No 4x4 06 NBS
My 4x4 will not engage at the front differential. This is the push button 4wd with auto function. I can hear the t-case engage, and all the lights on the switch panel work correctly when changing between 4HI, 4LOW etc..
I raised the truck and ran in 4wd high and low, and it will turn the front wheels, but as soon there is a load applied (stopping the wheels with your feet), the power will then all be applied to rear wheels (front shaft stops turning).
Seems like something is slipping in the t-case... The fluid is fairly clean, and no metal. Has anyone dealt with this before? I searched TSB's and the forums, and nothing matches.
WHAT DO YA THINK???
