What should the pinion angle be on a 4 in lift wj be? I have death wobble pretty bad took it into 4 wheel parts they said my caster is bad a drag link end is bad but i just replaced it not even a month ago it went bad from a 600 mile trip i just took thank god its lifetime warranty lol

 

Caster takes preference over pinion angle,alignment should be at stock specs even though it's lifted,do you have adjustables or t-case drop??

Caster is usually more-so the cause of driveline vibrations...tons of causes for DW obviously,whats your setup and when are you getting the DW?

 

I have the rough country x series 4 in adj trac bar. Its the typical 40-50 mph bumps. Im running stock tires. No drop pitman arm. My lca are 16'' hole to hole. I re checked this afternoon and they are. Im running out of ideas
