Hi: new guy here, I have a 2006 Corolla CE(SE) 5speed with 4500kms, just recently I have been getting an annoying/worrisome noise, at first it occured at highway speeds (100-120km) but is getting noticable at lower speeds.......when I let off the throttle I hear and somewhat feel a "bearing type" noise at my feet, drivers side firewall as soon as I apply some throttle the noise/feeling goes away...its been to the dealer once already and they performed a TSB repair 4501, but that addressed noise when accelerating, which isn`t the case with my car.........anybody got any ideas?
