Disconnecting TOD

[Scott Larson]

I think what has been forgotten here is that the TOD relies on several clutches that distribute the torque. Inasmuch as they are clutches, they tend to drag regardless of torque applied. That said, the drag will rotate the shaft even though they exert no actual useable force. My two cents, please remit change...

I checked my trip odometer the first time that I towed the VX 4 down with locking hubs & quick disconnect on rear driveshaft. Nothing registered on the ODO after a 400 mile drive.
Not 'Xakly the same situation but though I'd throw that out there.

My personal guess is that you are probably getting some small amount of viscous coupling through the transfer case, or a minimal amount of clutch drag ... or maybe a little of both.
So you may get a bit of rotation on the drive shaft but I doubt that any torque is being applied.

You could make a small 'flag' out of duct tape on your drive shaft. If power is being applied, it'll spin fast & the sound of the flag slapping the snot out of your floor board will let you know (without damaging anything). If it's just a small amount of rotation caused by viscous coupling or clutch drag, I doubt the shaft will be turning fast enough to make the noise.
