Pull the fill plug on the t-case, once you have it out, pull the drain plug, capture the fluid, and see if there is anything you'd rather not see in it.

 

ok will do. Im gonna do a tranny service change fluid and filter any special fluid i should use? also is it same kind of fluid for the t-case or do you fill that up seperately?

 

I'm thinking maybe you have a vacuum problem. And what you are hearing is the front axle. http://www.dodgeram.org/tech/repair/..._engagment.htm

 

Ya that happened to me but it was a consistent grinding noise, if you look at the vacuum lines by the front of the skid plate (mine where red and black) they go to a metal tube (near the y pipe) where the exhaust burnt a hole in it. I replaced it and the noise went away.

 

*if that's your problem, i didn't read the whole post.

 

would that cause the tranny to not go into gear?

 

would the vacuum maybe cause the t-case to maybe shift into neutral? where i wasnt getting reverse or forward gears? Kinda makes sense. Just wierd that it stopped and now works fine now.

 

No, vacuum won't do squat to the T-case. Shifter on the t-case just pushes around a vacuum switch. That's it.

 

Have you tried shifting the t-case into the different gears???

 

Just throwing this outa the blue, but maybe the tcase chain is heavily stretched and its skipping teeth ? I know on my Jeep when you go from 4Fulltime to 4low it will grind REALLY bad if you dont YANK! the lever back really fast and instead pull it really slow.. (Your suppose to yank it fast fyi)
