1985 extracab, slight leak from the pinion seal at the rear diff. Working from Rogers web page (thanks Roger) I have got it apart, now working on getting the old seal out, but that is a different story. I noticed the companion flange has a definite groove in it. Is there a speedi sleeve available for this application? Dont want to find out what the dealership wants for a new one, thats if they even have one in stock. Thanks guys.
