I don't have a manual steering rack. But I do have a locker in the front of my rig with one piece chromo axles no CAD or posi-lock BS. Even in 4wd it's not that bad. I can't feel it hardly at all on the road and on the trail it's a little harder to turn and I usually have to do 3 point turns on tight switchbacks. Hell, I was at gulchfest for 3 days and never took my jeep out of 4wd the entire time I was there. And you would be amazed at how much easier everything is with a locker, It's night and day.
