I have a 99 civic ex with around 115k on it. I am noticing that there is a whining noise present when driving at low speeds. its seems almost as it something is grinding slightly. Its a sound that is continuos and is noticable only when the car is in gear. Any idea what that could be, just trying to get a general idea, before tearing everything down.

peace

Or one of the tons of other tranny grinding threads. Those will help you diagnose what is actually bad.

My input shaft bearing went bad right around 115k.

 

probably a bad ISB (input shaft bearing)....does it make noise at idle? if so, put the clutch in and if the noise goes away it is def. your ISB. ^the link above has some good info on how to change/inspect the ISB. I think it is somewhat of a common problem, that is why I am guessing that is what you are hearing in your tranny.

 

thanx for that link, it was pretty helpful. I guess i have some work lined up.

 

also thanks for the thread, it helped me out a bunch
