O.K., I got my axle off last weekend. There were three dimples in the back of the differential housing, as in this picture. Do these serve a purpose? The two outer ones look like they are supposed to be there. The one, off center, in the middle, looks like someone backed into something. But now that I see this picture from palmaceae (sorry, I stole you picture), I believe it was intended to be there.

I pounded the middle one out, nice and smooth. Now, please, someone tell me I should not have done that! ::

You straightened out the gear fluid vortex flow dimple! You won't get twenty miles out of that rear end! Just kidding!

Uh, it's supposed to be there. At least it is on my coupe.

Yes, I am getting that. I suppose I will go out and re-dent the housing. Anyone know what the purpose of it is???

What? You don't believe the gear fluid vortex flow dimple explanation?
Probably just a stamping/press alignment thing, no big deal. Of course it could change fluid capacity by a couple cc's. I wouldn't bother to re-install unless you're going concours.

Just my guess but I think they provide support to the main bearings in the carrier.

I dunno why you wouldn't reinstall dents :: That's my favorite part, especially when I'm using a BFH. :joker:

Every time you bend that metal it gets substantial weaker. I would leave it the way it is. If it actually is a support for something the chances of you getting it exactly "right" are about zero. So it is either going to work like it is, or you'll need to get another part.

That's where the fill plug is on my '66. My guess is that plate is made with the dimple and was drilled and tapped for the plug When the fill plug moved to the gear unit itself, they just left the dimple.

Ford designed the original housing by using Kirk Douglas's chin as the prototype. :lol:
