Ok so I removed the axle shafts from my ten bolts to have it sandblasted and forgot to mark the axle shafts and axle housing to match up when putting back together, my question is their an easy way to work out the right way presuming their is a wrong way, its a limited slip if that makes a difference

Left and right hand side are the same, but it is important to get used shafts back in the way they came out.
Check under magnification for wear on the drive side of the splines and, depending on their history, a slight twist in the spline. The twist is there for sure in the metal microstructure but may not be visible.
Putting them in "backwards" reverses the twist and accelerates failure.

Putting them in "backwards" reverses the twist and accelerates failure. That's what I am lead to believe as well but there was a mention years ago about the numbers or letter cast in the centre may have something to do with that, maybe it's just casting dates, but I remember people saying on one side the casting numbers ect was different to the other side. You should be able to see on the spline what way the pressure was put on it, I could see it on all my Banjo axels. People think that the shaft does not flex twist at all, but they sure do. But I think that the normal Holden axles are both cast in just the same way, but it is interesting to see how some axel shafts are bigger at the spline and then go a bit smaller and then taper out wider too the end and that some are staged thicker in 3 steps and that some do shot peen the shaft, the longer the shaft the more she will twist and I think that by staging it you are making the thin end shorter in a way and then the 2ed stage takes up less twist as does the 3rd part so as ending up with less twist, but does the outer part of the axel have the most strength and then shot peening this give it a how much more % strength. thinking like as in of a tail shaft how she is only due to the outer that gives so much strength. Crankshafts twist as well and some of them are not solid but hollow, same with camshafts, so the centre is not so important as one would think.
