4 Wheel Drive Problem

[saif najd]

This makes it sound like and electronic lock out of some sorts. Maybe as not to overstress the tranny. Only one rear gear ratio in the tranny so to play it safe put the tcase in low. There are no sprags in the tcase or front axles that will do this. I have eliminated the speed sensors and the shift motor(actually still thinking this part out some more) and clutch pack and the TCCM has and does communicate with the pcm over the serial bus. Will keep looking into it.

In my case it is something new! It didn't happen before when I engage the 4wd hi I use to drive smoth I mean I can use it on road and I can take easy turns and U turns now if I am turning (on road) it jams!

Really strange for me, is it normal or it is something wrong I checked the oil level was fine

Were you in a force 4wd or auto4wd mode when each of the events occurred?
