I need an axle id the axle is in a 03 250 7.3. The axle tag reads

3 V 423 C
L73 10 5 2G31

 

THE 3l73 IS 3.73 GEARS AND A LIMITED SLIP
THE 10 5 IS THE SIZE OF THE RING GEAR 10.5"
CAN'T HELP WITH THE REST.

 

05 super covered the important parts. The 3V423C is the plant code and 2G31 is the date code of where and when it was built.

 

So is this a Dana 60 or is it something else?

 

No, it's the Ford 10.5" axle not the Dana 80 or 135

 

Yea I somehow managed to get two posts going on this ne ways i have a leaky pinion seal and I am stuck on the repair i do not know how pull the wheel that the yoke bolts too is there a special tool ne hwlp would be appreciated

 

Is this what you're looking for?

 

This is the job but I have a different set up in mine there is a circular plate coming out with the pinion in the middle if i can remove the platei could get to the seal i definitely did not plan on pulling the pinion although it seems unavoidable i thought this would be a simple fix ie. remove drive shaft pull plate out replace seal otherwise i dont have required tools

 

ok I see what is going on I will get tools required and try to finish tonight update tomm hopefully

 

The procedures posted by F350-6 are the correct procedures. You will need to pull the yoke to do this. It is also of the utmost importance that you take that pre-removal preload measurement. Failure to do this can result in messing up your rear end leaving you stuck on the side of the highway.

 

What is the pre removal preload measurements?

 

has anyone else done this? is it neccesary to remove brake calipers? also I removed pinion nut prior to receiving these instruction can anyone give me the torque specs if i do not need to remove calipers i could get puller and pull flange and replace seal tonight but i do need the tq specs if anyone could help i hope I havent screwed up too bad

 

There isn't a torque spec on the nut....it uses a crush collar.
I'm not sure what the rec. spec is off the top of my head for the rolling resistance.

 

What is rec spec? and how do I find out how much to tighten as well as do i need a new pinion nut Im pretty sure that i do

 

However you do this, do it the same every time.
Place the rear of the vehicle on jackstands. If the tires are on for this measurement, make sure they are on for the reinstall measurement. If you pull the tires, then make sure the tires are off for the reinstall. Same principle with the calipers.

Next, using a torque wrench that measures in inch pounds, measure the force needed to rotate the rear end when you turn it via the nut in the middle of the yoke. Record this measurement and then during reinstallation you torque the pinion nut until you achieve this same amount of rolling resistance. This ensures the bearing preload is identical to what it was when you took everything apart.

The way I was taught, pull everything, wheels and calipers, then measure the rotational resistance before you pull it apart(IT being the pinion nut that holds the yoke on); however, different guys do it differently and you should be ok if you leave everything on, just so you do it the same every time.
