Transfer Case Question

[redbird]

Maybe a dumb question
If I jack up both rear wheels, and leave transfer case in 4 wheel high(not locked) Will the front axle pull vehicle or will rear tires simply spin?

[tomp]

Front will pull

[redbird]

Both rear tires spin but vehicle will not move unless I lock the transfer case
so I guess there is a problem inside transfer case? Thanks

in 4 hi unlocked you should be getting 60% power to the rear and 40% to the front . t-case might be fine try getting all four wheels off the ground or find some sand and try getting half stuck and see if front tires will spin too . also try 4 hi-locked , that splits the power 50-50 front and rear , might be that your getting power to the rear before the front because more power is delivered to the rear axle in hi-unlock . good luck

I have done this in the 2 and it pulls. I would think the 3 would do the same thing even 4-Hi unlocked

I don't understand why?

maybe your doing something wrong. btw why and how are you testing this out?

Vehicle locked up at highway speed, slid front tires down to about 15 mph
at that point tires unlocked. It was probably brakes applied via the Stabiltrak
however I am trying to check everything.

One more thing. If I block front tires against something solid and force the rear to spin, I hear a clicking noise from lower part of dash around the steering column and the traction light flashes. The same sound occured when I had the brakes lockup and slide. Any help is appreciated

Sounds like the TCS/Stabilitrak issues others have been having. Caused by bad sensor(s). Get it in to the dealer.
