Play in my driveshaft

I am hearing what sounds like bearing noise from my front diff. my driveshaft doesn't have up-down, side-side play; instead I can spin my shaft about a quarter inch before tension, all u-joints good, just replaced bearings inner and outer. yoke nut is tight. and I already checked with the driveshaft dropped the yoke and pinion are spinning together so the play isn't in their spline. haven't opened the diff cover yet I intend to tomorrow. I put it on a snowbank to look at it and the stretch it put on the driveline seemed to stop the play. It has a 4 inch. suspension lift with pro-comp control arms and my bushings are bad.(procrastinating the replacement) also just had the driveshaft cv joint rebuilt and balanced.

question #1: should I have play in this way?

question#2: if not does it sound like it's my spider gears or ring and pinion?

question#3: could my bad bushings be trashing my driveline?

sorry it's a lot to read

First, you need to fill out your profile so we know what we're dealing with here. Second, that much rotational freedom in a driveshaft is perfectly normal. Its the gear backlash. If you have a problem it is something else. Have you pulled the driveshaft and driven to see if the noise goes away? Opening the diff and taking a look is never a bad thing either.
Thank you Dave Cole, Dynomax, Falken and all the Spec Class sponsors!!
