Life is not good. My brakes got grabby and I saw oily stuff on the lug nuts. I assumed it was the wheel cylinders. After finally getting the drum off I see that it's the oil seal. 
Can someone give me a brief description of what it takes to do this job? Do I need to open the diff cover and get at this famed C-clip to pull the axle out? What else?
