OIL SEALS
Check 0il level on plastic hubcap window. Do not overfill. Check oil level before each trip and
inspect for oil leaks. It is recommended that any time the hub is removed, that the complete oil seal
be replaced. Use gear type oil, SAE 80WE-90. Change oil, inspect bearings, and clean all parts in
hub at 50,000-mile intervals.
NOTE: When replacing oil with grease, consult seal manufacturer for proper seal and
hubcap that is compatible with the selected grease.
