Throw out bearing noise when cold
catgut Mon Jan 05, 2009 3:16 pm
Do any of you experience this? Only makes noise when cold & depressing clutch pedal. Mostly during mid-travel. Goes away after warmed-up >10 minutes. Mine just started yesterday morning with all that rain. Anyone?

Same here not loud but just noticeable, even my Miata was the same way, as well as Nissan Frontier.

Update: Didn't hear it this morning. I wonder if it is moisture related...I'll have to take a look under the car to see if there are any holes/access points to the bell-housing.....hmmmmmm 
Hey! just thought of this. I think it is hard rain related: This morning was wet but seemed like it just drizzled = no noise. The morning it happened <Sunday AutoX> it was raining like mad <horizontal rain>. I think the water entering the intercooler hood scoop is dripping onto the trans bell-housing (car is parked aside the curb). So, moisture probably getting between engine/trans and possibly light surface rust occurs over a short period or washes out some throw-out bearing lube
so upon next start-up/use it squeals until the remaining lube gets distributed in the bearing again or the light surface rust scuffs off from use. I wonder if this holds any truth? Ideas anyone? Service bulletin?

That sounds about right Jess, like my brakes when it sits a while it turns brown and it not even raining, just that morning mist, also I noticed when my e brake is locked over the weekend and ready to drive makes a loud noise. So maybe Jess but I will be on the look out. Good theory though Jess!!!!catgut wrote:Update: Didn't hear it this morning.

Your brake pads are just high Mu <high friction; high metallic content> so naturally the trade off for awesome brakes is oxidation regardless of rain (on Guam anyway with 70% + humidity!
) can we trade? I'll swap you for my noisy throw-out bearing!?!

I think you might need some muffler bearing to solve that problem or some head light fluid

UPDATE:
No noise lately from this possible culprit bearing It hasn't really been raining hard lately either so again, this could be a determining factor.
Will post if conditions change.

maybe it will rain on autocross day, or whenever you just finished washing and waxing your car!

Thanks for keeping this thread alive Jhay 
My throw-out bearing is still noisy only during cold morning starts. Still goes away after a few minutes of warm-up. Kinda irritating for a newer car.
No time to bring it into Prestige to take a listen.

Update: 15k miles or so and it's still there during cold/cool starts. It's not as loud as before but def still there for a couple minutes. I'll be bringing it in for Prestige to take a look at in a bit but I think it's just a dry throwout bearing OR moisture sets in and does its business until driven and lubricated from operation. 
Weather definitely plays into this
