1998 Corolla - Odd Sounds

Hi all!

I have a '98 5-Speed Corolla. If I rev the engine when the car is in neutral and warming up I hear an odd grinding noise when I let off the gas and the engine goes down to idle. The noise does not occur if I put my clutch in. Is this something to worry about?

Also, I’m wondering what CV joints sound like when they’re failing.


Check the transmission oil level.
