Transfer case not working

I check the thing you sent but the transfer case was low in oil so I put about 2 quart in so when I put into 4th low and start the engine and come of the clutch the front wheels will not turn but I can keep on moving the four wheel drive shift lever back and forward it make a noise and hard to shift and when it do catch the front wheels turn for about 2 second and stop. But the lever is hard to shift what could be that cause? The back wheel don't turn when put into 4th Hi because a gear in the rear end is worn out.

I didn't see anything wrong with the shift linkage and I didn't see any vaccum hose around the tcase. Can I bypass the front wheel pull and Just use the rear wheel pull? But I need to replace the whole rear end because the one in the truck is bad. When I do replace the whole rear end can I Just use the rear wheel pull?

the 4 wheel drive don't work.
I put it in 4 wheel drive and the light lights up on the dash, the drive shaft turns, the actuator on the radiator pumps air to the unit but the axles don't engage. What is inside the unit that makes the axles engage? What can I do to fix it?
Thanks

The four wheel drive does not work in my 1993 chevy truck. My husband put a actuator in it and the fluid is good but still does not work. My question to you is what else could it be?

My 4wd does not engage. The shifter is working properly and the front driveshaft turns when moving forward if the transfer case is in 4w hi or low however the acuator does not engage the front axles. I checked for power at the actuator wiring harness and there is no power on either terminal in either 4w hi or 4w low. There is also no power in 2w hi. I did not notice a fuse in the fuse panel for the 4wd circuit so I am stumped as to how to figure out this issue. What should I check next?

There is a fuse in the panel.25 amp about the middle of the panle

The fuse is good but I did not think to check and see if power is getting to the fuse. I will try that first. Any other suggestions providing power is getting to the fuse? Are there any switches in the system that would prevent power flow to the actuator? Thanks to all who can help with this matter.
