Leaking Pinion Seal...8-3/4 ???

Could someone who's done one before tell me how difficult it is to change a pinion seal on an 8-3/4 pumpkin?

Mine is leaking like a sieve..........pain in the posterior.

I wouldn't think it'd be too bad a job, BUT with these, you never know. I thought it was leaking around the bolts......but after a close inspection, I found it's running out of the seal behind the yoke, and dripping off the bottom........faked me out.

Help me out here....... Hard to remove? Easy? What's up ?
