I would also suggest - if you are using MAINLY modern type cars - look at Tyre Razor as you can do both rears or fronts at the same time. (but not a cheap unit)

I have the Tyre Razor and it is a dream to use, truing both tyres at the same time. Both 1:32 and 1:24 work flawlessly, no shaft issues, no break downs, nothing.

Which is why I find the issue with the shaft on the Hudy, here I was thinking that the Hudy was a better machine but it doesn't seem to be. Glad I have my Tyre Razor now.
