Hi,
If the leak is truly the rear main oil seal on the engine, the only way to fix it would be to replace the rear main seal. This can be a big job.
I'm not sure what engine you have in the vehicle, but if it is the 6.0L, it is a one-piece seal and will require the removal of the transmission and flex plate/flywheel. See pic below.
Let me know the engine size, transmission type, and if it is 4w.
Take care,
Joe
