bump steer ?'s

[CHEVYJEFF]

Looking for ideas for curing my bump steer issue. after doing my 4" tci lift and adding my 35" bfg all terrains and steel wheels, I notice I have a pretty good case of the bump steer. When the truck hits a bump going while going straight the wheels seem to move the steering wheel really hard. The truck will go straight when hitting bumps but the steering wheel jerks left and right. Everything is new on the front axil and suspension. I installed a dual stabilizer and it helped but it seems to be doing it worse again. I was thinking about doing two things to help the bump steer. One is adding a drop pitman arm to go along with the raised steering arm already on the truck, the second is to install another shock on each side on front as it came from factory (quad shock) (only used one shock per side front when I did the lift) Only other thing I can think is the steering box is tired but there isnt much slop in it either.
