Input Planetary inspection.

Inspect the input planet captive thrust bearing assembly. To check the captive thrust bearing in the planet carrier (662) for wear, place a bushing or an output shaft sleeve (690) onto the bearing race and turn it with the palm of your hand. Do not touch the pinion gears. Any imperfections will be felt through the bushing.

Check the input planet pinion end play. The end play must not exceed 0.61 mm (0.024 inch).
Inspect the input carrier for pinion gear damage, proper pin stake and keystoned pinion gears. Pinions must rotate freely.

Check Input planet annulus gear/internal gear for damage (arrow).

The Reaction shaft is snap ringed into the Annulus gear, If you buy the AC Delco update kit....No need to inspect this part (The kit come with a new one), If you are going to reuse this part...Check for wear on the shaft from the Reaction sun gear bushing & for spline wear form the annulus gear.
