mikec1 Posted December 6, 2021 Share Posted December 6, 2021 Have a strange noise coming from my front right near the turbo, only notice it in first gear, off the gas and cruising to a stop sign. Sounds like gravel in the turbo, no obvious heat shield rattle or anything. Any thoughts? Link to comment Share on other sites More sharing options...
whitexc Posted December 6, 2021 Share Posted December 6, 2021 (edited) How is the car running? Any lights? Guessing this is your 2008 so no cat in the UP. Had a look at the turbo, check for shaft play recently? Front axle?

shralp Posted December 6, 2021 Share Posted December 6, 2021 If it sounds like rocks inside of a can then your turbo may be starting to go. Once you get play in the shaft the compressor wheel strikes the housing and you chip on of the blades which throws the whole thing out of balance. Depending on how bad/where the imbalance is on the compressor wheel it can be rpm dependent. Would definitely have the turbo checked asap Link to comment Share on other sites More sharing options...

Would definitely have the turbo checked asap Checked for shaft play to which I found none, but will pull the entire turbo tomorrow or later this week. Had an OBXT blow its turbo and didn't really sound the same, but it was a 5EAT so chances are high the turbo is going Link to comment Share on other sites More sharing options...

Yes, 2008 is correct, running all aftermarket exhaust anyways. No visible shaft play, axles are tight. Will pull the turbo soon to check for sure.

Pleides Posted December 6, 2021 Share Posted December 6, 2021 Can you record the sound? My 5-speed manual is the absolute most noisy and obnoxious transmission I've ever heard and it has no major issues. Wondering if this is a new noise or a new car to you.

NORULZleggy Posted December 8, 2021 Share Posted December 8, 2021 Could it be bearing in the trans? I had the marbles sound and it was in the trans. Link to comment Share on other sites More sharing options...
