I just installed an Aussie Locker into my dana 30, and I'm having a little problem. I have a non-disco front, did the install, and found that the locker is not disengaging in 2wd. I tried to get it to unlock on dry pavement, no throttle, and turning. Steering feels awfully heavy! All my specs. were in acceptable parameters when I assembled it. Does the locker need to break in, for a couple of days? I had a lunch box in the rear of a Sami before, but never in the front of anything. I thought this locker would be fairly transparent in 2wd.
