I've searched this topic and ended up back with the workshop manual.   44 to 55 lb ft for wheel studs and nuts.   However 65 lb ft for hub extension studs.   Its the same studs... why the difference?   My wheels are alloys if it makes any difference and I torqued them to 55 lb feet which doesn't feel particularly tight. I also tried 65lb ft which feels better.   What's the consensus here guys?   Cheers   Darren
