Turbo Bolwn or blowing up? 2003 6.0

Ok, A few weeks ago I noticed it was whistling real loud at idle. It would go away once i reved the engine. Then just a few days a go it started to sound like a vacuum cleaner. It made this strange noise that sounded like "whoooooooo" and it just went up with the revs. Just today the vacuum cleaner noise comes from the "whooo" to a squealing/screeching noise when you rev the engine. It does not happen all the time but is happening more frequently the longer i drive it. The vanes seem to be sweeping and it is putting out boost. My guess is it is a bearing failure. Can i just rebuild it myself? and does the shaft have to be rebalanced? Any help is appreciated. Thanks. Btw,I already parked the truck to avoid further damage.

I would imagine I'm not the only one with this problem being the 6.0 out sold Cummins and Duramax sales combined. Some one else had to cross the issue or rebuilt the turbo by themselves.

Please forgive me, I don't quite understand what your trying to ask or tell me. The truck will go though the "vane sweep" as it idles after the software update.

Mine seems to run fine, however Thursday morning after I shut it off I heard a squealing/whistle sound. Sounded like a bearing or something from the Turbo. The truck has never done this before. This started Thursday and it does it about 1 out of two times I turn the truck off.

I appreciate all the input. But however people telling me "I have the same problem" is not helping me at all. They sold over 100,000 6.0's so I would imagine I'm not the only one to have this issue. I'm not in anyway trying to be rude but I am trying to figure out the best route to fix the turbo in the most economical way possible with out just throwing parts at it hoping to fix it. I know replacing the whole turbo would fix it but IF I can just rebuild it it would save me a lot of money. I am very well mechanically inclined and ASE certified in 5 different areas. Also any info given to me will help all the people who have the same problem. Once again, I'm not trying to be rude but trying to just keep the forum full of good information.

To me that sounds like a bearing failure. the turbo will still spin for a bit after shutting the engine off. Most likely a bearing rebuild will fix that. Any metal in the intake, exhaust, or oil?

Climb under your truck and check your up-pipe and your y-pipe going to the turbo for leaks. You should see some soot around any area that is leaking.

I'll use the "I have the same problem" line because my passenger side up-pipe is cracked and it makes a high pitched squeal/whine at different times. I thought it was a turbo bearing at first because it has that kind of a sound to it!

check your shaft play, maybe the fins are starting to rub. And as for rebuilding these turbos. you can't. I have tried. i had one that spat out an exhaust seat though the turbo, we fixed the engine, when we took the turbo apart we found a couple of the fins on the turbine broke, and bits of metal indebted in the veins. trying to get parts for these is damn near impossible, so we just cleaned everything up and put it back on the truck as it was since the owner said it was okay and didn't have the money for a new one. truck is still running strong to this day and it has been over a year and a half now. anyway, i had to trace down the big clamp that holds the exhaust side of the turbo together. it kinda looks like a big down pipe or y pipe clamp. i think they call it a marmon clamp. but to get one of those i went to a company that all they do is rebuild turbos and they gave me a used one they had laying around and told me in order to get just that clamp, you have to get the entire half of that turbo with it. so they don't really just sell the parts and they are really precise. your best bet would be to get a rebuilt one for around 850 is what i have seen them priced at.
