Clutch squeal in '08 WRX -Only at point of engagement
I have a '08 WRX wagon with about 10k miles on the odo.
It recently began making a quiet yet noticeable 2 to 3 second squeal when I engage the clutch in first or second gears.
It only happens when the engine is cold AND the outside ambient temperature is below 55 Fahrenheit. It stops almost as soon as the temp gauge gets above the "C" mark.
It sounds a little like a nest of bird chicks on speed.
It’s clearly coming from the clutch mechanism, or possibly the transmission.
It occurs for one or two seconds only at the point in my raising the clutch pedal where the clutch is beginning to engage; it sometimes persists for another second or so after it's fully in gear. It only happens in first and second gears.
My dealership's service department replaced what they felt was a defective throw-out bearing. Nothing else seemed, to them, to be defective or atypically worn.
They likely didn't test it after the repair, because the problem was there again for me the next morning at the first cold start. It seems to be getting progressively louder and longer in duration. Process of elimination: So we know it wasn't a throw-out bearing.
Someone suggested it may be an issue with the clutch hydraulics (which makes sense in light of the temperature sensitivity). Could it be normal? Does anyone else with an '08 manual have that issue?
Someone else suggested it could be a synch gear. (If so, should I just wait for it to fail?)
Any other ideas? I'd like to have some insight into what it may be before I let the dealership service department tear anything else apart. I'd primarily like to know if this is something benign I may be able live to with... or whether it indicates a broader problem with further potential complications (which I'm afraid of).
