Shimmy/steering issue

[Scott in NM]

Ye olde jeep was beginning to shimmy on its own accord doing 40-45 mph. Disassembled right front axle and readjusted the flange caps per the manual. Reassembed same. Shimmy now gone, but can only turn left two spokes of the steering wheel vs four for a right turn. Didn't do nuthin' else, I promise! So what did I do wrong?

Also, I was originally planning on disassembling both sides of front axle, but shimmy is now gone and I sure don't want to fix somthing that isn't broken. Should I just hold off tearing apart the front drivers side axle to see if the shimmy returns, or assume that the problem was on the passenger side? Anyone have a recommendation to pull the left side apart just because I have nothing better to do for three hours? Any and all inputs greatly appreciated, thanks!
