Hi guys,
hopefully I'm not doubleposting, but search is limited to 3+ characters so no simple ABS search.

While browsing on the internet I found an interesting article here.
http://4x4abc.com/4WD101/ABS_parttime.html

It says that ABS is not working properly during part time 4x4 mode. They argue that simple because axles are locked together there is no way for the release difference beween axles rotation (binding)
To some extent it makes sense, but in reality ABS wants to prevent wheels from locking - keep them rotating equally while you have huge wheel slip already. Or better said keep them in block/steer/block/steer... multitasking modes, because best brake results are with stopped wheel, best steering result are with rotating wheel. If I can assume any potential binding will be released 15-30x per second through the wheel with least traction. Moreover during normal driving situation or during avoiding maneuver you hardly turn steering wheel more than 180 degrees, what should not introduce extreme difference in distance travelled by front and rear axles.
Dodge NP143 transaxle service mauals declares ESP and TCS functions are kept during part time 4x4 mode. Nothing about ABS. Owners manual has no warning about ABS issues in 4x4 mode.

Thoughts? Experience?
