought there were more u-joints on a Supra)

    After a day on the Dyno I found my car was trying to revert to kit form, after that I loctited EVERYTHING, 262 in steel/iron and 242 in Aluminium.

    Um, driveshafts are not 'floppable'... I'd go to a driveline specialty shop and have it checked for straightness and if it passes have it balanced.
