Yep, they have one. 1986 and older has a two piece rear main seal. 1987 and up has a one piece rear main seal.
rear main seal is the gasket around the crank between the rear of the motor and the transmission. front and rear main seals are usual spots for oil leaks.
The engine rear main seal can only be replaced with the engine or transmission out of the vehicle.
You must remove the transmission are engine to replace the rear main seal.
You will have to pull the transmission out and remove the fly-wheel to inspect the rear main seal. It is a 1 piece round seal that slides over the rear of the crankshaft. If the rear main seal is leaking on that 2002, I would find that very odd.

You MUST remove the oil pan to change the rear main seal. It's the only way because it is a 2 piece seal that fits in the rear main cap and block.
You will need to remove the transmission.
