Clunk Clunk
If i hold one of my rear tires and pull back and forth it makes a clunking noise, and when i go over a bump, it makes the same noise. The rear end is moving when i push and pull on it. I checked the lug nuts for tightness, and they are. What could be making it move like that?
yeah that movement might be due to the panahard bar, or maybe that side's axle is moving in and out, or even both. but if the whole rear end is moving definitely look into the panhard bar.
look on this page at the pic of the rear end. Its the bar that goes from the rear axel over to the body goin from left to right.Its black

Agood here,
Its not the panhard, its your axles that have play in them near the carrier pin and axle c-clip area. As the carrier pin ages, more play develops in the floating c-clip axle design and the lateral knock becomes more previlant. Even with a new carrier/carrier pin, you will still get a lateral knock or clunck on a 10-bolt c-clip style rearend.

the rear end is moving from side to side, atleast from what i can tell, it moves the same amount with i pull on either tire. Still need to know if the panhard bar is interchangeable

Yes they are interchangeable. Even a 4th gen one would work, V6 or V8 - they are all the same.

My panhard rod made a lot of noises but that is because I had the rod end on the wrong side. I took it off and flipped it around and everything went away.

Where is it better to place a rod-end (if using bar with one end bushed and another "joint-type")? Attached to body or better to the axle?
