96bulldogpower Posted 7 hours ago Share Posted 7 hours ago Hey guys I have a CHN with Mack rears that snapped a thru shaft last week on the front/rear. I had spare parts at the shop so I waited till I had time to pull them and just got around to installing today. It seemed pretty simple, the shaft snapped and it pushed the half with the yoke straight out of the aluminum seal flange. After replacing the broken parts I turned the output yoke by hand and it spun the front yoke as expected. Unfortunately every so often if I’d spin it faster, it would feel as if something inside would slip as if a spline was stripped or something. I put everything back together and with the power divider unlocked, the truck would spin the rear tires even with the brakes at near full pressure, so it leads me to believe it’s okay? Am I missing something? Would the auto power divider make it behave that way when spinning it by hand?
