Again, thanks! | | | | Joined: Mar 2008 Posts: 6 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 6 | Hello, I have a 58 Chevy Apache 3600 with a Napco 4x4 installed. I have noticed that I have oil leaking out of the front steering knuckles. My question is where do I get the seals to replace the ones that are leaking. While I have it apart I would like to replace them all but do I get them from GM for the year and make or do I have to find them from somewhere else. Thank you for any help.

Good luck CR14866 If you can find them. found mine on Ebay National #480630 easy to find. Its a one way seal will let grease in but will keep oil out of axle tube . Make sure you have the knuckle greased right .
