I recently bought 4 of the FJ Aluminum wheels on CL.
Seller was a squared away guy and he gave me the correct (washer style) lug nuts.
I had the tires remounted on the FJ wheels, and 100 miles later I re torqued the lug nuts to 83 f/lb (with a borrowed wrench). All were maybe 1/8 turn loose at that time.
No big deal, I figured that was it.
I've been checking them once a week for the past month and every time, at least 4 of the 6 nuts on each wheel are loose, always about the same 1/8 to 1/4 of a turn. This is after only about 200 - 500 miles each time.
The lugs are the correct length (I can get a nut 10 full turns before it begins to tighten against the wheel) and the nuts are correct for the wheels (I think, from the research I did). There is no damage to the wheels that I can see and no excessive dirt or corrosion that would impair the ability of the wheels to correctly seat.
Is this normal for these style wheels, or is this a problem? I've never had steel wheels loosen except maybe the first time, after that, the lug nuts never budge. It's getting annoying and I wonder how they will hold up when I go out west this coming year, thousands of miles.
