Throw out bearing?

I would have thought it was the opposite as the bearing only comes into play when you put your foot on the clutch?

Notso

had a ute once that only rattled when the clutch was out......go figure?

Notso,,You are quite right,with the clutch depressed you will get noise as the bearing is then under load. When the clutch is out the bearing is just sitting there but sometimes will rattle if it is loose on the clutch fork or has some wear. From the symptoms stated on the post I would say the problem is with the spigot bearing in the flywheel.

Cheers for the info. Foxhound if it is the spigot bearing would the probelm be fixed with a new clutch kit?

The spigot bearing is not supplied in the clutch kit but can usually be obtained from a bearing service and only cost a few dollars. The gearbox and clutch have to be removed to replace this bearing so it would be advisable to closely inspect the clutch and throw out bearing and renew same if there is any doubt with them. The spigot bearing only operates when the gearbox is in gear and the clutch is being released. As soon as the clutch reaches friction point the bearing becomes stationary as the gearbox output shaft that is located into the spigot bearing and is splined to the clutch plate becomes one with the flywheel.

Mark, the noise you describe happens when the thrust bearing wears a groove in the forks of the diaphragm spring on a vehicle that runs with zero freeplay. The bearing is good, but the groove causes the noise when the pedal is up. Typical of Toyotas.
