No need to open up the front diff but I did end up having to drop the front diff after unbolting the cv axles from the flanges.
It just makes it easier to remove the flanges and the seals.
Once you've got the diff out, just pull on the flange(s) and they'll pop right out. The circlips are on the end of the flange shaft.
The reason why it's good to change the flange seal at the same time is because when a flange works its way out, the seal can get deformed.
To remove the seal, I bought the same tool Pops had recommended, less than $10 from Advance. Makes it quick and easy.
I remember reading a thread over on TT that explained how to drop/replace the front diff.
