I put a lock-rite in the front and ended up doing a warn hub conversion cause I couldn't steer. It's a pain in the winter cause as soon as you lock the hubs the jeep doesn't like to turn any more, it just goes straight. So now i keep the hubs unlocked on icy highways so I can control where I'm going. I'll lock the hubs if I'm going to keep it under 60, but no faster.
