Axle seal orientation



I've got the 2 little guys in my head arguing right now on which way is the proper way to go, so figure I'd come here for advice.

The old seal came out with the flat side in, indented side facing out, as can be seen in the top pic. If I follow this same logic to install it, it makes sense that the flat edge should rest against the lip in the axle housing. On the other hand, logic also tells me that the side of the seal with the spring is the side that faces the oil, which would be the opposite installation, with indention facing inwards, which doesn't make sense with the lip in the housing.

What's the right way to go?

Spring on oil side; flat face to the outside

Sounds good, that made the most sense to me, especially with the taper on the seal, but just wanted to double check.

I wonder if the old one was installed backwards which is why it was leaking? Or maybe its just a different design all together, and just the seal went bad.

Sort of related to this post, but as mentioned in my pinion seal post, here's a pic of the axle gaskets that I've been getting. When fully pressed on the studs, I have alot of excess gasket (like manufacturing specs are wrong). It seems like they're serving no benefit to me and get creased when installing the axle.

Possibly, if you punch out the holes for the studs a little bit, it will allow the seal to lay flat. It looks too tight, binding on the studs.

I was gonna do that before putting it back together. I've bought these gaskets from 2 different vendors so far and both times they were like this.

Somehow that doesn't look like the right gasket. I usually just make my own out of a brown paper bag or some craft paper.

Love the bag idea. I think I may just do that.

Unfortunately for us that are still wrenching on these old piles of iron, many suppliers have/are trying to pass off service parts that 'are kinda close' as the real mccoy...... even though they are in a box/bag marked with the correct part number, the part is not the same when placed side by side to the OE. Beware, my Friend, beware.....
