Gerbox Grinding noise |

Hi to all,
I have a grinding noise from gearbox on my Nissan march k11 year 1994, engine CG10 since 1 week. When I press the clutch pedal, it stop and when I release the clutch pedal it start making grinding noise. Today, I replaced the clutch release bearing and all bearings inside the gearbox. Unfortunately, the problem still persisting. I also checked all gears teeth for any damaged, all are good. No trace of wear on the casing. Anybody encounter this type of problem. |

the reason for most damaged gearboxes is leaking driveshaft seals half emptying box which I think affects the final drive diff first, is it noisy all gears, you have already gone further than most people dismantling and replacing your own bearings, you should do pictures
in Australia its cheaper and easier to get a new box |

Thanks Frank2 and Rudy,
I don`t think its thrust bearing as the engine run perfectly. Its only when I press the clutch pedal, the grinding noise stop. Therefor, the problem is the gearbox. I renew all bearings except the 2 side differential bearings. Does the 2 bearings could cause this noise?????????? |

No. When you are driving at full speed or slow, no grinding noise. Only on neutral you can hear it.
The car run perfectly. You know Frank, its same noise like worn layshaft bearing. |

Its true on neutral the diff do not turn. What made the grinding noise on neutral??? Big mystery!
I think I dismantle once again the gearbox and verify each parts thoroughly. What you think? |

is it definitely a metallic grinding/whirring noise or a rattling noise only at idle in neutral?
cos I just wrote a reply on another thread bout when my clutch plate spring once worn loose n rattled about. http://micra.org.uk/threads/gearbox-help-needed.59043/#post-652212 |

More than whirring noise. I renew the clutch release bearing, cover and disc. I put original parts.
