More money with same results.

I've recently replaced my 3" pro comp lift with a King coil over kit on my 2015 DCSB TRD OR (2500 miles) because I wasn't happy with the way the old lift road. The ride quality on and off road improved drastically with the Kings but I still had some steering bump. So I ordering and installing a set Icon uniball UCA's in hopes it would take care of my alignment issues. Had it aligned to +/- 0* camber and toe and 2.5* caster.

From all the info I've gathered from reading through TONS of threads here on TW I This should've taken care of the problem but it hasn't. Still have the same steering bump when I go over the smallest of pot holes or drive over the reflectors while changing lanes.
How the hell do I get rid of this annoying ass steering bump? Don't know what else to do

 

Tire plies? Tire psi? Just wondering

 

Toyo AT running at 38 in front and 40 in rear

 

I would run something lower like 33 psi all around...on 35s I run 30

 

I'm running 285/70 17's. I'll drop the air down tomorrow and see how it feels.

 

on a side note, usually more air up front and less in back is better..... Rear isn't supporting an engine, battery, or trans..... I usually run 38 front, 36 rear on 6ply tires fwiw
