Mmmm-hmmm. Lemme guess: you or someone else put on the lugnuts with an air wrench, right? Bad idea. Guaranteed to to strip the lugs. Also guaranteed to strip the oil pan, which is what happened to me back in '94. Spiffy-Lube had some Neanderthal teenager change my oil. Took the bolt off w/the air wrench and put it back w/the air wrench. Then, he tried to tell me that "um, like yeah maaaaa, the bolt was spinning like that before I took it off." Um, like yeah, maaaan, I'm gonna crack your head open with this here tire iron if you don't get the manager out here, like NOW! NE way, believe it or not, they only paid for half the repair because I couldn't PROVE that the nut wasn't stripped already.
NEway. Don't drive for extended periods, speed or corner quickly until you get that fixed. Good luck.
MichaelD or any other gearhead, might know the answer to this one. I was actually pondering starting a thread this morning.
Anyway, I know air wrenches are really can potentially kill your lugs if overtorqued. According to my brother, manually tightening wheels are the best because the centrifigal force of the wheels spinning will tighten the lugs properly. Any truth to this?
It's very unsafe in the long run, and can probably damage other parts of your car (eg. axle)... with only 3/4 nuts tight, u put additional stress on other components on your car, which may result in damages that are a lot more expensive to fix later...
