Re: How do you keep leaf springs in line?
I have seen this to be more of a problem with the leafs that have graphite pads than those that do not. Couple things, the u-bolts should be torqued to 50 ft lbs when the threads are clean and oiled. The king pin should also be wrenched down very tight as well. I have had this occur a few times and used a BFH on the trail to knock it back in line. I didn't have Jimmie available to yell at them for me! Another way that works is to get a 2" square u-bolt from the hardware store, one that has a flat plate on top. With the leafs in line, put the u-bolt on near the end of the offending leaf, with the threaded ends up. Slip the plate over the top, and here is the trick, drop some very stout springs over the threaded ends and tighten them down some with the nuts to provide tension. To keep it in place, I have tack welded it to the leaf on the bottom, a couple tacks near the end won't hurt the spring. These are manufactured and available from spring shops, but most of the time they are flat on the bottom and riveted in place. Sometimes they are just legs that stick up from the sides, take a look at your factory overloads, same thing.
