how do you replace a Ford F150 rear axle seal
there should be an axle code or the door jam. Then you can call your local ford dealer and the can tell you, but some of the owner manuals had a list of the axle codes in them.
Could be any of several. Check the little metal tag bolted to the diff. That truck also likely has a 8.8 rear, not a 9 inch. If the tag says "88" it's an 8.8. The gear ratio will be stamped with no punctuation, i.e. "327" would be a 3.27 gear.

behind rear seat
The tag on the cover, bolted to one of the 10 bolts on a 8.8 rear, should spell it out for you. My Mustang GT tag reads 3L08 88 4B07. The first three numbers on the tag tells me its a 3.08 gear ratio. Assuming you are referring to a F150 with a 8.8 rear, Ford used the 8.8 on a bunch of cars and trucks.

its located at the rear drive axle

Either your brakes are sticking or they are adjusted to much.
