Conducks Posted March 9, 2016 Share Posted March 9, 2016 Hi all, couple days ago my Legacy GT (5th Gen) started making a whining/sucking/grinding noise when on boost/WOT. Transmission still changes gears fine, almost smoother than before but it makes a strange noise. Torque is currently at 346ft-lb and power is at 290hp. It started doing it out of the blue and the only issue I've noticed is the sound. Fluid is normal colour and doesn't appear to have any debris in it and car has only travelled about 40,000 miles. Anyone got an idea on what it could be? I know America doesn't get the 5th Gen GT in auto but the trans must be similar to the last generation. Help?

FJuan Posted March 10, 2016 Share Posted March 10, 2016 I would start by pulling the Downpipe off first and inspect the play on the turbo shaft. Start by trying to move it up/down and in/out. If you have any play in the shaft then your turbo is about to go. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
Conducks Posted March 10, 2016 Author Share Posted March 10, 2016 I'm on 17PSi up from 13 stock so it's a possibility Link to comment Share on other sites More sharing options...

FJuan Posted March 10, 2016 Share Posted March 10, 2016 Based on your original post I would check the turbo out first, then work backwards. After that, check your wheel bearings. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
Conducks Posted March 10, 2016 Author Share Posted March 10, 2016 Took the intake off of the turbo and it feels fine to spin and doesn't wriggle at all Link to comment Share on other sites More sharing options...
Conducks Posted March 15, 2016 Author Share Posted March 15, 2016 Was a mere boost leak, thanks all Link to comment Share on other sites More sharing options...
