Yeah, that is far too tight, it's a wonder it hadn't damaged the wheels let alone the nuts.I did them back up to, a squidge over 100ftlb.. book says 103 but wrench only goes up to 100.. close enough.. i can do that result with the wrench which is less than half the length of my breaker bar. 140nm i think.
Don't know but gut says ~500lbft.. that's getting on for 680nm
