I'm not entirely convinced it was an axle. It almost sounds like something broke in the diff based on what I saw of him inspecting the damage on a lift.
Block wise, the limits appear to be the electric arc wire spray coated cylinder walls. I've been monitoring the 3/4 series forums where B58 owners have been reporting scoring of the cylinder walls in 20-60K mileage stock and tuned B58s. The issues are compression loss, misfires, and power loss. The fix is a short block replacement. Since liners aren't used, you can't hone the bore. Hopefully it's only an issue with the earlier B58s. The Supra uses the same short block, different head though.
