I had an earlier TT axle alignment done by Badger Utility in Wisconsin. It's a place that repairs big rig trailers. Their method of aligning the travel trailer with leaf springs is to loosen the U-bolts that hold the axle/spring assembly together and move it as needed for alignment. There is room in that assembly for about a 1/4 inch of movement total. If it needs to go beyond that it has to be bent or the spring mounting tabs cut off and relocated.
