    pinon seal leaking

    2004 tj front pinion seal is leaking. its a d30 and i know its suggested you get a new pinion nut but do i need anything other the a new seal. Also will National oil Seals Part Number 710461 be the correct seal?

    You can probably get by with just a new seal and a new nut, but I would question getting a new crush washer also.

    I have seen many crush washers that won't crush, so people reuse or the pre-crush the washer in a vise, therefore it should not be used. So your call on that. I would check to see if the bearings are good by trying to move the pinion up and down or side to side. There has to be a reason there is a leak.

    How many miles?
