I'm sure it was spinning when it landed and the tire just stopped and the driver was stuck too. The axle is fine i'm sure. $30 at PAP will get you another knuckle/spindle/caliper bracket, if it needs it. I know there are two waggys in lithonia. The shafts and ujoint are another story but sounds like the warranty should take care of it. As long as the inner C ball joint mount is fine she should be good.
well, forgot it was a flat top knuckle, so never mind. However the spindle and bracket are the same and wouldn't hurt to have a spare if you keep the 44 for a while. However I'm willing to bet the knuckle is useable with just some new studs. Not sure what all the little half circles are from though?
I also MIGHT have a flat top around. However after two moves I don't recall seeing it. I did have some at one point that I didn't use. Not machined though. Was going to but the jig I made was wrong.
