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? |

Is that a Lola? Group: Members Posts: 1,523 Joined: 2-June 05 From: Little Rock, AR Member No.: 4,188 Region Association: None |
Yup. It's gotta be pulled apart. The bearing above... now THAT was makin' some racket. When the pinion bearing gets loose it compromises the R&P contact pattern as the pinion is forced away from the ring. Bad carrier bearings can do the same thing by allowing the ring to wobble and be forced away from the pinion.
Good luck |

Good luck (IMG:style_emoticons/default/agree.gif) Just my $.02 but this sounds like what mine was doing with one of the ones I rebuilt and it turned out to be the bearing! |
