Squeal when leaving a stop - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Anderzz · 10-29-2018, 08:54 AM

Interested on people's thoughts on an issue I'm having. Clutch was swapped less than 3k miles ago to a Southbend Stage 3 Enduro with a 2017 OE TOB, Motul fluid.

When leaving stops I currently get a weird squeel at the very top of the clutch engagement before moving. Sound is brief, variable, but is considerably different from a TOB failure sound.

Any idea of potential culprits? Originally thought it may be a wheel bearing going as it sounds like something spinning is causing it but it doesn't correlate to wheel spin.

Any insight is appreciated

I may be wrong here, but I think it's the flywheel that starts squealing. Did you take a peek when swapping out the clutch? The same squeal happened to me in my previous car and when I went to change the clutch, the flywheel was pretty bad. Sometimes you can get away with resurfacing but I had to get a new one. Squeal was gone after that.

Is it only when you start from a stop? Or anytime you release the clutch? The clutch fork could be squeaking where the slave cylinder hits it, or on the pivot ball. Try greasing those areas if you haven't.

When the clutch was swapped out we dropped in a brand new exedy flywheel as well so I would be surprised if that was the issue.

Only from a stop.

I have to release the clutch around 95% and then right as its catching there's 1-3 seconds of variable squeal.
