ESOF problem

I have a 03 6 liter and the ESOF does not work. The previous owner said he always manually locked the hubs. I diagnosed the problem to the drivers front hub. It will not hold vaccum, the other side does hold vaccum. I replaced the front O ring and the drivers side still will not hold vaccum. I assume there is a rear O ring, but I have no idea of how to access this seal.

Can anyone point me in the right direction to fix my ESOF Please. I found nothing on youtube for the rear seal....unless I need a new hub or there is something I"m not informed about regarding the hubs and/or ESOF.

Thank you!

JB

Thank you for the detailed infromation!

Um, after reading that, I think I will just leave them as they are and adjust them by hand when needed

Unless there is an underlying problem with my truck in that area...my ball joints are in perfect condition so maybe I can just get a seal kit?
