overfilled differential.

[Rukus]

I just had my car at Mr. Lube to check the air pressure, and i went underneath and i noticed that there was some slight leakage from my axle seals. I was like "well that sucks" so i then asked the guy there (my friend) to check the diff oil level and i had overfilled it.
I read on the net that overfilling your diff can press out the axle seals. If my seals are leaking, i most likely need to replace them now? They aren't leaking fast, i am sjut worried about dirt getting into the diff.

Anyone know the fluid capacity for a 3.91 LSD differential? (out of curiosity)
I als have NO IDEA how i managed to over fill it either, since the car was SUPPOSED to be on level ground.

Do you think i need to replace my seals ASAP, or can it wait til next summer?

How did you overfill your differential? How can you get the fluid level higher than the fill hole? Is your vent clogged?

i dont think its possible to overfill it if you followed the right procedure.
if the leak is not bad, you might be able to hold out. ...wanna sell your diff?

I told you guys, i have no idea what happenned.
Actually come to think of it, when I installed my diff, i DID notice that my rear of my car seemed unusually high, when i pulled it off the jackstands and onto the driveway. I forgot about that. Why would have it been like that? (and ishould have known better if i thought that)\

The issue here isn't how I overfilled my differential. Discussing how i did it, isn't gonna make that fact That i did do it go away. Its about my axle seals and what i need to do with them.

i dont know the capacity of the small case diff. the large case takes 1 and about 3/4 quarts.
if it were mine id get it level and drop the fill plug. let it run out and put the plug back in. if you havent been driving it for a long time id think your seals will be fine. drain it, clean the axle shafts off and watch it to see what it does.
