Can you replace the main seal on a 5.4L Ford Expedition?
Can you replace the main seal on a 5.4L Ford Expedition? Ive done many rear main seal jobs in my day but never a 5.4L ford. Looking at a fsm I see reference to not only a rear main seal but a part called an Oil Slinger, that mates to the rear main seal. FSM says to replace both the seal and the slinger. I see that main seal every where but no mention of an oil slinger not even at ford oem sources. What is a rear main oil seal? The rear main seal is what seals the crankshaft...
