996 - Squeal from rear end when clutch it let out

[Flakarter]

Hello all:

I have a 99' 996, with about 64k on it. The clutch, flywheel, pressure plate, throw out bearing, etc., were replaced about 2 years ago, with about 50k miles on the car.

Within the past 3-4 months, in hot weather, there is a squeal coming from the rear end when I let out the clutch. It starts about then the clutch starts to grab, and stops when the clutch fully grabs. I even got it to make the noise once while going into 2nd gear. If I let out the clutch really slow or really fast, it usually won't make the noise.

The nosie goes away in cooler weather, and even in warmer weather, it is not present all the time. For instance, I'm in Florida, and it has not made the noise for the past 2-3 weeks, but started again today.

The local private mechanic I used thinks it might be something connected to the accessory belt, but why would it make the noise when the clutch is let out?

As the clutch was/is quite expensive to replace, I am hopeful that it might be something like a bearing in the alternator or something else connected to the accessory belt.

Any ideas?

Thanks! :D

Why not disconnect the belt (for a very period) and see if the noise goes away?

Genius! I'll do it! Or my mechanic will! ;-)))

Hi

Sorry to butt in.

Did you ever get the bottom of the clutch squeal problem ?

My 993 C4 has developed exactly the symptoms.

im hoping its a cheap fix

Hi Karl, I just posted this Friday, so no time yet to have it looked at.

A bad transmission input shaft bearing will cause a squeal or sound like a squeal.

Thanks Kevin, although I hope that's not the case! Sounds expensive!

I have this exact problem also. Alternator, starter, water pump and poly rib belt have all been replaced within the last 30k. All bearings spin free. 2003 996 c2 has 110k currently. I'm hopeful someone can help.
