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.

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

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

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.

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.

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.
