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? |

So:
- the noise is present when the pinion is moving the fastest; 4 and 5. - Increases with pinion speed - It worsens under load = putting power to the pinion gear. Looking like a bearing like Jake pictured. This can lead to badness if left alone. Replacing the R/P is not that expensive as I sell good set for $50, then the labor to install them. BUT, rebuilding a used core is more economical and you usually get some good parts in the core to save $. If I can help, let me know. I wish I had better news, but based on what you are describing it is not so. |
