I think my turbo is rattling/making noise (sounds like a bad wheel bearing under the hood from inside the cab). Where do I get a re-build kit from? Do I need a new wheel too?
Take the turbo intake hose off and spin the turbo by hand, inspect the wheel to see if it has contacted the housing. If it has then yes, you'll need a wheel also.
I got my turbo rebuild parts from a local turbo shop, here is the part numbers for the kit.
