Noise Diagnosis?
I posted earlier about the drive train whirring sound in my 1988 5 spd
Civic. It could be anything from wheel bearings to outer to inner CV joint to the transmission. Any great ideas for diagnosing these things without just replacing parts willy nilly? That gets kind of expensive. I suspect the noise is either my tranny, an inside CV joint, or a wheel bearing - but it sounds too central to be a wheel bearing. Any ideas would be most appreciated!!

Inner CV joints vibrate the car when accelerating. I've never had one that made a noise when bad. Wheel bearings generally make more noise when you load one side of the car in a turn. They also change tone with vehicle speed. Trans noise is the probable culprit. If the noise is the same in all gears but increases with engine speed then you need to have a technician inspect. You may have a input bearing going bad. |

Re: Noise Diagnosis?
A couple of guys now have talked about this input shaft bearing being the
likely culprit. Would this still make a noise if the clutch was in and coasting? What if the car were in neutral with the clutch in and coasting? The noise is identical with the clutch in. Haven't tried neutral and the clutch in though. Also, I think there is a little vibration when I accelerate - pointing to the CV inside joint? Is there a good way to check this - I tried wiggling it, but no discernable looseness. Got my wife to drive and I got in the passenger side and stuck my head out the window. Definitely not the right wheel bearing.
