What throwout bearing?

I am starting to get the annoying chirp chirp of a bad throwout bearing. Right now I have a hays 70-201 installed it lasted about 4 years. Any suggestions on a new brand or should I just stick with hays?

Re: What throwout bearing?

For throwout bearings I have heard the centerforce ones are good. N1401 i think. Its the vette bearing supposed to be a bit better.

I went steel after reading some stories about aluminum ones wearing funny. You also need a shim kit. I know the link says mustang, I called them and they set me up with a GM one/

Re: What throwout bearing?

The new Hayes bearing is already squeaking 2 years in about 3K miles.
Maybe I'll try center Force.

Has anyone tried the ACDelco gold? Or is it cheap Chinese crap now

Re: What throwout bearing?

One thing i noticed is centerforce may use a generic bearing that looks identical to other brands; as many brands. It is indicated by comparing the stamped multidigit model number in various photos. All look identical in stamping placement and font.

Not saying it is bad, or even correct But same bearing may be priced better elsewhere.

Re: What throwout bearing?

I am needing the same answer. I was about to order this: GM Genuine Parts CT24KVAL but wasn't sure if it was a good one or not. It's probably a Timken or National rebranded.
