Front axles: Dana 50 vs 60

You guy's want to talk Dana 50's vs Dana 60's?

Not a whole lot out there, but some good info none the less.
I'd like to learn more about what 50 parts transfer to a 60, and what parts don't. Lets stay away from the Unibearing 1999 and up stuff for now.

Good point, and I should've expected that.

But why?

Isn't the only pre-'99 Dana 50 the TTB version?

In that case, the only thing that transfers is the spindle, bearings, wheel hub, rotor, and hub lock.

Yes, 1980 to 97 (The solid axle 50 started in 98.5, I think the last year was 97 for the TTB, I'll have to check)
Edit: I was wrong, 98 was the last year for the TTB 50. BOM 610740



As for the Transfers: Your not 100% correct, now prove I'm wrong. What about the Caliper?

Dana 50's use dana 44 ring and pinions(8.5") and dana 60 outers. I prefer the larger gears(9.75").

This is more of a general assumption, however it's incorrect.

Can you give me just ONE part number that transfers form a Dana 44 to a Dana 50?

I'll make it easy, here is a picture


Edit, 73 and cotter pins don't count.

I just want a end all be all thread that shows the differences between a Dana 50 and 60.

I'm trying to find that one out.
I read a post here that said they were not...


Spindle bearings are the same, all three.

Someone has to guess...

Which one is the Dana 50 and which hub is the Dana 60?
Hint, one is an 1988 the other a 1990.

Example of the Dana 50 TTB & Dana 60 (pre 1999)parts that interchange.

Spindle needle bearing Oil Seal -> 620062
Spindle needle bearing -> 620063
Spindle & Knuckle locknut -> 36805
Back of hub oil seal -> 48816 (note: early to mid Dana 50's are 37729)
Kit inner wheek bearing (hub) -> 706411X
Kit outer wheek bearing (hub) --> 706074X
Thrustwasher wheel bearing --> 33734 (Both Dana 50 & 60 some models don't list a part number)
Spindle Nut -> 660568 or 33732 (Both Dana 50 & 60 models very between these two part numbers)
Lock washer -> 620128 or 33733 (Both Dana 50 & 60 models very between these two part numbers)
Spindle nut outer ->621027 or 33732 (Both Dana 50 & 60 models very between these two part numbers)

Why did I cut off the bottom? To keep you guessing


Spindles. I sure can't find the difference I read about...

So then, why all the hype about 60s? Surely there must something.

R&P diameter? Tube Thickness? Divisibility by 3? What?

didn't all the 50's have a metric bolt pattern?

50 has:

8.5" ring gear, 26 spline pinion, 30 spline axles, 10 ring gear bolts

60 has:

9.75" ring gear, 29 spline pinion, 35 spline axles, 12 ring gear bolts

SO even if the outers are interchangable (which from what I've heard, they are) your center chunk is still pretty much a 44. It's definitely a beefy axle... but it's no 60. It can't be converted to 60 if that is what you're getting at.

oh and yeas, you can run dana 60 outers on a 44 TTB using 50 parts. No clue why anyone would do that but I've seen it done

First and foremost the TTB 50 is an independent axle, a thus has a third u-joint in the center of the axle. It's not good for trailriding or rock crawling.
The 60 is a solid axle, much better

50 has smaller u-joints and axle shafts. They are better than a Dana 44, but see the above, I'd rather run a Dana 44 solid axle. (I did try to fit a Dana 50 u-joint into a Dana 44 housing, can't be done with out chaining inner "C's"

SO the 60's really are a much better axle. However there is a thread on here where a guy took a Dana 50 and make it into a poormans Dana 60.

I think that split was in 1998.5 any Dana 50 axle built after mid year 1998 should be a solid axle and not TTB. Those axles are the ones with the metric bolt pattern, and a Unibearing.

With Pictures!

the 50 is definitely a poor mans dana 60... but then again so is the 8 lug dana 44... and they are WAY cheaper / easier to come across

D 50 hub is on top. The three lockout retaining bolts give that away as opposed to the 60's 6
