Duncs,
I think you'll find that the 5-stud 'Cruisers have 14mm studs, hence the 154 ft/lb nut tension..
Roachie,
Off the top of my head, I'm pretty sure the recommended torque for the GU is 89 - 108 ft/lb .. even at the lower end of the scale, this is more than what is normally recommended for 12mm fasteners (80 ft/lb), and is one reason I've always felt that 12mm studs are 'barely adequate' for a vehicle of this size...
You only have to look at all the reports of lost wheels/ broken studs on GU's for confirmation of this.. My local friendly parts man tells me that they sell heaps of Patrol wheel studs, and replace heaps more in their workshop...
It is for this reason that I've replaced all the studs on both of my Patrols w/- ½" ones, 6mm longer than originals, & use correspondingly longer nuts to suit, which I torque to 90 ft/lb..
12mm to ½" may not seem like much of an increase, but (a) hold the 2 side by side, and the difference in cross-section is very noticeable (to say the least), and
(b) it is the largest one can go & still use the same wheels, and without making any other changes..
FWIW, I have one o' them there Shentai thingys... Handy gadget, but no way, no how does it go anywhere near my wheel studs.. Not ever, not even to loosen 'em.. In any case, by the time I've got the thing out, unravelled the lead, & pluggedit in, I will have 'cracked' the nuts w/- the cross-brace anyway ;-))
(YMMV)
