just curious, do you know if it's the studs or nuts working looses, or are the studs actually stretching? I have 37's now with hydro assist and mine come loose everytime i go wheeling. i'm constantly checking them.
The ARP's aren't suppose to stretch so it's either the nuts (I bought new ones from Marlin for the next go around) or the knuckle threads stripping. My passenger knuckle has 2 stripped holes. I've got spare knuckles that will get Longfield 5th studs to them. My buddy always fought loose arms until he added the 5th studs. I'm hoping that takes care of my problem as well.
