Help me Identify this part CV axle Part

[txcaleb]

I recently changed out my CV axles with CVJ remanufactured axles recently with a buddy. Neither of us are experts, so we did a lot of research on the process and how best to avoid jacking things up. Honestly we thought it went pretty swimmingly, but when I went to take my axles back to CVJ I found this part laying near my drivers side cv axle assembly. That Axle turned out to not be an OEM axle unfortunately, so maybe this is something OEM assemblies do not have. My initial thought was that we somehow pulled the seal out with the axle, so I ordered part 90311-47027 assuming that was what I was looking at. Nope. Went ahead and bought the other side 90311-47013 in case there was a mixup on which side the mystery seal came from. Still not it. Since I thought I didn't have a seal, I have been monitoring my front diff fluid pretty carefully and have not noticed any significant signs of leaks. I think I can feel something "off" when I am driving, but I might just be paranoid.

Also a bonus for all you replacing your differential side seals.

Thanks for the replies, I can tell where it's missing I think. Last thing between the CV axle and the wheel side of things?

Yes, it's the wheel bearing seal.

It's the Knuckle/Hub Seal.

The factory axle has it's own similar seal, the idea being the two will squish together when the axle is installed in the hub and protect the back of the bearing from moisture/dust/debris.
