New pinion seal. The plug for the diff is on the driver side front of the pumkin & takes a 3/8 square drive (ratchet or breaker bar). Just fill it to bottom of plug hole & make sure the vent hose on the diff is not plugged up with crud.

Thanks I didnt get to really look around at it as it was getting dark! I will take the vent hose off tomarrow and make sure it is clear. The tag on the pumpkin say synthetic 75-140 is that what everyone uses?

75-140 yep, look at tag & see if you have a limited slip diff...the tag will have LS on it.
If you do have a LS you will need to add friction modifier

Go with Asmoil Diff fluid and no friction modifier needed on LS diff.

amsoil recommends friction modifier

Joe I only use shaeffers oil in my truck so the amsoil wont work. The rep for my area is supposed to drop some off for me when he brings me my engine oil! Thanks for the advise though!
