I need to replace the bearings in the rear diff or alternatively replace the diff with a reconed one. In addition I want the gearbox to be serviced / oil flush. The haldex unit on the diff is still ok and wouldn't need to be replaced with diff. This car has low mileage and I would like the job to be done by someone that can guarantee the repair. I also need to change the cambelt soon, kindly qoute me seperately on that?
