Have had a Mira Classic for about 6 months now but have sarted getting an intermittent whine. It sounds like a bad diff whine and only lasts for a couple of seconds when you accelerate. It also appears to be leaking oil from where the gear selector comes out of the bottom of the 'box (I have been topping it up though!). Anyone experienced this or know anyone in the South-East who could carry out gearbox repairs, I fear it may be a bearing making the whining noise, and that's way beyond my capabilities!
