I have a 37 tube axle. Someone told me today it's a truck and not a car axle. That there was 2 different ones. He seams pretty knowledgeable about this stuff. Just curious if anyone can comferm this because I've never heard of there being 2 different ones.
In 1937 there were two car axles. one was a tube axle for 60 HP cars and the other was I beam used on cars and pickups. I don't know the specs on the large truck axles for that year.
Just wondering...Did they actually put V8 60s in trucks? Thats something I wouldn't want to be behind on a hill...
My former 37 pickup was a 60. By the time I got it, all that was left of the 60 stuff was the 4.44 rear axle...
There are two versions of V8-60 tube axles but they are so similar that most people would never spot the difference. And I’ve never heard of any of these tube axles on a truck.
Oh ok. I didn't know there was more than one. I have two and they both look just alike. This person said the ones I have are from a truck because they are I little taller profile than the car ones.
Those axles took a unique king pin and the k/p retainers are different too. The king pin has a radius machined in it and the retainer was a round cross section, not the typical wedge we are accustomed to seeing. If your axles have holes for the retainers smaller than 9/16” than they are unmodified, but if they are 9/16” somebody drilled the holes oversize to fit the wedge retainers and accompanying king pins.
Truck...in Fordspeak: Pickups and small deliveries were called commercials, and the entire chassis was essentially identical to the car chassis. Only differences were a few bolt holes and some extra spring leaves. Big trucks...totally different frame, axle is made for bigger diameter king pins, many parts look about the same as car but nothing is the same. This makes all discussions using the word "truck" about early Fords a problem...
If you are talking about the place where the bump stop bolts go. I have 2 axles one does have a little bigger hole than the other one.
Then I would expect the larger holes to be opened up to 9/16” for the wedge type k/p retainers, and the other axle is original as produced by Ford.
