Just a quick follow up, I did take my bolts out today and added locktite, but on my frame the nut is welded to the bracket that is welded to the axle assy.
Also can't use Grade 8s though, since these are (metric) M12 bolts. Mine were Class 10.9 which is strong enough. (similar to Grade 8 SAE)
PS. Thanks to the TS because mine were LOOSE
PS II. I love hanging out under the RV, I really do. Shouldve gone to school to be a mechanic
