Front pinion seal.
Katt ,
Before you replace the seal check to make sure the vent hose isnt blocked . Have you been running it in 4wd or is it just leaking w/o using it in 4wd ? If you do have to replace the seal , you have to establish the pinion bearing preload before you loosen the nut to remove the yolk . Then its just a matter of prying the old seal out and installing the new one . Its very important you tighten the nut back so the preload on the bearing is the same ...this keeps the pinion and ring gear teeth in the same contact pattern and ensures the bearing isnt too loose or tight .
