I replaced the ball joints on my 2006 F250 (passenger side) yesterday. I had ordered the parts from Amazon, and all were "supposed" to fit my truck. They sent National 710413 for the axle tube dust seals, which was NOT the correct part. I made a trip to town and spent the better part of an hour at O'Reilly trying to get the correct seal. They gave me National 710701...also NOT correct. Can someone, ANYONE, please provide the correct part number for these seals? It is amazing that something so known for failure is so hard to run down.

To be specific...I'm seeking the part number for those dust seals that everyone sees dangling on the front axles, where they've separated/come out of the axle housing tube.

Thanks!

The front inner on the axle should be a National 710492 and the outer on the hub assembly should be a National 710685. Straight from O'Reilly's web sight and took all of three minutes.

710492 is not the correct part for mine. Looked at one yesterday and compared to the old failed seal.

The original style axle tube dust seals have been superseded by a new design that is vastly superior to the old one. They look nothing alike. If its the right seal for your year and model truck per the catalog its the right seal and will work. I went through this same situation at NAPA some years back. FYI, this is the Ford part number if you need to cross it:

AC3Z-1S175-A
