| Rear Huh Axle Seal? (Page 1/2) |

Help me figure this out.
Tonight I went to replace the driver's side rear wheel hub.
Prior to this, I'd had a knuckle from another Fiero that I sandblasted and painted. I had an axle from that Fiero that I used to figure out in which direction the seal should be oriented. With that axle, the seal mates up perfectly in one direction, and wouldn't allow much to enter the hub assembly.
When I went to bolt it in, I found that the seal that was on the old knuckle was the opposite of how I'd installed it in the one I cleaned up. The axle has this...thing...on the end, which also appears to be some kind of seal (it's not on the other one) that mates up with the seal in the hub.
The "thing" is hot rusted garbage, and I'm not sure what it is, or if it's replaceable.
Should have taken photos, but I ran out of both light and time. I put everything back in place since I don't currently have a place to store parts in a good manner (apartment parking lot).
Any idea what I'm talking about?

Some have found that some of the replacement axles have an ABS reluctor ring on them and they can cause interference, preventing proper installation. The stock axle has a flange made onto the CV joint that inserts into the hub seal. The hub seal open side goes toward the CV joint. It should have some bearing grease put into it at the time of installation. That 'ring' on the axle rides inside the rubber seal. If the seal is installed too deeply into the hub, the ring can cut through the metal housing of the seal, so it's important to make note of how deep the old seal was seated.

These are the axles that came with the car, as near as I can tell original to the car.
The flange you're talking about, OTOH, is the thing I'm talking about. Where can I get a replacement? The one is rusted garbage, and will destroy the new seal if it stays. Can it be replaced? Or, better to remove it if it's not replaceable?

There should be a metal guard on the outer CV that is just lightly pressed into place. This piece may need to be transferred to replacement axles. That guard protects the hub seal from dirt and so on. Try not to mangle it when you move it. It is better to work it off with a bunch of light tapping than try to get it off in a couple shots.

From your site. I /think/ this is the thing I'm describing. The one on mine is a rusted mess

I found an image on the site which describes what I'm talking about ! It's a "seal protector". Where do I get a new one, and how to remove the old one? CAN they be replaced ?

I think what you meant to say was, "if the seal isn't installed deep enough" because the ring nests into the seal, is that accurate?
The link I posted just above this is the transmission seal. The ring is rusted and falling apart, can I replace the ring, or can I just remove it?

That is a seal that goes into the transmission. The hub seal has the rubber seal on the inside of the outer perimeter. It's larger in diameter than the one that goes into the transmission. There is a ring flange on the hub end of the axle that rides inside the hub seal. If the seal is installed too deeply into the hub, it will be scrubbed by the axle flange. If it's not deep enough, it will not effectively seal. That's why it's important to take a depth measurement from the outer surface of the hub to the metal housing of the seal before it's removed.
In the image you posted of the axles, where it's indicated "Seal Protector" the next step down to the left is the flange that fits inside the seal. The seal protector rides near the face and acts as a slinger, keeping most dirt and water away from the seal, while the flange actually makes the seal.
Look at my thread and make yourself one of The Ogre's seal installation tools. It's invaluable for installing the hub seal.
Since you're reusing your old axle, you would be best advised to replace the axle nut with a new one.[This message has been edited by fierofool (edited 04-26-2021).]

Okay, wow, I guess I wasn't clear. I already reinstalled the hub seal. My question is about the seal protector. It's rusted garbage on my axle. I need to know if it can be replaced, and if so, where do I get one? Or, can I just remove it? It will very quickly destroy the new hub seal if I use it as-is. Or, perhaps that IS the flange? I don't know. I do know it'll destroy the new hub seal.
also: the new hub came with a new axle nut. Haven't yet put it on, and won't until I figure out what's what.[This message has been edited by ArthurPeale (edited 04-26-2021).]
