Post pics of the wheels at the lug hole and the lugnuts. Without the lugs installed.

Yep, then we'll school you on what's right and wrong with your wheels or lug nuts. Also what are you torquing them too? Please tell me that you are torqing them on and not just tightening them, steel wheels are easy enough to just tighten but aluminum is a much different animal.

That might be your problem right there. You only have a 7/16-18 stud and you are torquing to 120 ft-lbs. My 9/16-18 studs are supposed to be torqued to 130 ft-lbs with no lube.

By torqueing to 120ft-lbs you are yeilding the studs and they are breaking.


I will find a chart to show the proper torque based on stud size.

Here ya go. These values will vary depending on where you look but should all be within about 10 ft-lbs of each other.

I think these are all without lube so if you lube you should factor in the coefficient of friction for your lube of choice to determine your new torque value.

good lord ive almost been torquin them twice as much!!!

Yes you have. Like was already said, my 9/16 x 18 studs with aluminum wheels only torque to 115 lbs.

I think we've found the problem.
