2003 4.4 no awd

What do you mean if? The front driveshaft turns. I’ll just post a link to a video

Is this with all 4 wheels off the ground or driving it with the wheels on the ground?

The AWD system does not work like a 4x4 system with a locking differential...nor does it work like the facelift e53 X5 and all other "X" BMWs that have xDrive:

Minor issue here. Don't want to derail the thread. But I noticed some discrepancies here on the torque split numbers. I had always thought it was 68-32. Then I noticed the first figure in Qsilver7's post said 62-38. So I did a quick google and found that 62-38 had twice as many hits as 68-32. Then I checked my 2001 BMW owner's manual and it says 62-38.

So I figured it was 62-38 and I had just always been wrong (not the first time).

Then I skimmed down to Qsilver7's second figure and it says (in a BMW-looking doc) 68-32.

What?

If anyone has a dimensioned diagram of the NV125 gears the truth should be readable from the ratio of the inner and outer effective diameters of the planetary gears.

Doesn't really matter much, but I'd like to know.

Good catch...the same mental miscalculation is probably going on with the majority of people trying to remember the ratio. The 60/40 ratio is easy to remember for xDrive...but then the early planetary gear AWD (DDSC-X) with its slightly different ratio...most are probably remembering that its some type of 60+/30+ ratio and the 2nd integer is getting conflated.

I never noticed it until you brought it up...but I do remember past times when typing the ratio in a reply...that I've actually twisted the numbers around...then when proof reading what I typed...I'd see the 68/32 then pause because when I'd think about the number...I would change it if I concentrated on the 68 being too close to 70 and the 32 being too close to 30 (making the ratio more like 70/30 if rounded).

Again...good catch
