I have realy hammered on this front end before, and had never broken a bir. I tore up my 5.71s on fri. of a big ride. I took my old 4.11s thirds and threw them in. I had run the locker in the rear before. This time i decided to put the locker in the front to help turning, and it did. I have the turning bump stops out a good bit. Thats how i always figgerd i didn't break them.

I was just thinking that the locker starting to spin and then catching mite be what was causing me these problems.

If you broke a Bir. you will probly know it. The tire will lockup and be hard to turn.
