So I went out this morning to make a run to the store to buy some holiday cookies and noticed a large puddle of oil on the floor under my beloved XJ. It seams to be leaking out of the front differential on the drivers side and puddling right at the front tire. I am sure that there is just a seal that needs to be replaced. My question is does anyone know the part number of what I am looking for? Autozone seams to not be able to find what I am looking for. I don't want to tear her appart until I have the replacement parts in hand as she is my daily driver. Thanks for the help everyone!
