Clunking/chirping sound under my truck

Alright fellow mopar peeps. 2003 1500 4x4 hemi. I have a chirping sound going down the road. If I give it gas or hit the brakes hard the sound goes away. I also acquired a vibration at low speeds. And some clunking when I go in and out of gear. All of which sounds like u-joints but they seem tight. However, when i twist the driveshaft in neutral i have about 1/2-3/4" play in the rear end....

Check the shaft remove it if you have to. The noises you describe loaded accel and shaft loaded decel make it sound like a joint

I agree. I feel like a dummy because it's so classic for a u joint. Other than the chirping. That's weird. I dont think I've ever heard this noise come from a vehicle

A dry bearing cup will make a squeaking sound on a U joint.

I think this weekend I'm gonna change out the u joints anyway but I'm more concerned that it might be a rear end issue. However, it's almost 224k miles and I dont believe the u joints have ever been changed so I'm gonna start there

Look for rust dust around the cups

I'm sure you guys are right. If you wrote o book describing bad u joint symptoms this would be it....lol. I was embarrassed to even post this but it was weird that there wasnt play in the u joint. I figured it would really loose but I'm gonna change both this weekend

Well, apparently that wasnt the issue. Although the chirping sound seems to have disappeared. When I pulled the u joints out they actually looked pretty good. I was impressed for having 224k miles. However, I'm thinking it has something to do with the rear end possibly. Im still getting a pretty bad clunk at low speed (15-25 mph) and if I let off the gas and level off at about 70 I get a pretty bad shimmy. How much play should the driveshaft have?
