Hey guys, my car was making this whining noise last night and it's coming from the engine/front end of the car. The noise increases during acceleration and is present during idling and it seemed to be affecting my acceleration (seemed harder to get to a higher RPM) My car is automatic. I started up my car this afternoon and the noise seem to went away but I haven't taken it out for a drive yet since I'm a bit worried. Taking my car to the shop on Wednesday to get my front bearings replaced and hopefully they can diagnose this problem too.
Here are two sound clips I uploaded:
Any help is appreciated

Thanks!
