Oiwa Garage Tech Note

"This is the rear main seal. Reaching the rear main means separating the transmission, so do it during clutch work. Drive the seal square and lube the lip so it does not tear on the crank."

Frequently Asked Questions

How do I know the rear main seal is leaking?

Look for oil building up between the engine and transmission and a drip that shows after the truck sits. If the front seals are dry but you have a leak at the bellhousing, suspect the rear main.
