Bump Steer after axle swap.. Please help

Ok, first a little history..
A couple years ago I changed out my front springs because they were nearly resting on the bump stops, I replaced them with 4000lb "x"code+ springs.
I just lowered the axle, pulled the old springs out and put the new ones in, new bolts at the spring ends and u-bolts.. I didn't mess with the track bar or anything else i didn't need to move in order to do the spring swap.

The springs currently have ~40k miles on them and give me ~ 3" of lift over our other 99-03 superdutys..

This week I installed a D60 axle from an '03, new u-bolts, removed and reinstalled oem track bar, new tie rod ends, etc. just got an alignment today.

I have bump steer like crazy.. hit a small pot hole, bump, or somehow compress the suspension and the wheel makes almost a quarter turn.. It didn't do this at all before the axle swap.

Would an adjustable track bar solve my problem? Drop pitman arm?(supposingly only needed for 4"+ lifts)

All input is appreciated.
