Eaton ho72
I picked this up today. Has 4:10 gears and I think a no spin. I can’t see a center pin, all 4 holes on the carrier have something in them if that makes sense. How can I tell for sure?

Re: Eaton ho72
Looks like a open diff
.No spins don't have the spider gear that is shown in your photo. Should have numbers on ring gear to tell gear ratio and date code. They don't use center pin but a cross set up on both open and no spin |

Re: Eaton ho72
Yes the center section it should bolt right in. However the gear ratio does not match the front so you will have issues there. So either regear the front or replace the carrier with the new axle to fix yours keeping your 4.57. Or never shift out of 2wd.

Re: Eaton ho72
I can't answer your question but I have 2 links saved
that are an interesting read. 1st one has info about spider gears. 2nd one has good pictures to show what the Eaton looks like torn apart. Link 1: http://67-72chevytrucks.com/vboard/s...ding+HO52+HO72 Link 2: http://67-72chevytrucks.com/vboard/s...d.php?t=536119 Hope this helps and in no way am I try to make this about a 14 bolt swap subject. I want to run my Eaton also. I have 3 center chunks. One of them is an early Eaton that have one pinion bearing an a bushing in the rear of the pinion. The other 2 have pinion bearings in front and the rear. .

Re: Eaton ho72
I know about the ratio mismatch. I’m trying to isolate some noises so I was just going to swap those chunks for a test and not use 4wd. Thanks
