Slow speed steering wiggle

Hello everyone, been searching for days for an answer to my minor but annoying slow speed wobble. I have a 99 xj with a three inch lift, coil spacers front and blocks and shackles rear, there is a slight wobble in the steering wheel at slow speed when turning left or right under ten m.p.h. oh I also have a set of general grabber at2s 30-9.50 and a transfer case drop kit and new steering stabilizer shock, it seem's this is a recent developemant since the lift has settled in, otherwise everything's golden with the cherokee and ready for the pipeline....

search "death wobble" you will get similar results

things to check in order of importance

track bar
axle shaft u joints
tires balanced?
tie rod ends
ball joint
and on and on

I've gone over everything in the front end except check tire pressure which I just did, guess what, problem solved :confused1 Dah. By the way left front was'nt seriously low but was down on pressure....
