• If a new driveshaft is installed and the factory marking on the rear final drive flange is no longer visible, check radial runout at flange/driveshaft => [ Radial Run-Out at Flange/Driveshaft, Measuring and Marking ] Procedures and adjust color marking at new driveshaft to new marking at flange/driveshaft.
