Rear hub seal help

[sgtlyle]

Hello!
Was wondering if anyone on here has changed a rear wheel hub seal. See the problem I am having is getting the right one. I have went to 5 different part stores and they all have only one part number for my year truck. But the seal they have will not fit onto my spindle where it is supposed to ride when installed onto the hub? There is this rubber coated steel collar that is in the center of the seal that is holding it up. It moves but does not come out and is not supposed to. Has anyone else had this trouble? Im about to go to the dealership. 2000 F-250, Sterling 10.5 Rear axle.
Thanks in advance

I have one on hand from when i changed one side figured I'd do the other side on a rainy day.

Its a National Federal Mogul, Part Number 370247A

Dimensions are 2.955 X 3.875X.488

Hope this helps.

Thanks for the quick response. That is the same seal part number that the auto stores here have given me. It does not work. It is like my spindle is too big. Im going to have to get my Bill of material numbers off of my axle and take it to the dealership.

I've seen 2-piece wheel seals on the heavy duty trucks I work on. May want to look further into it, but I think the piece on the spindle has to come off before the new seal will go on.

You were both right. The seal was the right one. When I pulled off the hub the inner collar of the seal stayed on the spindle because it was so bad. It looked like part of the spindle. I feel like an idiot but live and learn I guess.
I put a new seal in from the dealership ($20 dollars cheaper than part stores and USA made might I add) put it all back together and it is dry as a bone. Thanks to the both of you!
