clutch bearing?

throw out bearing is another one i heard. when i start the car, it idles just fine..but it rattles. but when i push in the clutch, the rattling goes away. how difficult is it to replace it? and if i dont, will there be any long term consequences?

You'll have to pull the trans.

Any vibration associated with rotating mass is bad (the vibration will eventually lead to ancillary components failing). If this is prolly true with TO bearings, which affects the input shafts and gear box. Remember, the vibration goes away when the clutch is engaged, meaning it's rattling away while you cruise on down the road...

craaaap. im assuming it would take give or take a full day to do the job right? can i purchase the clutch bearing separate?

EDIT: just re searched bav auto and they're asking $34. is that reasonable? sounds pretty cheap.

I don't know how long it will take you. I've heard the top two bolts on the bell housing are a supreme pain.

alright, thanks man i appreciate it

whats weird is that when i bought the clutch kit from bav auto (the complete kit) it came with a brand new throw out bearing. ive had the car since April of this year. do they tend to go out, or break easily?

ive messaged my mechanic about it as well since he helped me build my e30.

my recomendation is you do the entire clutch and clean it up....as long as you are in that far might just as well do the entire thing...good luck cliff

well thats the thing thats making me scratch my head..the clutch has only been in there since april of this year. one recommendation is that i should use Royal Purple or whatever inside? i bought the whole kit from bav auto for 239..so im not sure why its making this noise?

Royal Purple is good, but doesn't affect the clutch at all. You should call BavAuto and relate your experience. Maybe they have some insight into why the TOB went south so quickly.

thats weird, why would someone tell me to put Royal Purple in...and it'll make the problem nearly go away? haha. people these days.

thanks for the tip, ill try giving them a call tomorrow to try to sort this out. does this mean the TOB broke, or just isn't functioning correctly?

typically it'll be most apparent with the clutch engaged with the tranny in gear....you do understand what the throwout bearing does right? cliffmac

when the tranny is in neutral and the clutch is not engaged with the engine running, does the car creep forward? and still make this sound? cliff

ive done some reading on it before i posted. and when i push in the clutch (in neutral) the sound is normal, when i let it out..it starts rattling

nope. it does not creep forward. it just rattles when the clutch is not engaged.

When you do pull the bell housing, you will need to stock up on socket extensions and patience. It seriously took me 3 socket extensions and one of those flexible elbow joints to get a socket head on the top two bolts. Maybe there is a better way or a special tool for it, but this was my experience.

haha, ill keep that in mind. i just need to find time to do this. and a person who is relatively mechanically inclined so they can help me.

i find this odd..i know this is an online forum (obviously) but all the e30 enthusiasts on here are really far away from each other. it sucks because one just cannot stop by for the evening and help out or just hang ya know. its a bummer.

i just realized..mine has been doing this basically ever since the clutch was installed. maybe he didnt do it right? but thats horrible man! i feel your pain. no fun at all

From what I've read, your experience is typical. Some people have unbolted the motor mounts and lifted the back of the engine in order to gain access to those bolts. I would go the socket extension / u-joint route.

Does the guy stand behind his work? Any chance he will fix his mistake if did screw up? Worth asking, yeah?

I feel your pain...I live in del rio, TX and am far away from everything...except Mexico. I can see that from my backyard.

hes a pretty reasonable guy. he does bmws as a part time thing, just for his own fun..not to really make any money. and ill probably have to pay him, even though he might have messed up. ill try to talk to him about it. i emailed him yesterday a little after i started this thread..no response yet.

if it's that new of a clutch kit from BavAuto that is interesting....hmmm....who installed this?

a buddy of mine who has been working on bmws for years now. old and new. 3s, 5s, 6s, 7s.

cause usually BavarianAutosport is spot on....and a clutch involves many other activities that may cause this...just a guess....cliffmac

thats what im thinking. i think the rattle has always been there. i cannot remember WHEN it started, but it was maybe 2-3 months (or sooner?) after my car was finished that i noticed it.

I agree it sounds like the clutch bearing but have you elimiated the shifter? I know loose or worn bushings cause a good amount of vibration. Also, how does the clutch pedal feel?
