#29, Ian there's no noticeable difference between the lateral movement of either shaft. I did notice that both shafts feel mildly easier to move towards each hub, and mildly firmer when moving towards the diff. Don't know if that tells us anything other than the spring pressures for each shaft are similar, therefore unlikely to be one broken? #30, here's another recording, this time made at standing height, and with the shafts in their normal operating positions. Sound a bit like a finger of metal is being put under tension and is twanging back into place.
