Grease comming out differential flange bolts?

[Xenocide]

After driving about 200 miles on my new e30 rear end, it looks like grease is coming out from the bolts on the differential flanges...I don't see how this is possible... On one side the great is flung up all on the underside in a perfect circle around the flange.

Any ideas???

Your output shaft seals are probably leaking.

My e30 differential was installed about 2 months ago, and has been leaking fluid from where the output falnges go into the differential for about a month. Not the same as with yours,... yours looks to be comeing from where the flanges bolt together, which makes no sense. Sorry I cannot help, I just felt like talking.

that would make sense if it was coming out by the differential, but its comming out past the flange.
