What type of terrain do you normally wheel on? Do you have similar issues or does this seem to be a Moab slick rock issue?
The Moab Rim trail is 100% slick rock to the rim and I would assume puts a ton of stress on everything because you are climbing, turning tight with the weight shifted over one front tire. Do you get to the point that you physically can't turn the wheel? Mine gets to the point that it feels like the wheel is locked on occasion.
With a front locker you really need to be as beefy as possible on the rocks. Stock studs may not be enough for your setup. 4 or 5 ARP studs may be sufficient. My tires are smaller so I can't tell you what the limit is from experience.
