Yeah, that's it essentially.
Finally managed to get through to MSF Racing Components.
They don't specify torque values as it's dependent on the thread size of the hub spindle, plus strength & size of the hub nut. . . which makes sense really. So 'full tight' would be different for every application.
For a 3/4 inch spindle thread & a thick high tensile nut, around 100 lb ft or so was mentioned though.
I'll go with what John said I think as my spindle threads are closer to 5/8 or 11/16.
Thanks for the input guys, much appreciated.
Cheers, Jason.
