This bw44-44 actually has the potential to be a really good transfer case.
I keep going back to that torsion spring as a source of trouble. If that spring had a significantly lower force/rate value and would allow the ball ramp to engage ANY time the rear driveshaft attempt to advance clock position beyond the front driveshaft, it might actually work well.
That spring seems, in the case of some trucks, to only allow ball ramp engagement when there's a significant force differential between the front and rear drive shafts.
In the case of a low friction surface, the rear drive system rotates against the torsion spring, and the torsion spring is strong enough to rotate the front drive system on the low friction surface, via the weak electromagnetic closing of the clutch, without allowing the ball ramp apply its own axial force through the clutch plates.
I'd love to try the system with new clutch plates and a torsion spring with about 10% the strength of the current spring.
