I had a new Dexter 3500# full axle replaced in the field (campground) on a 5500 lb tandem travel trailer. I am now home 6-8 hours away from the installers and I would not go back to them anyway. When I crawled under it today to look at the job they did, I noticed that the guys who installed it did not get the axle 90 degrees square after welding it in place. Meaning the bow in the axle is not top dead center when comparing it to the factory installed one. It is off just enough to notice, maybe 5 degrees, eyeballing it. Is that a big deal? Do I need to have it re-installed?
