I added the part numbers for all the rear end seals in the cross reference except the front main seal. There is a square O-ring and an inner and outer axle seal in addition to the front main seal.

But like Kev said, if it's only leaking a bit and the seals aren't ancient you can just top it off. Could be worth checking for axle leaks though—just take off the rear brake drum.

I assume 80W90 EP gear oil is appropriate since the manual calls for 90 weight, or 80 weight in subzero weather.
