Im looking for an axle shaft for a 55-59 Chevy 1/2 truck. Im looking for the shorter of the two. The rearend tech measured it as 30 inches form the outside of the axle flange to splines. The longer he said was 31 inches. Mine seems to have pitting where the axle bearing sits, so they said it needs to be replaced
They make a sleeve to repair those areas. I'm building a NAPCO and found sleeves for my front axles as those axles aren't easy to find. I think I found it on Rock Auto but I'm sure many others carry them.
Don't pay no mind to that whirrin' sound, she uses a little oil but outsida' that she's cherry.
