I have a 01 ram 1500 5.2l 2wd. 1. At startup a sqeaul starts and continues for a good time. It gets louder with acceleration and quieter without. What could this be? What would be a good remedy? 2. I bought the truck used,and recently found out the bed is hiked up a little in the back left corner, and looks slanted from the back. Is there any way to level the bed out? Would i have to take it to a body shop?
