1998 4.0L---Let's talk exhaust mounting

So, I've been fighting my exhaust pipe position for a while. Collective trail damage over the years has bent and repositioned the pipe and its mounts. It's knocking right there at the transmission mount because the pipe is resting on the crossmember. I've tried everything to reposition the pipe to get it up off that, to no avail. It sags back down after a bit of driving and the knock returns.

I replaced that little square rubber insulator inside the trans mount, that the exhaust support bar slides into (what a crappy design). I've replaced the trans mount, the crossmember, and the entire front pipe. Also replaced the hanger by the axle. (The rearmost one is gone--I mean the #2 hanger.) A lot of this stuff was damaged or rusted, so replacing was mostly general maintenance--not a case of throwing parts at it to fix the knock. But the pipe still sits too low there.

SO, my question is, are any others dealing with this same problem, and have you found a way to resolve it?

Thanks,

Chris
