How often should you service a Dan's 44 rear end?

Both Avanti and '59-'63 Passenger Car Shop Manuals recommend checking level every 1000 miles. No mention is made of changing fluid. However, Truck Shop Manual of the same era recommends a fluid change and flush every 10,000 miles. Confused?

Current truck severe duty interval is 15,000 miles recommended by Dana/Spicer. Most light duty pushes it to 50,000 to 100,000 in modern vehicles.

I really don't know what to recommend as the vehicle and usage are not clear. But I would think five years and checking regularly would suffice.

Not sure what Dan recommends however, Sorry couldn't resist.;) Bob

If it is an unknown commodity, I would change it. After that, I would check it once per year (add as necessary). If it gets looking dirty or there is anything metallic about it, change it again.
These are strictly my recommendations, not from any official document.

Sorry about the spelling the phone did that one, I didn't notice till I posted. The previous owner of my 56j said that is what came in the car, is that the correct rear end for a 56j?

Yes. And you can edit any of your own posts by clicking on "edit post" at the bottom of your post.

this to me is a no-brainer.... really. You buy the vehicle and pull the cover. Drain completely and check gears via shop manual. Easy. Pull both rear hubs (correctly with puller). Inspect bearings & races, and replace as necessary. New seal inside and out..... and never touch it again..except pull cover for fluid

Yes, it is a Dana/Spicer Model 44, Tapered Axle Differential. The Ratio Tag should be under a Cover Bolt at about 8:00. Divide the Lower (Higher) Number by the Upper Number to get the Ratio.
