I have a 1999 Arosa 1.0. Recently the gearbox seems to have failed - there is no drive to the wheels. Both driveshafts appear to be working fine, the clutch is behaving normally. So having selected any gear, and releasing the clutch, there is no drive to the wheels, just a sound/feel as if a shaft is slipping in a worn spline.
Having jacked the car up, with it in gear, the road wheels can be turned by hand - with a similar 'shaft slipping' feeling and noise. It is the same for both sides.
Is this likely to be a case of the riveted final drive bevel gear failing? Any ideas?
Thanks.
