You can do a quick check yourself. Just crawl under the TT, have someone hold a tape measure at a point on the coupler. Measure the front spring hanger on both sides of the TT, taking care to measure the same place on each hanger. You're creating a triangle with two equal sides. Then if they are the same, hook the tape on each front hanger and measure to the equalizer hanger then to the rear hanger. If anything seems out of the ordinary then the hangers need moved. If not them it's more than likely a bent axles. Your axles are attached to the springs in a predetermined location and can only be moved slightly, not enough to warrant alignment. The axle hangers have to be exact as the you can't move the axles on the springs enough to change anything. Your axles need to be squared to the front coupler as that is the point where the equal sided triangle starts. When alignment shops set your TT up for axle bending they set their lasers up with the starting point off the coupler.
