| Post subject: | Diff, gearbox or primary gear noise |
Been thinking about this for a while now, hoping someone can help (although I probably should know myself), my original 850 engine (reconditioned and in good condition) but it has this very loud whine. I remember my first mini, also an 850 was a bit whiny too, but nothing like this. You can hear it really clearly in this clip if you jump to near the end around 5:50 where it’s taken from outside the car. It was really loud inside though and through every gear under load - both backing off and accelerating. Just wondering if it’s diff, gearbox bearing somewhere, or primary gear. I would normally say diff, but not sure on the mini. https://youtu.be/Nb0IUrY0u-w |

Idler gear would be my bet. If its bearings go they can destroy the gearbox case or flywheel housing. |

Thanks drmini, the engine is out so will have to do a strip down, but at least I’ll know where to start. Big learning curve coming up for me. |
