Gasket on front axle CV shaft

Still wrestling with this bearing/hub replacement. I have the gasket that came with the new hub assembly and I've taken the old one out. They look pretty similar and by that I mean, the old one looks pretty intact, with the gasket more or less attached.


.
Looking at the axle, it looks like there is another gasket. Is this part of the old bearing gasket that just adhered to the shaft or is this a different gasket. And, if so, does this need replaced as part of this process or does the one the came with the hub assembly suffice?

.
It's looking pretty ragged. And, if it does come off, would it come off at A or B?

I took as screen shot of a new one and it looks like there is but I can't find it listed as a separate item.

 

It’s one piece.
It doesn’t come apart.

The other “part” or seal is in the back side of the spindle.

 

To clarify the above.
The whole thing “one piece” includes the metal shield too.

 

Ohhhh, so this is the same gasket, just looking at it from the other side. Duh!


So, then, this whole metal edge and all the old gasket material should come off? It should just be bare metal, correct?

 

The one in your hand looks like the inner hub seal.
It goes inside the spindle. It’s usually the one that comes with the hub.
Once the CV is removed, look at the back of the spindle. You should see it.

 

This might help

The 710573 seal installs on the inside of the spindle. The seal on the end of the CV shaft is separate.
I don’t have the part # handy but will post tomorrow. The inner 710573 seal is the one that typically goes first causing the bearing to dry and wear out.

 

TnShooter, thanks for the link, that was very helpful! So, it looks like what I have (that came with the hub assembly and the one I'm holding in the image) is hub seal (p/n 710573). It looks like I still need the CV dust seal (p/n 90304-A0001).

Ok, another trip to the parts store...

 

Yes that is correct. I do stock them if you can’t find them or they are on back order.

 

TnShooter, from the image in your other thread post, the "inner seal" would be the CV dust seal (p/n 90304-A0001) that I was asking about?

 

correct

 

Great, thanks so much! The different schematics (at least the ones I could find) seem to show it in a different (or at least confusing) position.

That seems like the hub seal (p/n 710573).

 

I’ve been doing this for decades, the A0001 is the seal on the end of the axle shaft, the 710-573 is the seal at the inside of the spindle.

 

It's best to buy the cv axle with that seal already on as they are a PITA to install if you don't have the right tool. I bought my axles from NAPA with them already on. The spindle seal was pretty easy to put in.

 

Unless you’re personally rebuilding your own axle shafts.

 

I believe you, I'm just confused by the schematic. Is it incorrect (which I'm not doubting), just trying to verify/understand what I'm trying to get.

 

I'm just replacing the hub assembly (and now probably the CV dust seal), I don't want to get into the whole CV axle.

 

The 710573 is pressed into the back of the spindle, the A00001 seal rides on the 710573 seal.
If you don’t want to touch the cv shaft itself, simple hub assembly swap then you don’t need the A00001 axle seal.

Make sense?

Looking into to the spindle cavity this is the 710573 seal in the back side of the spindle between the spindle and axle shaft.

Doesn’t get much easier than this.

 

sorry have to zoom in for the part #s but this should explain it quite well.

 

Really helpful, thank you! So the 710573 came with the hub assembly but it looks like I need the CV dust seal (90304-A0001). Is that something that is available third party or do you pretty much have to go with the dealer?
