Leaking axle seal 8 3/4

Well I'll add in my two cents after doing this last week for the first time and running into a bit of trouble. Before you pull the old seals measure how far they are in from the flange so you know when the new ones are driven in all the way. I didn't and thought one was all the way in an it was not. Thanks to the guys here i found my mistake.

Very good tip here.
And to add on to it.
After getting the measurement of the seal,take out the axel.
There will probable be a groove on the axel from the seal.
When your ready to install the seal,install it either a little closer or a little farther inside the housing. This way you get a clean portion of the axel to line up with the new seal.Were talking milimeters here.
Hope this makes sense.
