Good point, Davis.
I recently re-installed my Pull-Rite hitch to eliminate some clunking and found that I had not gotten a bracket tightly against the truck frame when I first installed it.
I used grade 8 bolts with grade 8 nuts and lockwashers. I read the article in FourWheeler magazine (I think it's the July or August issue) regarding LocTite vs. split-spring lock washers. That discussion prompted me to remove the lock washers and install LocTite.
I think that the LocTite will hold at least as well as the spring lock washers, plus it provides the additional benefit of preventing rust between the threads. Now, if I need to remove those bolts in the future, they won't be rusted tight. I intend to use "Liquid Locker" (LocTite) much more in the future.
