I have destroyed 5 of the ones I am trying to get in and I really thing it is just the wrong size! Housing is a 79 ford f250 d44.

I looked in the timken catalog and they don't list it, what I am using is a 8660-S but only because it is the right size for the axle and looked close for the outside. I need to get the right seal so I can put my truck back together!

thanks..

If you still have the original seal, look closely at the inner rubber lip and get the # of of it. Normally seals cross over to different makes. A real good parts store with a knowlegable parts dude will be able to get you the right part. I have always had luck finding parts like this with BWS (Burt Williams ansd Sons) They deal mainly with heavy truck parts.(707)-427-1377. I can get parts at this place that NAPA can't! :skull:

thanks! The parts places carry timken and ya only showed one timken number so I'll check it out. Then I'll atleast try napa (autozone idiots are amazing..)

brandon your most likely going to need the national #2300 OR national 5131,they are your only 2 choices. if i was betting i would say you will need the less common 2300. the 8660s is a rear axle seal for a 1563 rear axle bearing :flipoff2:

I got a C-R 13164 in one side, it will work but I destroyed yet another putting it in the other side. I tell ya, I will be careful sliding those shafts in cause those seals are a BITCH!
