Ok this thing is getting to me. When I move the on dash switch to 4h sometimes it goes in 4wd and sometimes it dont. Also sometimes when its locked in it will disengage when you are moving and pops hard and loud. any suggestions on what it might be?????

It's more than likely the TCCM, or transfer case control module. I'd shop around and find a used unit. RockAuto and car-part.com are good sources to look for a TCCM in your area. Not everyone calls it that, it's just a generalized term that MOST people should know. A bad TCCM can lead to no engagement and disengagement of the transfer case. I'm sure the transfer case itself is OK, but I wouldn't use it unless absolutely necessary until you get it fixed, or in this case, replaced. Stay away from dealers as they'll charge $500+ for a new TCCM. A used one should run you around $100 or so, and it can last just as long, if not longer than a new unit. Shop around.
