Gaskets - always replace used gaskets with new gaskets. Never use the same gasket twice. Be sure that gasket holes match up with holes in the mating part.
- Serious damage to the vehicle can sult if any holes on the flanges are blocked by the gasket.
Lip type seals - Lip seals are used to seal oil or grease. To seal in oil, the lip is installed facing toward oil to be sealed. To seal grease, the lip usually faces away from grease.
- Seals should not be removed. Only remove seals to get at other parts or if the seal is damaged or worn.
- Leaking oil or grease usually means that a seal is damaged and needs to be replaced. Replace leaking seals so that bearings don't overheat. Do not use the same seal twice.
