Ag 400 suspension

I can't tell in the pic, but it looks like the bottom saddle is centered but the top bracket is tweaked a little. If the frame had alot of rot behind the bracket when you took the old one off that will do it. I really think it isn't anything to worry about if everything else checks out.

 

Yeah you could be right. Truck has over million miles so things could be worn out.

 

The top plate is slightly tweaked the more I look at it. There was some rust underneath the old ones when I took them off. Yeah I'm not to worried about it. The picture the OP posted sure looks like something going on.
