I've been running lockers front and rear for about two years now on 31 inch Swampers. I *really* like it. Sure, I have no ground clearance, but I've got tons of traction, so as long as I can get one of my go cart Swampers onto something, I can scrape my way up and over. I have had zero problems with breakage, and I've been heavy on the throttle at times(as slow as possible, as fast as neccesary). I've even been in the classic birf breakage positions(downhill, turned to lock, reversing with all the weight on the front end). It took me some practice, but I can get the front to unlock. I've found that if you bump the throttle while turned, you can get it to ratchet around the turns. I've run it at Tellico several times with the just the rear locker, and having the front locker really did make a lot of difference. You won't be disapointed with just a rear locker, but locked at both ends is just insane. I can't hang with the tube buggys on 38's and up, but I do surprise a lot of people. This is all on my '71 40(w/ '77 birfs), so I would think your mini would be just fine locked up front. Oh, and power steering is for sissys.
