Rear end feels like it's grabbing or binding under load HELP!

I just think the system that disconnects the front isn't working. The motor famously has a plastic gear that strips and the TC will no longer provide that function.. were it me, I would take that motor assembly off and see if it's broken or otherwise stuck in the front engaged position, then try to manually select disengaged, either by applying voltage or just turning the gear by hand that the motor does.

I'm somewhat good now..lol rwd x5 is now running and driving finally.. I'm going to be taking my gt1 scanner to it though the system though to see how I can better manage the system though.. I want it to try to rely less on trying to send power forward as the driving sensation as a one wheel drive isn't favorable..lol. because of the limited slip diffs we have, once you break your only working wheel free.. it automatically tries to make a front wheel compensate and it will fall on its face. (Plus steering with the speed sensitive rack is beyond weird because you no longer have the fronts to guide you into a turn). BUT, on dry normal driving.. it's way better on fuel! Once I recode the control unit and ecu to better manage the setup, I will let you guys know and offer the software to whomever wishes. (I own a mobile dyno service and that's what I do..lol). So this will be a neat experiment until I decide to properly dig out my front diff and transfer case in spring and do a system overhaul.
I just want to say thanks again for everyone's input and help to track down a temporary solution. Happy holidays all and a merry Christmas, happy new year and all that good stuff ��

How'd you get front disconnected? Physical removed the front drive shaft or got the gear to do its job.

I will be very interested in seeing what you find.

X5 is scary to drive on snow with no DSC I can't even imagine without front drive!
