Rear Axle leak

[1pcguru]

I searched the forums and I could not believe this was the first post but here goes. I gotta pretty significant leak from my rear diff since the last time I went wheelin'. It looks as if it is leaking from right behing the driveshaft in front of the axle housing. I was wondering how hard it is to repair the seal or should I just be pricing a new axle housing.
Thanks in advance.

Sounds like the pinion seal. You can replace it yourself.
