I just had my rear main seal replaced and looked in on my mechanic while he did it.
He had a floor jack pushing a 1" steel rod with flat end up thru the engine support crossmember where there is a large hole, He pushed up on the crankshaft area on the front of the engine, after disconnecting the motor mounts, He got it high enuf to clear the pan out with no problem, replaced seals and back on the pan went, lowered the jack, reconnected mounts and all done. 4 hours total time.
Hope that makes sense
