Loose lug Nuts
Why the heck are the lug nutz on my drivers side aluminum rim coming loose all the time? All 4 rims are the same aluminum rim, none of the others are coming loose. Already had the tire come off once! Lucky I was only going 30. Ground the chit out of the caliper bracket, but nothing else was damaged. Now I have been checking the nuts every other day or so and I have to keep re-tightening them!!Profanity Removed!?!?! Any body got anything? I have heard of lug nuts on aluminum rims being HARDER to get off, but not the other way around. And it is only the drivers side. I am about to use locktite....

There is a special Lock-Tite or 3M that holds the nuts on, but is also made to allow you to remove the nut. We used to have some here at work and I looked for it to give you the name but I can't find any. I'll ask some guys around here if they remember the name. Unfortunately they've laid off all the machinists here cause I know they'd know.
One guy here wonders if you've got a vibration on that wheel that is causing it.

If it is only one tire, I might suspect an out of balance tire or bent rim. Maybe move the tire somewhere else and see what happens. Just an idea, something has to be causing a vibration.
Lock-Tite isn't a bad idea, but it doesn't solve your problem.
Just an idea.

I use impact on low setting to snug em (they are 2" long) and then t-bar to tighten. Prolly closer to 150 ft-lbs.

You don't want to overtighten them because that can break the stud on a bump. What you're doing is stretching that stud, and if it's stretched too far it can break when you hit a pothole or something. I believe the F-250 might be more than 100 ft-lbs, check the owners manual. But don't tighten them over 125-130, use a torque wrench. I agree with the others, put the wheel on the other side and see fi it does the same thing.

Are Your wheel studs to long for your lug nuts? My Ultra Wheels take a long nut to tighten down right.As Mustang wrote, be carefull not to over tighten your studs.Mine broke at 70 Mph. SAV

Rabid... I agree with 92's comment -check if the bolts are too long for the lugnuts, or that you've got a bad set of threads. You could swap just the wheel with a known good wheel as also suggested (don't swap the lugnuts) and see if the problem "travels" with the wheel. The idea is too change only one thing at a time.
After the swap if the "bad" wheel is Ok and the "good" wheel is not, for example, then you can narrow the probable cause ..

Sounds like you have a case of the Flat Rate Blues. Some overzealous Impact Wrench wieldin' supertech probably overtightened your lugnuts on that particular wheel and damaged the chamfer where the cone of the lug nut sits. Aluminum will "squish" under extreme pressure, and if he had one of those 850 ft lb. guns, well, that could be thought of as extreme pressure. However, if the wheel were allowed to become loose and wobble on the hub, then the bolt holes can be egged out, making the wheel move on the hub. This will make it virtually impossible to keep the lug nuts tight. Wheel replacement may be your only option.
