    that would be your throw out bearing. i had the same problem in my 80 K5. im sure thats it by the way you describe it.

    Yeah, sounds like a throw out bearing. I'm not too familiar with a manual on a truck like yours, but usually they are replaced at the same time as the clutch. Also, since yours is a mechanical linkage clutch, check all that to make sure everything is in line. Does it still shift fine?

    Yeah thats what blows my mind is that nothing else feels out of place just makes lots of noise...shifts fine

    Sure it shifts fine, the release bearing is still there and working, it's just telling you it's getting ready to go west. Whne it finally locks up it will take the fingers off the pressure plate and THEN you'll have trouble shifting.

    Okay so i got a price on the part and all seems like a cheap fix...however looking in the chilton's manual the expensive fix seems to be the labor time involved....need to drop the t-case (which i need to labor on anyway) and then the tranny....sounds like fun...:rolleyes:

    As long as you have it apart, you might as well put in a new clutch too. That is, unless the clutch has a lot of meat on it still.

    definately! I can get a real deal on a new clutch set...one thing i question is whether to go with the regular clutch set or heavy duty set....that is if it seems to be worn

    There's rarely an instance where HD is not better than standard duty.

    Stay away from the borg and beck three finger style.
    Go with a hd diapragm. Just replaced one in mine that caused a lot of problems.
    just my two cents

    The down side of going to a HD clutch is you may experience a heavier clutch pedal and a more abrupt engagement. It will definatly last longer though. Depends on how hard you use your truck.Also dont forget to have the flywheel machined and replace the pilot bushing while you are their, as you probably dont want to duplicate this procedure.Good luck.

    yep it was definately the release bearing...that thing was metal on metal and looked to have about 5minutes or less in it before it went west...you aint kiddin when you want to get as much done in this shot to keep from havign to repeat the process

    This isn't really relevant to this particular thread, but I thought some of you might find this "definition" of clutch amusing:


    Clutch: 1} Mechanical or hydraulic friction device in a vehicle's drivetrain, used to stall the engine when starting on hills.

    2} What passengers then do to their seats.
