shreiking turbo
I've noticed over the past couple of months that my turbo occasionally makes a pretty loud shrieking sound on spooldown. Sounds like metal to metal shrieking like a bearing going out or something. The turbo seems to spool just fine and I don't detect much shaft play (there is a tiny amount, not sure how normal that is because this is baby's first turbo). I assume this isn't normal, but i'm curious as to what i can do about it? Does a rebuild usually replace all the bearings?

Yup, a rebuild kit will replace everything except the housings, CHRA, shaft, and blades... but with only a little shaft play and (I assume not smoking), you might want to look at something else. A turbo that needs a rebuild should always smoke at least a little.
You're 100% positive it's the turbo?

Yeah, no smoke at all and no oil in my IC pipes. I can't think of anything else on the car that would make that noise at that instant. I'll see if i can catch a video of it. i think my phone captures small videos.

there's no percussive sound to it at all though. it's more like dragging your fingernails down a chalkboard.
the turbo is probably due for a rebuild anyway with the miles that are on it. Where would i look for a rebuild kit for a stock Greddy kit turbo?
