Default Rear Diff Interchange

Hey All,
Before you flame, I know this is a common question. However, I couldnít find anything that explained it as to where I felt I understood the answer fully. Also, it seems thereís a lot of conflicting info out there.

Iíve got a 2002 Dodge 2500 5.9L Gas. Spicer 60 4.10. Itís got a bad diff and Iím trying to find out what years are interchangeable. I heard anywhere from 94-02 or just 01-02.

https://torqueking.com/category/1994...dentification/

That link above seems to indicate 94-02 for non light-duty as long as itís the 10.5Ē with proper gearing. What is light vs HD?

I live in Alaska where parts are few and far between. Just trying to make something work without wasting time or money.

Thanks in Advance.

Your truck is actually still a 2nd gen Ram. The D60 was used in all second gens, 2500 trucks with a gas V-8 engine. I think there are minor differences over the years, but, any of them should be a direct bolt-in. Unfortunately, 3.55 was the most common gear ratio, so, finding one that already has 4.10's in it, might be fun.......

The "light duty" 3/4 ton had a GVWR of 7500 pounds, (as opposed to 8800 for the 'regular' 2500. They were still eight lug axles, but, the were D44 up front, (on 4x4's,) and corporate 9.25 in the rear. You don't want axles from the light duty truck. I think they were 94-95 only.

Welcome to DF!

Awesome! Thanks.

I think Iíve tracked down a Dana 60 10 bolt from a Ford that should slide right in.

Thanks for the explanation!

The 2000 and up 2nd gen 2500s are a little differ in the brakes . Drum models had drums that slide right off, no messing with the axle. Yours probably have discs and that is even more rare. So front rear valving could be different and the parking brake might need to go with the donor.

I find more 410s than anything else in my area.... and here diesels usually hot the 354 while gasers got 410s....

I could readily put my hands on at least two pre 2000 D60s with 410a ...

Ah, yes, you bring up some VERY good points. I had forgotten about the disc brakes.

Also, the Ford rear may not have the correct provision for the rear wheel speed sensor, which the PCM also uses for the speedometer.

Ford also changed the lug pattern to 8 on 140mm?? Don't quote me but I found out the hard way when I got my father in laws 20" wheels and tires after he passed, I don't know the exact year they changed the pattern. I researched and found different answers some say it was the mid to late 90s, and some said it was the early 2000s.

The Ford lug pattern changed to 8x170mm with the introduction of the Superduty in 99, all 99+ SRW Superdutys have the 8x170 lug pattern.

That's it, lol. I couldn't remember if it was 140mm or 170mm, but I knew they went metric.
