2005 F450 Rear Axle February 10, 2020, 03:17:20 pm I plan to change the rear end axle lube, but not sure about the the axle code? My chassis code indicates axle code 83. When I researched the code it indicates an Dana,E350, 4:30 ratio with non limited slip. Does any one know why the code is for an E350 chassis instead of a E450?2005 27 MB 1 Likes
Re: 2005 F450 Rear Axle Reply #1 – February 10, 2020, 03:45:42 pm Your 2005 should have a Dana D70-HD.It can be identified by viewing the differential cover, looking at its shape and how many bolts are used to secure the cover.This is what a D70-HD cover looks like.Differential Identification - Dana | RANDYS WorldwideChart showing photos of the various Dana axle differential covers.

Re: 2005 F450 Rear Axle Reply #2 – February 10, 2020, 06:57:41 pm Thank you Larry for the Dana web site. I used my Big Foot levelers in manual mood and was able to lift the rear end enough to Access the rear differential cover. Because of all the “stuff” I wasn’t able get the best picture of the entire cover. But the partial photo I did get(compared to the Dana Diff Covers) might match the Dana 80,’98 & newer Ford only-35 Soup line. I’m attaching a couple of photos with this reply.Thank again,Macmarty

For rigs that tow, a synthetic 75-140wt fluid may be preferable.Larry
Re: 2005 F450 Rear Axle Reply #5 – February 10, 2020, 11:11:03 pm Thanks Larry. The type of lube is really what I needed to know. On some of the previous trucks I’ve owned, an additive was needed to accompany the lube oil with a limited slip rear end. 2005 27 MB
