I am assuming you have radials. Radials need a lot less toe in than bias. We went to almost zero toe in on our trucks when we switched to radials about 40 years ago. General Brake in San Antonio used to do aliments for us, but we use an old fashioned Wheel a Matic gauge. General brake has anchors in their floor to bend I beam axles. We have had some I beam as well as trailer axles bent there. We have taken axles out and bent them with our hydraulic press. 25,000 trailer axles yield at 38 tons. They are still in business, but I'm not sure if they have any competent people down thee. Also radials need more caster. Since everything we do is I beam we call it king pin inclination instead of caster. That is also simple to measure with a magnetic gauge on an I beam. Over the years we have had a few aliments done with laser setups, but we always wound up re-doing them. I really don't have anyone at the shop that understands alignment any more. Where did you get an alignment. I hope it wasn't a deal like my daughter fell into when she was in college in Seguin between 1990 and 1994, I got my BBA in accounting and pre law down there in the 1960's. She drove a 71 AMC Hornet and was having problems so I told her to take it to an old AMC dealer in New Braunfels. I didn't know they had sold out. They charged her big bucks to run diagnostics and found nothing. I'm not sure where they found a diagnostics port. I drove there and filed the points and the next time she came home I installed a new set of points.
