Mini Cooper Countryman manual transmission transfer case output bearing failure issue on Mini Cooper Countryman

Some Mini Cooper Countryman owners report experiencing transfer case output bearing failure, which can manifest as unusual noises in the drivetrain, including whining, grinding, or clunking sounds. These symptoms may indicate underlying problems with the transmission or differential. Additionally, rough driving conditions and low transmission fluid levels are reported as potential causes of transmission failure, leading to gear-shifting difficulties. To mitigate these issues, some owners find that applying thick moly grease on the transmission output shaft during maintenance can provide added protection. In cases where spinning or knocking noises arise from the transfer box internal output gear and bearing, repair kits or replacement parts may be necessary to resolve the problem and ensure smooth drivetrain operation.
