If you mean the rolling diaphram seal, off the top of my head its a Motorcraft BRS-84.

Dave, I am talking about the seal that goes in the back side of the hub and seals the hub to the spindle. What is a rolling diaphram seal? I am kind of guessing that might be the one that seals the stub axle to the back side of the spindle but?????? I suppose I should actually replace all the seals when I pull it apart to do rotors and calipers.

I have the factory books which I really like. I have had it apart before to repack. I just want to order all the parts and have them on hand when I dig into it.

It is the number of the axle-back of spindle seal (RDS). I can seem to find it only at the Ford dealer. The rotor seals I've been able to get anywhere so I never wrote it down. The rolling diaphram seal does not need to be replaced when repacking the bearings.

Tom how about F81Z.1S175.HCA SPINDLE SEAL INNER AND F3TZ.1S175.AA SPINDLE SEAL OUTER HUB SEAL IS F4TZ.1S190.A :pullover:

The hub seal part number does not want to work at online parts places for some reason.

Tom I think it is a F7TZ.1S175.AA instead Kip Also I think the outer spindle seal is F2TZ.1S175.CA for auto hubs and F3TZ.1S175.AA for manual hubs and the inner seal is the same on both F81Z.1S175.HCA I hope this helps

I have done some more research on this one and went to a medium duty truck parts place http://www.drivetrainindustries.com/ that was helpful when I needed the spindle nuts to convert to manual hubs. The counter guy was formerly of a local 4x4 shop so he knew most of the part numbers off the top of his head. I have since verified them on the Dana site. The prices were also really good compared to Ford. The spicer part numbers are as follows for my front axle which is bill of materials number 610609-2
708084 SPINDLE SEAL & BRG KIT this is the inner and outer spindle seal, the spindle bearing, and the spacer. $12.51
48816 HUB GREASE SEAL $3.49
The Dana/Spicer Catalog is available here http://www2.dana.com/pdf/X510-9.PDF The Dana 50 information for the F-250 starts on page 137 and the Dana 60 information for the F-350 starts on page 159.
To use the catalog you will need to have your bill of material number off the decal on the axle. The catalog has nice exploded parts drawings and documents every part number from ball joints to pinion bearings. I saved a copy on the computer and printed up paper copies of my applications.
Since it comes up from time to time the correct spindle nuts to convert from auto to manual hubs are as follows:
660569 nut and pin assembly
621027 spindle nut.
