A big clunk going into reverse.

As the title saids, I have a very loud hard clunk when shifting into reverse sometimes ,is this the u- joints starting to go bad? The tranny is a E4OD.

I had this on my old 86 with a C6 and never figured it out. I was told Ujoints might be the cause, but never verified this.

It's time for new u-joints, the old ones are history.

Most likely u-joints, jack the back of the truck up,and wiggle the driveshaft to see if you can see where the play is.

My 96 f-150 does the same thing. Even when the drive-train is switching direction, reverse to drive, then i get on the gas and hear it. from park to reverse as well. I've always been told it was in my transfer case, but theres play in my driveshaft. I've never really been to worried about it. I'm gonna rebuld my motor first lol.
