Loud cracking coming from tranfer case

[The Other Rob]

At times I was actually talking about both the front and the rear.. The rear failed once.. Repaired under warranty.. Haven't heard of many folks complaining about the rear compared to the front.. The pic you posted is what mine looked like the first time it failed.. Once again, fixed under warranty.. I've since found out it's really not that difficult of a repair.

I haven't had any issues with my transfer case.. No idea what the failure would sound like other than CLANK CLANK GRIIIIINNNNDDDD.. Clunk.. Check the rear of the front driveshaft though.. Grab it and shake it like a kid standing in front of the TV during the Saturday morning rasslin show.. Inspect the rubber gasket on the CV end of the shaft... Check the U-joint on the other end.. You may have to pull the drive shaft and "wobble" the CV around .. Feel for grinding and binding.. Do the same with the U-joint end.. Be careful not to let the caps fall off and bounce the needle bearings out..

Thanks for the info.... Yeah the sound coming from the transfer case is a cracking noise... Kinda like if you took a ball peen hammer to the side of it.... And it only does it when its in locked mode... I've been under it and shook, yanked, beat, pryed all of the driveshafts and the only thing I've noticed is some play in the front propeller shaft when I have the truck running and in locked mode with it off the ground.. I can turn the driveshaft about a quarter thhe way around... It seems like the locking mechinism might be failing? I've never seen an exploded view of it so I don't know the way it actually works... I don't know what I'm going to do at this point... Just hope it lasts through the winter I guess

Any update Midnight?

Still no go.. dealer keeps telling me the noise from the trans is normal and can't find anything wrong other that digging internally in the transfer case.... The shop I used to work at is going to take a look at it next week.. dump the fluids and see if and how much metal is in the fluids. Then ill have to go back and fight with the dealer since I've been fighting with them about this since its been under warranty... Now not... But they should have fixed this long ago...

I forget who had a similar issue to yours Midnight_H3. But they ended up finding out that their T-case chain had stretched and it was "smacking"/"slapping" against the inside of the t-case.

Hope you find out what it is and those GM 'tards fix it under warranty like they should have a while ago!

I so feel for you, relating with all the emotions that you are no doubt feeling.

Sounds like you are dealing with a 'No Problem' dealership as I did, when in fact my Hummer had extensive problems; however, none of the problems he was having was covered under the warranty.

You might want to check into the Lemon Law which protects consumers who have a warranty and the dealership is not honoring this warranty.

Currently, I am suing the dealership for the cost of my repairs and the emotional trauma endured through the nightmare, who sold me Kashmir under a different facet of the Lemon Law, which is called the USDP; Unfair and Deceptive Acts and Practices — Every state has an Unfair and Deceptive Acts and Practices (UDAP) law. These laws can often be used even if the used car is sold "as is," as long as the dealer is guilty of a verbal deception or a failure to disclose information about the vehicle.

Just some sound advise, if you plan on getting the law involved make sure you record everything, the dates and what was said. I am quite fortunate, while I did not record a lot, I did cry my blues through HXC-recording a lot-I have a date stamp and what was said in more ways than one.

The dealership now claims, I did nothing to let them know that Kashmir was having problems. I was a consumer that just walked away, destroyed my Hummer, then want them to pay the bill for the repair cost. The beauty of it all is, when Kashmir was in the shop, their shop for two day's a friend of mine, took me to pick him up. She heard them tell me 'No problem with your Hummer,' blowing their deception right out of the water, in addition, to all post I made through HXC.

(Sorry for hijaking this thread) Sending you positive vibes across the miles-I hope all works out well for you soon.
