Question 4" RC lift + 2" shackle lift = B.S. steering ???

So i recently lifted my yj (4.0L / Ax15 w/sye kit) i got a 4" Rough Country lift & some 2" lift shackles. with a 4" drop pitman arm. it has no track bars on it, and @ first i was running it with no swaybar, i figured that was the reason for the steering being so sloppy.. so i put on some poly swaybar bushings & a 6" swaybar disconnect & reinstalled the swaybar.. Still the worst steering jeep i have ever drove in my life. What i mean is if im driving & i have my hand @ 12 o'clock on the wheel i can move the wheel 90 either way ( 9 o'clock position if turning left, and 3 o'clock position if turning right) before it starts to move the tire @ all.. i know its a lifted jeep and its not going to have the greatest steering response but is there something im completely overlooking

if it was me i would put the stock length shackles back on. you should be able to clear 33's with a 4 inch lift. it may or may not help but it definitely wouldnt hurt.

shackle lifts change your caster in the front and the pinion angles front and rear. is it a 2" shackle lift or a 2" longer shackle? if it is a 2" shackle lift that means it is 4" longer than stock.

its just 2" longer than the stock shackles were center to center. they are pretty big though. pinion angles seem good, no driveline vibrations @ all. just the crappy steering. i was going to make a high steer / crossover steering setup but i dont want to waste my time if its just going to be the same as it is now...

have you checked all your joints in the front end? have somebody hop in it and turn the wheel side to side while you watch the steering components. see if anything looks loose.

edit- have you had an alignment on it. if you dont have the proper toe in they have a dead spot. the pinion angles arent going to effect the steering but the caster will.

yea i checked with my friend turning the wheel i went over everything & i didnt see anything abnormal..

i havent had an alignment yet, but last time i took my tahoe to have it aligned @ belle tire i almost smashed the smart assed tech in the face when he told me that caster isnt an adjustable angle & that they couldnt adjust anything on my lifted vehicle other than toe..

you have to add wedges or cut your knuckles and spin them. there is adjustment for slop on your steering box also. is the pitman arm moving while the steering wheel is being turned within the dead spot?

if the pitman arm is moving while the steering is in your dead spot then it probably isnt the box. i would use an angle finder and check my caster. i would also check toe in.
