SOURCE: Chevy Transfer Case
The most common thing to go wrong with chevy transfercase is the rear tailshaft has a snap ring that breakes. Just remove the bolts holding it on and inspect the shaft and see if the snap ring is broken.Then just replace it with a new on from the dealer.

It does not seem that sufficient diagnosis was done. No, you cant give a specific diagnosis like that without tearing unit down. It's likely that they told you the most common failure and left it at that. Likely there is a problem with your unit...I think this becomes more of a trust issue than a mechanical one. A second opinion from an independent reputable shop may help but either way, you need to have it fixed. In not using it much, it makes me wonder how it got worn.

I have seen this problem on many gm trucks including my own 1999 chevy tahoe with the NP246 transfer case model the rear out put bearing has a plastic cage the falls apart and or the clip holding it in place shatters causing this noise you can inspect this by removing the rear drive shaft and with a flash light look into the transfer case tail shaft to see if every thing is intact. also this type of transfer Case is known for the drive chain to stretch and hit the inside of the case housing start by checking the bearing first.

One thing to check, which is often the culprit in these situations is the U-joints. With the truck off, crawl under the vehicle and grab hold of the shaft leading into as well as the shaft going out of your transfer case, If htere is a lot of "slop in it, chance are it is in need of repair. Also I would check the oil level in the transfer case, in an attempt not to challenge you intelligence, there should be a plug located in the lower part about 2 inches from the bottom or so. it usually has a square hole that a 1/2" ratchet fits into. Pull the plug, and stick your pinky into the hole, you should be able to feel the lubricant just below the hole, if not it is in dire need of a filling. also check for metallic remnants in the fluid. this is a sign that things are not as they should be. In that case contact a repairman for a more thorough look.
