Thanks for your responses. I'm not sure if the truck has been lowered but it definitely has been through some stress on the rear. When I first got the truck the rear was sagging. When I inspected the rear-end I realized that the springs had 2x4s running through it presumably to help with the sagging. Also the factory shocks were replaced with air shocks. Everything should be back to normal now as I have replaced the rear coil springs with new ones and installed the proper rear shocks. I would post photos but as it so happens, my camera is out of commission. But anyway, I believe the rear-end is back to normal so the replacing of these bushings should be a simple fix. Thanks a lot!
