Fluid level is ok. Yup, I don't drive it on dry pavement. But people must think I'm nuts because I drive in the snow covered edge of the road instead of the dry track marks when its suck in 4wd.
I've tried all methods of shifting it. My driveway is shaded so always stays snow covered. I try backing up, then rolling forward as you suggested, rolling forward and turning left or right, etc. Nothing.
But since I'm in 4HI, the does the transfer case even need to shift to go to 2HI. The front drive axle always is engaged, correct? Then it's just a matter of the front axle being engaged or disengaged.
Is it the transfer case encoder motor that controls the vacuum to the front axle?
Thanks.
