Pinion seal number or alternative info.

[Ron Dame]

Like all, I miss the old FLAPS who had the old guys that knew stuff, or had catalogs and not computers.

I need a pinion seal for my 1980 Avanti II, and you all know the drill. Who made it? Is it a Ford? blah blah.

I'm not sure if any year DANA 44 pinion seal  is the same or not, so don't know whether to try to ask for a 1980 Jeep, a 1963 Studebaker, or something else. A part number would be nice as well, as I don't want to pull this one out until I have a new one in hand.

Thanks!

A ‘National’ #5778 will do the trick!

Oreillys auto parts sells the seal.  It’s a Dana 44 and the part is shown under 1980 Avanti II in their software.  You might as well get a cover gasket and do a full fluid change while you are there

If you need a diff cover gasket, an RDS # 6629 will do the trick!

I'm wondering if I should change the bearing while I'm there? Is it pretty straight forward, or would I need to re-shim?

You’ll need a press and bearing adapters to change out the 4 bearings, plus a new crush sleeve. It’s not an easy task to do, especially knocking the pinion bearing races out and back in the housing. If the new bearings are too much different from the old, then you’ll more likely than not, introduce ring/pinion howl.  
 

If the you don’t have any noise now, then I’d change the seal, gasket and lube.
