FYI guys, the Hollander interchange manual shows the 54 2 ton as having the same hubs as the heavy duty version of the 55-59 1 1/2 ton with a heavy duty front axle. The medium duty front axle for 55-59 is not the same as the 54 2 ton.
46-53 2 ton front hubs are the same as 51-52 1 1/2 ton and 53 1 1/2 ton with a heavy duty axle
