Not sure what it is. It came out when i was trying to put my cv axle back into its housing. I tried to look into the housing to see where it goes but I couldn't figure it out. My cv axle is back in place, but now I have the piece no idea what is it but it came out of the housing. Any ideas? Thanks!
 
Your right I just looked up the seal and it has that piece in it. It's the drivers side front. I should've done a better job looking into where it goes, thanks.
