I spent some time underneath it replacing body mounts and noticed that the springs tended to have some bias toward one side. I think that if I loosen the u bolts and suspend the axle I may be able to center it some.
I measured from the body and from the frame and really didn't see the anything but that it is off. Original frame and body. I did install the OME springs and new OME shackles and bushings about 8 years ago. It's probably not a new thing but want to correct it.
I was looking at the outside wall behind my driver side rear tire and saw scuff marks. I got to measuring and found out my passenger tire is an inch and a half farther out than my driver's side. I see no obvious reason why this is. OME springs and shackles. I'll get some pictures.
