I have a liberty KK 2012 and I was wondering if that breaking system jeep uses in place of putting in lockers works on both axles at the same time? What I'm trying to say is if 3 wheels where in the air would the 4th one still try and pull you out? I hope this question makes sense. I ask this because I only here that grinding sound from the rear end never from the front. I thought I'd ask here instead of jacking up 3 wheels to see if she still tries to pull on the only wheel left on the ground. Anyone know? lockers would work if something didn't break first Thanks.
