I'd say yes... even in 2wd. Even when AWD is not engaged.. the front hubs are still connected > still turning the front axles > still turning the front pinion > still turning the front driveshaft > still turning the front half of the transfer case. Meanwhile the back half of the transfer case is also still turning from engine output. Both sides in the transfer case are simply are not physically connected.. but everything everywhere is still all turning! The drag remains the same.

The only advantage to uncoupling the AWD would be to reduce wear in the transfer case due to subtle variations between front and rear..particularly in turning.

I can't speak regarding the S10 setup.

Are we talking the hubs are engaged full time, as in the axles are always spinning even in 2wd?


Yes, the hubs are always engaged in the AWD Astro.... The diff is an open diff, however, so the hubs are not locked to each other as such...

The S-10 setup as mentioned above has a disconnect in the RH axle which disengages the RH hub, allowing the diff to stop spinning

Thanks for the clarification.

Dang, got me all excited thinking the diff was locked.
