How do you disconnect drive shaft on RWD truck 95 chevy?

There are two u-joints where you can disconnect the drive-line; one near the transmission and one near the rear-end. either one will work just to get it out of the way. But to remove it completely undo the four bolts on the rear u-joint and pull the drive-line away from the . But be careful if the front of the truck is up in the air or facing up your driveway you will spill most of the fluid. pay attention to where each bolt goes and which way the u-joint came apart and mark the top of the drive-shaft for reinstalation. the drive-shaft is a balanced piece and if you install any of it backwards from the way it came out you could end up blowing u-joints down the road or the drive line could bend and pull away from the transmission causing severe damage to the vehicle.
