Happens to me as well, Sonoran Steel lift. I've adjusted the Panhard rod some to scoot the axle over to the passenger side, but I don'
t want to get too uncentered. But it still can touch if I get into a full flex. And once it catches a little - the driveshaft weight bends the skid outward so it touches easier next time.

I was out wheeling this weekend and had it happening. Makes a HORRIBLE noise, but I'm sort of used to it now, not terrified like the first time I ever heard it. WTF!!?!?!?!

I bent it back *again*. Pried it back enough to dent the side of the tank in a tiny bit as well. And folded the little sideways lip that had developed on the top edge. Fingers crossed for next time...
