I am in the middle of rebuilding the knuckles on my 74 FJ and removing old grease looking for surprises. When I cleaned the inside of hub I noticed a lot striations which makes me think that maybe it should be replaced. Since I have never done this before I am hoping I can get a second, third and fourth opinion. Can you take a look at the picture and let me know what you recommend. If the verdict is to replace then please let me know who I should reach out to. Thanks.
