Gents:
I hate nylock nuts. They aren't worth the contents of my septic tank and should be banned from Planet Earth. Lock washers, threadlocker and nuts are the way to go. My trailer is a 2017 Load Rite and the spare tire bracket is mounted to the trailer frame with u-bolts and nylocks (I know, great security, all you need to steal a $250.00 mag wheel and tire is a $2.00 crescent wrench). In any event, I had put Threadlocker on the threads and then torqued the factory nylocks down to keep the spare tire in place. Despite this trailer having been on at max 10 trips, the nylocks were loose and the spare tire mount was bouncing around on the frame. Fork that.....I'm having a welder put a bead on each side of the spare tire bracket to hold it in place and have locking lug nuts to keep "honest" people from trying to steal the spare mag. Rant over, thank you very much.
