Check the ladder bar brackets on the rear housing. Sometimes the holes will enlongate (oval) from a loose bolt condition. This will allow the preload to change at the "hit". If this is the case, simply make some sleves about 3/8" long that fit the bolt fairly tight with about a .250 wall thickness. Weld (TIG) them to the ladder bar brackets (one for each hole, 8 total). Take the time to determine the correct location of the sleves to be welded in place. You can use the undamaged bracket to comfirm the proper hole location. Use a pair of dividers (dividers: as in a device/tool used to draw a circle, only using the points to determine location instead of a tape measure). After the fix, reset the preload and confirm at the track (compare tire temps after the burnout).
There could be a shock issue, or a tire issue but these things usually will cause a slight drift in one direction and not a consistant hard move. However, you will need to make shock adjustments a few times each season. This will compensate for normal wear of the shock, most of which happens in the trailer during transport.
