I have a 07 5.9 2500 .I have had no problems whatsoever out of my truck until this holiday doing alot of traveling noticed my a.c wasn't cooling fixed that issue low freon and then all of a sudden start hearing a roaring/ gurgling noise think it is coming from around the turbo anyone have this kind of issue before any advice would help not really wanting to replace turbo hopefully something minor

 

Turbo bearings going bad? Pop the inlet off the turbo and see how much movement is in the shaft.

 

If there is a bunch of play what would you recommend rebuild or replace and what to replace with I have the stock turbo now no mods really just bolt ons and programmer? If rebuild what kit to use?
