I had a crack in my engine crossmember on the right side (typical). When I had the engine out, I had my uncle weld the top of it, not the greatest work but it has held up. I wanted to get the bottom side welded and get the steering box reinforced. So I had a local off road shop do this for me, turned out great. I also replaced the steering box while it was out, old one was leaking, and a little sloppy.

I really did not want to spend the money on this right now, but this is insurance on this area which is common to cracking especially with bigger tires. So with the bolt in brace and the weld in done, this area is plenty stout. Even the guy at the off road shop said this is bulletproof even if I had 44's on this thing.
