I have not thrown any money at my stock steering yet bc most people say it's more than likely coming from caster, ball joints, and axles not centered under the jeep. I have all new control arms, springs, shocks, trac bars, bump stops, ball joints, c gussets, and sleeves coming in the mail right now(not bc of shimmy). I hope once I install my new parts the shimmy will be gone? If not I'll start to address the stock steering. From what I've read on most forums it's not the stock steering causing the problems with bigger tires, but a lack in adjustments of the right parts. I've been told my shimmy is from running a 3" lift with no adj arms or TB's, and the stock BJ's wearing so fast with a bigger heavier tire. We'll see i guess?

BFG KM2's balanced by a local shop who have done several sets of tall heavy tires for me. I am going to get them rebalenced if I continue to have the issue just to make sure that's not the problem. If so then great if not I'll start looking at the stock steering.
