I getting death wobble I added 1" shackles. Now my caster is around 10. I know it needs to be around 7. Can to much caster cause death wobble? The shackles said no lift but I got the inch. Everything is tight and in good shape tie rods and ball joints.
There's your problem. Your drag link angle is too severe and you need to possibly flip your tie rod to correct the angle. It's obvious that the current steering setup would cause bump steer.
as long as his suspension actually moves then possible bumpsteer yes but the issue is DW. many of us have had undesirable drag link angles and no DW.

yes but again there are far more jeeps that look like the OPs that dont have DW and dont have crossover steering. there was a time when there was no such thing as crossover on a dana 30. any crossover kit will not affect scrub radius and ackerman.
DW is usually a combination of things. put the caster back to normal and go from there. i fixed a plethora of stuff and each time it got better but didnt go away completely. the thing that finally fixed mine was proper toe-in.
-insert meaningless out-of-place political diatribe-
I just changed the ball joints a little over two years ago! I hope that's not it they where a pain in the *** to get out.
This is your answer. I'm willing to bet you didn't check the ball joints cause you did them 2 years ago. Life expectancy on a ball joints with large oversize tires is severely reduced. Add to that the fact that many replacements are crap. I would check these again. You added 3 degrees of castor and now you have dw. You just changed the load on the ball joi ts considerably.
