    Ok, so my throwout bearing has been going for like 2 months now. With the clutch engaged, you can hear the deep rattling that stops when you disengage it. It doesn't ever grind, but the car just seems to go into gear kinda rough after it's warmed up. I have a couple questions...
    What will happen when the throwout bearing kicks the bucket?
    A new clutch was installed with this bearing 8k miles ago and it's already bad... What could cause it to go out so fast?


    Thanks in advance,
    Sean

    Motor was completely rebuilt and has since had 8k miles on it. The old tranny was already having problems, but I put in a new clutch and throwout bearing in when assembling the car. The old tranny went out on me while on the freeway(It jammed, car wouldn't move with clutch in). 4k miles ago is when I installed the current tranny that had 50k on it(legit). It has since had 10w40 synthetic motor oil in it filled to the top from the speed sensor hole and hasn't lost a drop of fluid to this day. It seems to distinctly be the throwout bearing judging by the sound and how it stops when the clutch is disengaged.

    It's only only like 6 hours of work. I remember I fucked up the TOB and I finished it before dark.
    Worse comes to worse, you have to do it all over and replace the tranny.

    This may sound cocky, but I can replace said bearing in under an hour with a lift. I'm just trying to figure out something I may not know before I take the tranny off. Something that may make it go out so fast that I can look for while I'm in there. The tranny itself is doing its' job fine, except the shifting getting slightly rougher at times(Which is probably nothing at all). I don't exactly have another few hundred bucks laying around for a tranny, don't jinx me please =(.

    Not cocky at all, I'm talking about with a floor jack and stands. It's very possible to do it in an hour with a lift and some good air tools.

    You might have gotten a faulty TOB. It;s happened to me before.

    Ugh, may have found our problem right there.... I didn't cover it in grease. I'm also drawing a blank on the clip, I'll find out when I tear it apart. Thanks a lot.

    Make sure your clutch is adjusted properly. the release bearing is not supposed to be engaged at all times, it is supposed to be completely free of the pressure plate when it is disengaged. Sometimes over-slipping a clutch will cause this premature failure or excessive contact with the pressure plate. When the clutch begins to wear down, the clearance between these parts change. Might as well replace the whole clutch setup and re-surface/balance the flywheel and install a new release bearing (throwout bearing).

    The answer to your questions is simple; Its your driving. Just for reference, you do have to break in clutches. 500 miles is usually the norm.

    Fuck it while you crack her open, throw a lighter flwheel in also. 11 pounder would be my choice.

    Yeah, I figured some odd driving methods could have had something to do with it. My exhaust gets WAY too loud at certain RPM's, so I find myself shifting too early a lot of the time. I'm not a bad driver, but it is possible. Maybe it just wasn't adjusted right in the first place =/. Great advice/point.

    Thanks

    it will do that if you ride the clutch also. just try to keep an eye on how you are driving.

    Shifting too early won't cause bearing failure, its actually easier on the bearings. There are many different causes of bearing failure/early failure. An unbalanced flywheel is one that is common today.

    Your welcome.

    would having 4 outta 5 flywheel bolts holding the flywheel on cause the same type of failure? ;)

    Unless that one bolt that is missing causes an imbalance, I would have to say no.
