OK, my ESOF is starting to get slow. Checked vaccuum hoses and connectors and they are OK. So, I am going to replace the seals and O rings, and repack and lube the front end.

Does anyone have a list of part #s and an online source?

Any helpful tips before I jump in?

Thanks in advance,

I've got the manual hubs. As I recall there are two O-rings on them:
One O-ring for sealing the lock/unlock dial and another O-ring for
keeping the crud out of the hub's bearings and splines. Anybody know
the Ford and industry part numbers for these O-rings?

Tnx, --Old_Dog

Thanks for the #s

BTW I think the wheel bearings are sealed.
