4x4 front Axel shaft seals
 

Hello again to everyone @ F.T.E. I need seals both inner and outer on my 01 f350 wondering what you all are using . Fords outer seal is supposed to be an updated design, wile the SKF brand inner is about 2x the cost of Fords . Also anyone use National ? Ive always heard they are a good seal. and are reasonable on amazon . Its not all about price, I don't want to be doing this again any time soon ! Id pay more for the SKF inner if its that much better. The Ford inners don't seem to hold up that well. Any opinions will be greatly appreciated!
Thanks!

By inner and outer seal, I assume you mean the one that sits at the end of the axle tube (inner) and the one that sits in the hub (outer), correct?

If so, I'm putting in a Timken inner seal (710413, $17.99 at Autozone) and a Ford outer seal (f81Z-3254-CB). I believe that outer is available at Rock Auto for around 32 bucks.

Thanks for the reply , yes those are the seals and thanks for the part #'s Ive been trying to find out if theres some thing better than the ford seals . BTY I just jumpted to Amazon and ran the timken # and they said it did fit my truck. Its an 01 f350 4x4 .They have it for 14.25 +free shiping.

There appears to be a redesigned inner seal as well . Rock auto has a timken for $8.06 that they recomend, and another timken for $41.79 that they dont. (You know that little heart they put by a part that has high sales & low returns) the one for $41.79 apears to be the redesigned one. Now Im really confused!

I just finished up my truck, and here's a little advice if you use the Timken 710413 inner seal- DON'T initially seat it all the way on the inner shaft! Start out with the seal about 1/8 of an inch from being completely seated and trial fit the shaft, then adjust as necessary.

The reason I say this is because I seated my driver side seal all the way and it left a slight gap- a gap that was big enough not to be sealing anything. It was a pain in the butt to adjust back out. My passenger side seated all the way with a good seal though.
