Yeah, you really have to watch out for those cattle guards.

I wouldn't have been surprised if you had said you had welded up just about every part possible on your X. You are definitely not shy about challenging obstacles!
I was quoted $500 for the labor from my mechanic for the one side and today they said they could do both for that price. Since there is no guaranty that the $50 weld job is going to hold and because of the new ball joints and bushings you and Bobby mentioned, I think I will go ahead and get the new LCAs from Courtesy Parts. And it only makes sense to have a reinforcement plate done at the same time. Now I need to do some research to find someone that will do both.
Update: I talked to my muffler guy and he said he doesn't weld structural parts. But when he looked at the cracks, he said no problem since they were not that significant. I may do that as a bandaid until after Big Bear and then get it taken care of permanently. Might be time to get a new Flowmaster.
