Front Axle Identification

I have a 2003 F250 FX4 4X4. I read an article in 4Wheel and Offroad (1999 Ford F-350 Super Duty Build - 4Wheel & Off-Road Magazine) and during the build up they determined that they had a Dana 50 front axle. How do I know what I have? Are there any markings that would tell me? There is a tag on one of the axle tubes and it says that it has 3.73 gears, but is there anything else it can tell me?

I'm not sure on the tag but if you have ever had your axle shafts out you can tell easily. The Dana 50 shafts taper down to a "tiny" spline area where it splines into the diff. The 60 stays pretty much the same. I was disappointed to find out my 2000 F350 has the dana 50 when I was doing my ball joints....Unbelieveable! Good news is, if you ever break it you only have to buy a new axles from the ball joints in if you upgrade to a 60, just the carrier and center section are different if I am not mistaken.

you should be able to identify it from the tag right after the gears... mine said 3.73 10.5 for my rear...

Darn! I just missed it. This is one of the only doubts I have with my Ford truck. Why would ANYONE put a Dana 50 in the front of a F350 is beyond me!

I just keep hoping that it holds out and doesn't break too soon. :pray:

Thanks guys. I'll have to pull some more numbers off the tag. My front diff cover is starting to rust pretty good just like my oil pan. I was going to change to my diff covers to the procomp aluminum covers, or the mag-hytec.com covers.
