Manual Transmission - Noise coming from bellhousing when clutch peddal is depressed.
01-27-2005, 09:55 PM
I have a 99 Formula 6 spd with 77K miles. Whenever I push in the clutch peddal there is a chatter coming from the transmission that sounds almost like a bad wheel bearing. At times it feels like the clutch is not fully dissengaging because I will have trouble getting into gears. I can feel a slight vibration through the shifter as well when the peddal is in. Could it be a bad throw out bearing or is it probably something with my hadraulics?
Also, would GM PART # 12570806 (DESCRIPTION: FLYWHEEL package
this flywheel package comes with the following: flywheel, pressure plate and clutch disc.-----this kit is designated for 2001-2004 corvette Z06 equipped with the LS6 engine with MM6 trans.) with an f-body throw out bering and pilot bearing work for me?
Thanks for any help.

It is likely a throw out. The LS^ clutch is OK for stockers. You can upgrade from there. Dont forget to replace the pilot bearing.

Mine was a wasted pilot bearing. Their a needle bearing design and all the needle bearings were gone! :confused: :eek2:

I would say pilot bearing too. Exact same thing happened to me. I ended up having to replace my input shaft cause the broken needle bearings chewed it up.

another vote for pilot bearing. Don't mess around and get it fixed. It can ruin your tranny.

Thanks for the advice guys, I just moved to an new apatment so I haven't had the internet for a while so I just got to see this. I ordered the Z06 clutch kit, the upgraded slave cylinder with TOB and a pilot bearing, should be replacing it all next weekend. The problem seems to come and go, its not as bad in the mornings when the car is cold.
Do you need a special tool to get the pilot bearing out? And hpw do you disconnect the quick disconnect line that goes into the slave?
Thanks again for the help.

Yes, you will need a slide hammer or pilot bearing puller or to make your own tool to get the pilot bearing out. I ordered a pilot bearing puller from jcwhitney and dremeled it down to fit. I've used anything from 2 screwdrivers to needlenose pliers to unhook the quick disconnect but i've heard a die grinder wrench works good.

Thank you, I'll try to rent the pilot bearing puller from auto zone to save some cash. I just got my car and haven't really inspected that line yet, but on the ford clutches I have done the connector required a special tool to disconnect it. I am assuming that the quick disconect GM uses for the slave is similar to the ones they used for the fuel lines that go to the fuel pump assembly?
