Yes we are looking at the entire support system right now. The shop doing the axle alignment stated the hangers are not operating properly and the springs are too long. This doesn't allow the hangers to move correctly. New springs are ordered and we will be installing them in a couple of weeks. I will check out the welds while I am under there tomorrow also. Thanks for pointing it out.
We are changing the springs out to a slightly more heavy duty in hopes to also raise the height a bit along with the shorter length should help as well. Maybe not a bunch but a bit. It will look a lot better with good steel hangers. I will post pictures when I get it all installed.
