I was doing ball joints and thought I would change out the drivers side dif seal. On an independent front suspension it comes out from the wheel side, quite a challange to get out. It was the original and had been leaking around the axle for 100ish years. I included the pictures if the upload worked. Napa has the seal, others looked at me like I was an alien when I asked for it. One picture shows the new and old seal after, the other shows the axle housing after I removed 25 pounds of old grease with impregnated gravel, dirt, leaves and mouse crap.
