Car Forum / Nissan / Nissan Cars / March 200696 Sentra noise
My 96 Sentra 1.6 with manual transmission makes a whirring/humming noise between around 20-50 mph. The noise is most prounounced when accelerating, though it can be heard faintly when coasting in certain speed ranges. It appears to be orignating in the front end from the half axles or transmission. This noise has been ongoing for almost a year and performance doesn't seem affected. I just need some direction on what could be causing this to prevent any serious problems down the road. Thanks for any input. I had a noise something like what you are describing, but on a different type of car. It ended up being the throw bearing for the clutch. On another car, I had a sort of humming noise in a particular range of speed. This one turned out to be a bad gear in the transmission. This car also had a manual transmission.

The radio's off, windows closed etc. Push and release the clutch pedal. Does that same noise come and go? If so, then it's the throwout bearing. Time and use have thrown it out of wack. Best thing is to leave it until the next clutch change, or if it gets severe, replace it AND the clutch since you need to do open heart surgery on the tranny just to get to the bearing, and you may as well replace the clutch as well.
