Yes well sort of....

With TOD disconect switch, I am in 2WD mode....I can spin the rear tires endlessly, at will, W/O the front getting any REAL torque....the front is VERY disconnected in this mode....

ON the Dyno, folks HAVE had issues with the front wanting to pull a little bit, BUT this is with the front tires sitting still and the rears spinning at 70+MPH!!!
Difficult to repeat in real world driving....

With the TOD 4HI modifacation, you will have 50/50 torque split, (with no delayed grabbing) and this is a one wire mod!!!!

Normal TOD....we all know how that performs....
4Lo- 50/50 LOCKED....TOD is off...

There were some folks, a while back, that were working on a Pulse Width Modulation controller that would have SUPPOSEDLY allowed variable torque....0-50% to front axle....But that plan was scrapped a while ago???....

Nowdays, after tearing into a TOD unit myself, I can indeed see how simple it is to design a modifacation that will allow a steady 30/70% torque split as well, and possibly a few other pre-determined ratios....20/80% ect.....

I may even modify my current TOD unit, so as to remove the shift fork that locks the 4x4 in low range....In other words, I want to experament with LO-Range TOD....I feel that that the clutched design can and will save my CVs!!!! as the multi-clutch plates would absorb much driveline shock!
