So i was leaving work the other day and there was about 3-4" of snow and ice on the ground, i left in 2wd but had to go to 4wd to get up the hill and WOW, all i heard was a gosh awful CLUNK SNAP POP when i let the clutch out in 4HI.. Goin on a straight road with little pressure on the go pedal there is no noise but any increase in torque and CLUNK SNAP POP is all i hear.. It sounds like something is literally gonna break and get slung into the next county.. The sound makes me sick to my stomach! I've searched threads an some same u joints and/or the drive chain is stretched.. Any additional educated info would be nice so i know what to expect before i go to the dealership..

I would check U-joints and Axle joints 1st:thumbsup: A joint that bad should shake pretty easy by just grabbing the front driveshaft. If your axle joint was that bad, I would think you would be having an issues in 2wd. Still worth taking a closer look at. Past that, I'm sure someone else will chime in.

check you frontend for fluid pull cover to see if theres any metal in it. also check the fluid in your transfer case, and for any metal.

I don't think you should use the clutch when engaging 4 wheel drive.

DEFINATELY STAY OFF THE THROTTLE UNTIL
TRANSFER CASE IS ENGAGED if you are spinning on ice and snow and then hit a bare patch while engaging you
will tear something up, no doubt about it.

That sounds like what happened to you,simply turn the knob and wait a bit .It tells you when you are in gear.

AGAIN....PLEASE STAY OFF THE THROTTLE WHEN SELECTING 4WHEEL DRIVE.:doh:

Thanks, in 2wd it's fine no noise at all just in 4hi or 4lo...
sounds bad. bad axle u joints may not make a sound until you put it into 4wd..i just replaced both in the past 4 months. the left one wound up clicking after a while when turning 2wd, but for the most part i couldn't hear either were bad until it was in 4wd... then it made a racket. check them first, then the driveshaft joints, then onto the transfer case.

Idk but it just started it all at once! It sounds so bad it literally scares me but like i said it's fine in 2wd.. Truck has 72k and everyone in past threads says that the front driveshaft u joints go bad around 70-80k plus my rear driveshaft u joints are bad i just aint had a chance to get them replaced.. Guess my Dodge place will be drooling when i tell em i need all this fixed.

Pull the front diff cover and check that out. I would also check the cv joint in the front drive shaft it could be worn.

My guess is that it's the transfer case chain. Everything turns all the time anyway. The only thing you do when going to four wheel drive is engage the tranfer case chain. If it were anything up front it would make the noise in two wheel drive as well.

If you have a buddy with a porta power then you can split it yourself. I bought all the bearings, chain and seals for around 300 bucks from the dealership.

I understand that. Need a warranty then. I'd say dealer is your best bet. My guess it will be parts plus labor. Labor is probably around 70 bucks an hour. My guess is that it will be billed in 3-5 hours.

I would check the front drive shaft universal joints. Had similar issues and that’s what it turned out to be. It was strange because you would think it have made the noise all the time considering the front end is always engaged, but it only did it in four wheel drive. Hope it's nothing to serious...
