Would the axle shafts from a 47-50 1/2 ton pickup work in a 51-54 pickup? I think I read somewhere that the differentials were different in some manner but I am seeking to make sure of that before I buy anything.
Thanks in advance

However, they are all the same length and have the same number of splines. Go back a page in the book and find a different length 47-50 1/2 ton rear axle? Maybe someone knows the answer. Are there stamped numbers on your axle? | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | When Chev went to Bendix brakes in 1951 they reduced the brake drum pilot size on the end of the axle.
1951-61 axles all interchange.

Dave,
Why were there 2 sizes/parts for 47-50 1/2 tons?
| | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | There are left and right axles, and they are different lengths.
Is that what you are asking Tim?
Maybe in my earlier post I should have said 1951-61 axles all interchange on there matching side.

I have an opportunity to acquire 2 NOS axles, R & L. If there not too large perhaps they could be machined down.

Walt Huck pilot diameter: 3.875" Bendix 3.550" I am sure the lugs would hold the drum close but they are held perfect by the center pilot.

Thanks
