Various rear differentials

[dgrinnan]

I have a 47 WC 1/2 ton and I am fairly confident it has the original drive line.  I am going to pull the running gear out to replace the bearings and inspect the pinion to see if it needs replaced.   I was looking at DCM for gaskets for once I start reassembly.  They list 3 options.  10 bolt, 11 bolt and 12 bolt.  I have an 11 bolt.  Does anyone know if the rear axle configuration was an option or for the 47 WC was the 11 bolt the standard differential?

The 11 bolt is all you get in your 1/2 tonner.

8-1/4 ring& pinion...same as the six cylinder Plymouth, Dodge ,DeSoto and Chrysler std. wheel base cars.

Do you happen to know the ratio?

4.11 seems to have been the most common . Those that I have seen have all been stamped on the outside . usually on top but sometimes more conveniently down below .When looking , clean well and a mirror might help . Also can be stamped on the ring gear itself .

Thanks, I will inspect when I pull it out this weekend.

4.1 was standard with 3.73 and 4.78 optional for WC and WD-15(3/4T)
