My 47 Ford 1-ton stake bed has this axle installed. I don't believe it is the original. It does not have a tag. Can anyone identify it? Thanks in advance for any help. Roy

It is a later model axle, probably a Ford unit. Most one ton trucks those years had a two piece "clam sh*ll" housing, while the lighter trucks used at "banjo" axle with an open driveshaft. It was customary to replace a bad axle with a junkyard unit because the clam sh*ll type was a very difficult axle to repair and adjust.

The original axle, as the man said, would have been a split case Timken Model 51524. The main reason these trucks end up with different rear ends is to make them more able to keep up with modern road speeds. A common replacement axle is a Ford 9" if the owner wants the 5 lug x 5.5" pattern, or a Dana 60 to use the 8 lug x 6.5" pattern. No other manufacturer used the 5 lug x 6 7/8" pattern that originally came on the tonners. Stu

You can pin this down as a Dana, as the two cast-in pockets on either side of the rear cover are only used on Dana axles. These are used with a set-up spreader fixture when pre-loading the differential side bearings.
