I'm getting ready to buy a front axle assembly for my truck and the parts search is asking me if the thickness of the hub flange is 10mm or 13mm. I have had no luck so far in figuring this out. I know my gear ratio is 3.73. It 99 F350 crew cab long box, 7.3L auto tranny. This is a late model 99 and I'm guessing that is where the difference in the hub flange thickness is. If there is any other info that is needed to figure this out I can get it pretty quick. Anyway, if anyone happens to know this tasty tidbit of trivia I would be forever grateful for the info so I can finally ge my damn 4 wheel drive working again. Thanks for the help

is it an early or late 99,what is the production date?

 

It's a late 99

 

Mark,


Pretty certain your 13 mm.


Are you renewing the axle/just hubs....what's up.


BTW there are 13mm hubs on ebay from Detroit axle for 58 a piece. Smokin deal for a well known name with a great rep.

I am replacing the entire axle assembly. Mine is trashed from the previous owner. I wouldn't care about the flange size but I have brand new brakes (as in everything) as well as some other new parts on the front hat I am going to use on to new one. I was guessing 13mm so that's what I am gonna go with. Thanks for the input.
