Intermittent Squealing noise when releasing Clutch

[greg0078]

01 996 Cab

 

Here is the scenario.  

When i release the clutch halfway and add some gas to the bite point some times i hear a squealing noise coming from the rear.  It does not do it every time and the car is a daily driver.  It seemed to do it more frequent when the weather got warmer, but some days it does not do it all.  

I had the clutch replaced in Feb 15 when they installed an IMS.  When they put in a new clutch, they installed a new flywheel kit also.  

Any ideas to what this may be?  Im hoping its not clutch related as I then have to go into the back and forth of them honoring their work.  I already called the shop and they informed me their is no warranty on the clutch repair, which i find unacceptable.  

Opinions welcome

Agreed that seems unacceptable, but probably something you should have asked about first.  Did they install a new clutch fork and release bearing?  I believe there is an updated version Unfortunately to replace the transmission has to be dropped again.

i dont know about the clutch fork or release bearing, but i did speak to another shop.  They also leaned toward the release bearing could be the cause, and its a standard part that is included w/ the clutch kit, so should have been replaced at the time of the clutch repair.  

 

I was kind of hoping it was a belt slipping vs clutch repair job, but thanks for the feedback and fast repsonse

Greg,

 

As the other members suggested it sounds (no pun intended) like a throw out bearing.  Usually any mechanic or even a non mechanic for the money will replace the throwout bearing if he gets within 10' of the clutch.  It's the cheapest part of a clutch job.  Do you have a work order that shows the parts that were installed?

 

Have you tried to isolate the noise by moving the clutch pedal in and out...  Sounds like you got a bad shop that won't even discuss your problem.  Let us know what you find...

 

Good luck,

It sounds like the bearing to me too. I had it replaced recently but the whole thing ended up to 3K and a full gear box rebuild after clutch was only 8K miles old and replaced on dealership.

Another data point.

I replaced the clutch disk, PP, TO bearing, Fork, and pivot on my 2003 C2 Cab while addressing a leaking RMS @~ 35k. 

The Sachs replacement clutch pack would occasionally squeal as yours does.  I went back in to do the IMS when the ceramic replacement part and procedure were first offered @~50k.  I replaced the disk at that time and never heard the squeal again.  So in my case I figured the squeal I heard was the disk. YMMV
