Death wobble
 

Lifted 2014 Mega Cab Dually 4x4. 37x12.50x22. At low speeds and I hit a bump, I get the death wobble. I have raised the truck and checked for play on both front tires, and I cant find any. I know in my 04.5 3500 4x4 I had to replace the steering bar and ended up putting on the aftermarket brace that hooks to the pitman arm. Is anyone else having this issue? Thanks for the help.
