IMPORTANT: Do not remove the forward gear ball bearing or the lower driveshaft ball bearing from the gear housing unless
replacement is necessary. The removal process may damage the bearings.
IMPORTANT: If the forward gear bearing and the lower driveshaft bearing are removed from the gear housing, inspect the gear
housing for signs of the bearing race spinning in their respective bores. This usually occurs as a result of bearing seizure from
lack of lubricant or from water intrusion. If either bearing spins in their respective bore, the gear housing must be replaced.
1. Inspect the lower driveshaft ball bearing for roughness. If necessary, remove the bearing by driving the bearing downward
