so i was checking my four wheel drive today and i started the jeep, and jacked one front wheel off the ground and i checked how much i could spin it and i got 25-30 degrees, i figured that was too much, and that i shouldn't really have any play. but i can do 4 wheel burn outs on dirt roads and i can feel it locked up when i turn. i just want to figure out if its too much. thanks
With it running & the tcase in 4wd (assuming the tranny was in neutral) there NEEDS to be movement of the front axle components before the vacuum disconnect collar engages UNLESS the remote possibility happens and the passenger side two piece inner axle shaft splines are lined up.
In other words - most of the time the differentials & axle shafts will need to spin some before the collar finds the sweet spot & allows for the axle shafts to lock together.
