I think someone (Beav?) said that it might be that you have over torqued your lug nuts... should be around 70-80 ftlbs.... 75 being a good number to set. I tried it, did some hard braking to heat up the rotors and they did true up..... The guys at cosco had the nuts at about 120ftlb...... I think they were afraid that I wouldn't check them after 20 miles.... I guess most of their customers don't and costco doesn't want a lawsuit for a wheel coming off
