Sadly it looks like Bubba bottomed out at some point in the 1980s on a joyride and smashed the sphere of the “end of the axle” where the steering knuckle bearing cup race lies ( is that the right term for the end of the axle tube? Ears? Atlas?) Anyway, the bearing cup was cracked and the crack raised a ridge in the casing. And, what’s worse, the bore for the bearing cup is deformed and the new race won’t press in easily. What should I do? Sand down the ridge? Heat up the whole thing and try to reshape it? Grind /tig /rebore? Is it even possible to source replacement D27A housings?
