I ran my original, balding, stock BFGs at Moab last week and have for the last 6 trips. I've had no tie rod issues. I've debated for a long time about going to 37s. I've decided I'm going to do it to offset the clearance I've lost with my new underbody protection. That one inch makes a difference. I'm also going to go with (I think) the BFG MTs. I was skeptical about the MTs since the ATs work so well. However, I've seen so many people crawl rocks, walls, and everything else with the MTs that I'm ready to give them a try.
I do think that keeping everything "stock" (except tie rods) is the way to mimimize damage/stress. The H3s that busted diffs in Moab had larger-than-stock tires. That said, it's not keeping me from going to 37s. I don't think it's going to be significantly more risky to do that, but I'm getting the Fabtech tie rods to compensate.

I'm doubting the tires had a tremendous amount to do with the H3's diffs. It's likely the same would have occured with stockers with good traction the way it sounds like it occured.
The picture I saw of the H3 diff backs up the descriptions. A few teeth are missing off the ring gear which makes it appear that the truck was stationary and trying to move it's weight. The only extra thing that the 35s were providing for it at that time was a better contact patch. </div></BLOCKQUOTE>

So what makes the teeth fail in such a circumstance? Is is it simply gear teeth that aren't strong/big enough or something else? I.e., what could be changed to prevent this in the future?
