Before installing the new YK8081 13T Spider Gears (80037) in your YK8081, a key precaution is to inspect the sun gears and the differential case for wear or damage as well. The YK8081's drivetrain features steel gear construction, so if one component has worn, others may also need attention . During installation, ensure the spider gears are properly seated and lubricated with diff oil to prevent premature wear.
