After installing a new clutch which included installing a new flywheel, a new pilot bearing and a new throwout bearing, I am getting a high pitch whining noise in 5th gear @ 2900-3500 RPMs. It also happens a little in 4th at higher RPMs, but it's in 5th gear where it's really noticable. It goes away immediately when I depress the clutch pedal. It's not the same noise that the old throwout bearing made which caused me to replace the clutch in the first place.
It's not crazy loud, but loud enough to be slightly annoying.I never heard the sound before I replaced the clutch. But then again, I had a bad rear wheel bearing that I replaced with the clutch that might have been drowning it out before. I was thinking it might be some sort of sympathetic vibration, but then I would expect the noise to happen at the same RPMs regardless of what gear I'm in, but it doesn't happen in 1st, 2nd or 3rd and barely in 4th. Car drives and shifts fine. (no better or worse than it has for the 7 years I've owned it) Thoughts? |

(IMG:style_emoticons/default/agree.gif) You described my symptoms perfectly.
When I drained the gear oil it looked like gold flake paint. With pretty metallic colors. I would drain the oil and see what it looks like. If it looks ok put fresh in and drive it for a while. If it gets louder then drain/check the oil again. Oil's cheap and you can kinda see the condition of that bearing that way. If you see any metallic flake in it you better think about pulling the gear stack and having a look. If it were me, I'd just pull it now and fix it. |
