For this reason I inspect the axle shaft key slots very carefully during a differential overhaul.

Eventually the crack will increase until it travels the full circumference of the shaft, and then separate.

Tom, how do you rate the new axles that are available? Are the axles sold by the various suppliers all from the same source? If no, which ones do you recommend?
