Just recently my mom'* car started making a whirring noise on the driver'* side. I didn't extensively test when it does it, but just drove it so I knew how to describe it on here. When I let off the gas at about 25-30, there was a whirring noise that might be a bad CV joint or bearing or something. I shifted it into neutral while rolling along at 25 mph, and it still made the noise. The pitch of it seems to directly relate to wheel speed. Any suggestions as to what should be replaced? Tranny fluid smells and looks fine, thank god.
Also, it idled like hell, and I think it needs new plugs. I asked my dad, he said he hasn't ever replaced them, and he bought the car a little over two years ago. Which plugs and gap would be best for 100% stock? Can coppers be run? Those would be VERY preferable to the iridium that are recommended if it'* okay.
Edit: I read in another thread about a similar problem and it was suggested that it could be a hub bearing. If this is the problem, is it safe to drive with a bad hub bearing?
