you should be able to go into 4hi slowly moving or sittin still, only go to nuetral to get into 4lo. go to nuetral hit 4lo sittin still it should clunk, put it in drive see if its in low... yes the transfer case is in and out fine, now back to nuetral hit 4hi see if its engaged at the front, if not go back to 2hi and hit the front axle actuator then back to 4hi if it still doesn't work i'd replace the front actuator

Ok now things have change since last reply.

was driving around and then i heard sound like grinds under the middle of the truck.Stop put to neutral and push the 4wd button and it just ticking sound from some relay but push 2wd button and start driving and no sound then but after few miles it starts to sound like grinds again.

Is the transfercase broking down or what a heck is wrong

Bahahaaa you 2 are hilarious!

IIRC the transfercases are know to break. The actuators are common to go but if your hearing grinding then its probably the transfercase. There chain driven and alot of times the chain will break, get loose, or go bad. If its was just the actuators it wouldnt try to go in at all and there wouldnt be any grinding. My opinion!!
