E: INSPECTION
Disassembled parts should be washed clean first
and then inspected carefully.
1) Bearings
Replace the bearings in the following cases:
• Bearings whose balls, outer races and inner rac-
es are broken or rusty.
• Worn bearings
• Bearings that fail to turn smoothly or make ab-
normal noise when turned after gear oil lubrication.
• The ball bearing on the rear side of the drive pin-
ion shaft should be checked for smooth rotation be-
fore the drive pinion assembly is disassembled. In
this case, because a preload is working on the
bearing, its rotation feels like it is slightly dragging
unlike the other bearings.
