If you are not replacing the front bearing and/or rear bearing, go to step 15. Clamp the rotor in a soft-jawed vice, then remove the pulley locknut. Remove the rotor using a puller as shown. Inspect the rotor shaft for galling, and inspect the bearing journal surface in the drive-end housing for seizure marks. If either the rotor or drive-end housing is damaged, replace the alternator. If both the rotor and the drive-end housing are OK, go to step 10.

Remove the rear bearing using the puller as shown. Use a hand press to install the new rear bearing. Apply pressure only on the inner race to avoid damaging the bearing.
