To find the code you will first need a fine wire brush. The you will have to located it on the housing. The best way to find it is to look between the 12 and 3 o'clock position (when standing outside the truck) and usually stamped in line with the welded on brake line clip, but towards the front of the truck.

The code will either be 3 capitial letters or 2 letters and a number. ALL rearends have this code, or did when the rearend was built. The only time I have not found this code is from a heavily rusted truck where the rearend was pitted.

I should note that there is also a 5-8 digit number there also, in the same line, but that is a production number and I can not do anything with that number.

Thats the axle code your asking for. The number on mine is KBY041W92.
