Help!why is fluid comming out my diff breather?

[buddha]

First off,this hasnt been addressed before,i checked the archives.

Just before xmas i had 4.56 ratios and front and rear Arb air lockers installed in my 96 cherro.
Since then(have not done alot of driving)i have had diff fluid comming out my rear diff breather.When it seems to get hot i can sit in the driveway after driving it and within 5 minutes i have a dinnerplate size puddle of diff fluid.
Had the diff breather hose changed the other day from a 40cm one to a 1.2 meter one and a new breather put on top.
Now the oil doesnt come out anywhere near as much but it still does come out and im sure this is not meant to happen(AS IT NEVER HAPPENED BEFORE ).
Jeep goes back to the diff shop on friday and im sure they will this time take off the diff cover and actually have a look inside.
Its had the fluid changed 3 times since being done cause it was loosing so much and it hasnt been over filled.
Any suggestions?
