matt1900 0 Posted January 5, 2007 yo peeps. i've got an anoying rattle from the gearbox area. when i put my foot on the clutch pedal it dissapears. i sort of assumed it would be the release bearing, but i asked my mate and he said it was more likely to be the input bearing in the box. anyone got any experience of this, and anyway of determining what the cause is. dont wanna strip and rebuild to find it's still bloody there. (which is a typical outcome when i'm involved!) ta matt Share this post Link to post Share on other sites
Richie-Van-GTi 70 2 Cars Posted January 5, 2007 Id say release bearing, input bearing would more likely get louder under load. Share this post Link to post Share on other sites
welshpug 1,626 Posted January 5, 2007 I'd say input shaft, if the noise goes when the clutch is depressed (i.e when you isolate the gearbox from the engine) the noise from the input shaft isn't always that loud so under load theres more noise from elsewhere to notice it. but even if you do strip it, you should put a new clutch on anyway.

luggy 13 Posted January 5, 2007 Change the crank seal and get the flywheel skimmed as well. Share this post Link to post Share on other sites
ablister 31 Posted January 5, 2007 yes, i agree with welshpug, sounds very much like the input shaft bearings. If the noise was to get worse when clutch is pressed, then it's be the release bearing Share this post Link to post Share on other sites
Miles 331 1 Cars Posted January 5, 2007 Sounds more like the release bearing too me, These quite often make sounds like that Share this post Link to post Share on other sites
Guest purpletoddy Posted January 5, 2007 Sounds more like the release bearing too me, These quite often make sounds like that Have to agree mate.....ive changed a few of the bearings/clutches because of the release bearing being capoot......sound like the symptoms your describing Share this post Link to post Share on other sites
Guest michaelreddo Posted January 6, 2007 Have you tried tightening the clutch cable to make it tort on the input bearing arm?? Share this post Link to post Share on other sites
ablister 31 Posted January 6, 2007 Sounds more like the release bearing too me, These quite often make sounds like that Surely if it was the relase bearing, the noise would get worse as the bearing will be under load Share this post Link to post Share on other sites
Richie-Van-GTi 70 2 Cars Posted January 6, 2007 no, the bearing is pressed firmly together when you press the clutch so the noise goes away, lift off and its free to wobble and rattle. Share this post Link to post Share on other sites
pug_ham 242 3 Cars Posted January 6, 2007 Surely if it was the relase bearing, the noise would get worse as the bearing will be under load I've had two release bearings die, on both the noise got worse when you pushed the clutch pedal down. IIRC when the idler gear went on my old 309 SRi the noise disappeared when you pressed the clutch pedal down. Graham. Share this post Link to post Share on other sites
matt1900 0 Posted January 6, 2007 ok cheers for the input lads. i'll deffo get the box off and do the clutch and release bearing. is there any way to check the condition of the input bearing with the box off and how easy is it to change? ta matt Share this post Link to post Share on other sites
welshpug 1,626 Posted January 6, 2007 turn it by hand with the box in neutral, you should be able to feel roughness if the bearings have gone i believe, check for endplay too. Share this post Link to post Share on other sites
ablister 31 Posted January 6, 2007 (edited) no, the bearing is pressed firmly together when you press the clutch so the noise goes away, lift off and its free to wobble and rattle. Nope, the noise gets worse when under load. I've replaced numerous release bearings for the same symptoms. If input shaft bearings are away, the noise goes away when clutch is engaged as the drive is broken between engine + gearbox Also, the release bearing does not wobble + rattle when not in use Edited January 6, 2007 by ablister Share this post Link to post Share on other sites
