I have a 3.55LS(H9) 9.75" with an axle tag#919B.
I can't find an axle or an aftermarket replacement. I am looking for a passenger side axle.

Can anyone help?

 

You can't swing a dead cat without hitting one. They are everywhere.

Googled "Ford 9.75 rear axle shaft" and cam up with several. Summit carries 5 different brands on their own.

I would think that the wreckers would have a bunch of them too if you are looking for used.

 

After spending over 8 hours researching and calling around I found the last new one in the USA. After national searches there are differences in the axle codes. The 919B is rare and Ford quit making them a few years ago and there is no more. Used there are currently 3 available in the entire country in wrecking yards that put parts in the system.

Most of the aftermarket like Alloy are not making a 919B code. I did find a couple making them in the $250 price range; with a 2 week build time.

Thanks for trying to help though grizztang

 

I must be missing something. To me as long as the 9.75 axle shaft is the correct length, the correct number of splines on one side and the correct bolt pattern on the other you would be good to go. What makes the tag #919B axles different from every other one out there? Curious as I too have a 2003 F150.
