Rear diff input shaft seal

[Robert Bade]

Hello, 


My rear diff, the input shaft, or radial shaft, the one that attaches to the drive shaft, it's seal has started leaking. I could find no mention of this seal in Bentley. I did find it in ETKA. Half shaft seal replacement only at Scott Miller's site. 

I can't determine if  this a relatively simple deal of pulling the cover/seal/shaft alone, or, does it require the bearings, etc. mentioned in Bentley to come out with the cover/seal/shaft and that whole assembly be rebuilt. I could find the seal and cover o-ring at qenuineaudiparts.com.

Anyone replaced this seal?

Thanks, Bob
