The bumper on my truck tilts towards the left. After installing new leaf springs and equal tires, the problem still exists. The problem is that the frame is twisted towards the rear. At the cab back end, it is straight and level. My solution is to shim up the droopy side cross rail so when I install the bed sides it won't be noticed unless you look underneath. You can see from the attached pictures, to level the bumper, I had to drop down the right side. It looks like there still may be enough metal to drill new holes. I've never attempted to drill through that kind of steel. Can it be done with a good quality drill bit? If there is any other solution aside from taking it to a frame straightening shop, I'd like to hear.
The last two pics are the left side bolted up to be left as is.
