Vitara 2001 4x4 engaging problems

[bimin]

I need help please!!!
I got a 2001 vitara auto hubs. I shift in 4x4 the light goes on but the front wheels dont work. I checked my pump and it pumps ok. My front shaft blocks when I put it in 4x4, so my transfer case is ok.
My front axles right and left are locked.
I heard about someone who said he put 40 psi in differential to free jamed piston. Can I really do that with out breaking anything else?
What is the problem, anyone know?

Ok I made another test. I got it on a lift, I put 4x4 on, put it in second gear and nothing happens to me front shaft. I turn my front shaft with my hands and my front wheel respond. Its in the transfer case my problem I guess.
Anybody ever got that problem?

It's strictly a mechanical thing with regards to a manual transfer case. If it's not a problem with achieving FULL distance and engagement with the shift lever, then it would seem apparent that you have broken gearing or possibly pins, press fits or shaft keys (whichever secure the mechanicals internally), is my assumption.

Do you have high range and not low (or vice versa)?

Does placing the transfer case shift lever in NEUTRAL disengage the REAR axle?
(trying to establish if an internal selector lever problem here)

Did you notice any noises / problems leading to this current situation?

Any history of changing out the gear oil? (or NOT).

ok thanks...
It is indeed manual transmission. Low works but stays on 2x4. No appartent noise. Dont know about the oil changes done on it, has 100,000km.
So it would probably be in the tranfer case, I could get one used for 300.00 probably less complicated by replacing it.
Thanks......
