My '03 TJ is making a whining noise. It only occurs when I'm in gear and coasting. The noise goes away when I accelerate, but as soon as I take my foot off the gas, it comes back. Also, when I reverse, there is a squeeking noise in tempo with the tire rotation. It goes away when I engage the clutch.
I'm not sure if the two noises are related. My coworker has told me that I could have chipped a tooth off of my flywheel or that it could be a loose belt or belt pulley.
Does anyone have any ideas what the problem(s) might be?
