Leeb Posted July 2, 2023 Share Posted July 2, 2023 30 dnt, was driving fine after repairs from a big crash. All of a sudden all 4 wheels lock up. Was as though the brakes had come on but they hadn't. The drive shafts from the center diff wouldn't move at all. I figured the center diff must have broke but i've taken it off and it looks fine. Without the diff in everything moves freely, I took the diff off and it also turns ok. Thought i'd take the center diff off and it would be locked up but it wasn't. Got the diff draining i'll take the opportunity to change the oil. Maybe i'm missing something obvious ? I can't think what. Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted July 3, 2023 Share Posted July 3, 2023 Drive shaft knocked out of position jamming the diff drive cup. No way to tell now you pulled it all apart.... but if all your diffs are working correctly, all the diff bearings are good, and the drive cups and driveshafts are not bent or damaged...,. put it back together step by step, and check each assembly. It may just be fine Quote Link to comment Share on other sites More sharing options...
wolfie1 Posted July 3, 2023 Share Posted July 3, 2023 Im going to hazard a guess at a broken tooth on 1 of the gears Quote Link to comment Share on other sites More sharing options...
Leeb Posted August 12, 2023 Author Share Posted August 12, 2023 Worked perfect after the strip down and draining the center diff, no foeign objects getting in the way of the drive train. Genuinely at a loss what caused the lock up Quote Link to comment Share on other sites More sharing options...
