Re: Why do my throw out bearings keep failing?!

You MUST have a bit of play, some slop. Perhaps, you are trying to get the clutch all the way to the top. As the clutch wears, it chases the "pedal" to the top until it actually passes top (never lets go of the throw-out bearing and never fully engages the clutch, leading to a slipping clutch.)

Check adjustment. If the throw out bearing is always touching the pressure plate it will wear out the bearing prematurely due to the fact that it is always spinning.

Assuming you're greasing the bearing enough, could the shaft that the bearing rides on be worn? You can get a steel version to replace the stock aluminum one, if that's the case. Otherwise, maybe the cable isn't releasing the clutch completely and it's always spinning the bearing?

I've heard that the "casing" that holds the bearing in place is some sort of plastic. You can buy a steel replacement from Ford, it's suposed to fix that problem.

I agree. I solve alot of chirps by simply re-greasing the pivot point of the clutch fork. If it runs out of grease for an extended amout of time it gets worn out and does need frequent re-greasing...

By the way, use hi temp grease...

Hope this helps,

Do you sit at stoplights with the clutch in rather than putting it in neutral? I am told that this will cause excessive wear, but I doubt it would be THAT excessive!

It might be the retaining ring for the bearing too... or the clutch springs so says my hubby..because he has the same problem on his old F-250, he's just not wanting to change it.. again.

Looks like I just had it misadjusted. I adjusted the firewall adjuster and am going to see what happens for a while. It's greased pretty well. And I already have a steal bearing retainer in there. Thanks for the reply.
