Hub/bearing info needed

Hello again everyone. Back to ask another question about hub/bearing.
Got the SKF assembly off rock auto which claimed to come with new seals. It did not. Will I need inner and outer or just the inner seal? Also can’t seem to find the O ring if anyone could point me to one on Amazon etc. thanks guys

 

The outer is a PITA to deal with.
Some guys swear you need to replace it.
I am not one of them. If the outer (on CV) looks good. Send it.

The inner is super easy. Might as replace it. The o-ring, should be replaced if you can. If you can’t, don’t sweat it. A super thin coat of RTV on the hub /o-ring is better than nothing. Honestly, you can probably reuse it and be just fine. But it’s so easy to replace, “you should”.
