Ok think ive found the problem. The damn inner wheel bearing is gone on the passanger side. Takes a lot to move the tire but once i got the jeep rocking good by hand you can see it move all over.
On my Scrambler I had a Waggy Dana 44, spring under and over with 36" tire and had bad D-wobs, tried all the things you did to no avail I ended up having to install a power assisted steering ram/stabilizer to resolve my death wobs. See link above for pricing, totally worth it, fixes the issue and adds more power to your tie rod which take load off the steering box, frame etc. Hopefully this works for you!
