Have another diff for you guys to check out. Just picked this up from a TGO member this morning.



Let me know what you guys think..



Thanks

 

It's a 10 bolt with an Eaton posi inside.

 

A 2 series one, with a "thick" ring gear.

 

So is it safe to assume that this will hold up to my V6 better than the previously killed Auburn at the strip?

 

That is NOT an Eaton Posi. That is a cone type differential, probably an Auburn.

 

^^ Looks like you're right, it's an Auburn. I found a pic on Jegs that confirms it..

Now to contact them and see what the stampings show it is..

 

Yup, it's an Auburn; a stock one, at that. 2 series. Pretty much, the dung.

What difference does it make "what it is"? That is, what would you do with that info, if you had it? I can tell you Auburn is among the least helpful companies there is, when it comes to maintaining their existing customer product base; more than likely they won't tell you anything you don't already know. Maybe there's some other way of finding out what you need to know?

 

What is the gear ratio?

 

4.10


sofakingdom, I had noticed that they have some 30 spline units and a few others on Jegs. I was hoping just to get total confirmation from them on the diff specs. 26 vs 28 spline, etc...

The numbers I have are partially covered up by the ring gear, the lady from Auburn was nice but said that i needed the rest of the numbers for her to help.

 

I would say that it's a 3 series if the gear is a 4.10. It doesn't look all that thick for a 4.10 gear. You can remove an axle very easily and see what the splins are.

 

30 splines would be for some other model of rear end... this model (7.5" / 7.625") only comes in 26 or 28 splines on the axles.

 

^ that makes sense.


I was hoping not to have to take it apart but i'm waiting on a new diff cover and LCA brackets so i do have some time. The axles in my broken rear are 26 spline and in good shape, would be nice to have a spare set.


Thanks guys, it'll be nice to drive my car again at least. lol

 

2 series vs 3 series...

Note how the 2 series ring gear flange is essentially flat on the side opposite the gear (because the flange is so close to the bearing), but the 3 series is more cone-shaped (to locate the flange closer to the center of the pinion).

Yours looks 2 series.

 

You are going to have to see a picture of the left side of the differential before you can tell if it's a 2 or 3 series. The picture doesn't show that side well enough to tell the difference.

 

Here is a pic from a little better angle..

 

Still looks like a 3 series to me.

 

crossing the part number on the ring gear shows it's for a 3 series.


Either way, still better than the old diff.
