I have just been told that the differential in my gear box has 'broken up' and that this is quite a common rover problem. I've done less than 60k miles which seems short for a gearbox life. To get it reconditioned and all sorted is over £700 and thats not at a dealer. Anyone heard of this before? If its a 'common Rover' problem is it worth trying to get them to cover some of the costs??
