Whirring in revolutions??
Hi everyone! So, I just recently bought an Evo 8, and I’m in love with it. Childhood dreams come true!
There are a few things going on, though. As of right now, it is making this pretty loud whirring noise around 45–50 mph. It is VERY loud at these speeds, with practically little to no noise below them, but it can faintly be heard above these speeds.
It kind of makes the noise in loops, if that makes sense? Something along the lines of a loud differential or possibly a wheel bearing? But the noise is more like a loud vmmmmm… silence… vmmmmm… silence… vmmmmm. That’s what I mean by the loops or revolutions.
It sounds like it’s coming from the driver-side rear. I’ve had the car in the air and touched a few things with a stethoscope: the center support bearing, differentials, wheel bearings, transmission, etc., but no luck with anything being particularly loud. Everything actually sounded pretty quiet.
I should mention that I had the car in the air in 4th gear doing 50 mph because that’s when the noise is most prominent. The only thing I noticed while I was under there was that the rear wheel was very, very bent back there. I’m not sure if that could have created something because the car is AWD?
Since then, I’ve moved that wheel to the front just to see if anything could change by a stroke of luck.
Any insight or suggestions would be greatly appreciated! I’m new to the Evo platform. Also, I can try to get a video of the noise from the car after work!
