Sup guys? New member here, i drive a 89 Yj with a 2.5 with a d35 stuffed with 4.88s with an Aussie Locker. I was driving to work the other day and it locked up on me......i was doing about 25mph and my Jeep started bogging down like i was riding the brakes. Then pop my back tires lock up. What could it be? I disconnected the driveshaft, still nothing. Opened the rear diff and couldnt see anything wrong. no netal shavings in the diff, jack it up on jackstands and i can turn on tire but the other wont. Completely locked up. HELP!!!
