Default Wheel fell off

This past fall I was taking my 80 out for the final drive of the season (I live in upstate NY - Rochester) and the left rear wheel came off. I had been out driving for about 15 minutes and was doing 30 miles an hour.

The car suddenly felt as if I was driving over the slotted road markers on the right side of the road, then the wheel came off.

I had the wheels off in the spring and had driven about 250 miles all summer.

The lugnuts flew off, but did not break any bolts nor do any real damage that I can see.

As you can imagine, I am very unsure of myself at this point and am hesitant to take the car out. Is there anything I can apply that would help to prevent this in the future? Is there any advice anyone has to offer that may help.

I typically work on the car myself, however, I am hoping to find a good Tech in the area that would be willing to put it on a lift and inspect the whole car underneath for damage prior to the season.

Any help is greatly appreciated.

I make a habit of torquing the lug nuts down just before I put the center cap on. That way, there is a visual reminder there, if the center cap is off, the nuts haven't been torqued. Center cap on=torqued nuts.

Could you have forgotten to double check the torque on the lug nuts last time you worked on it? (Don't ask why I thought of that first )

No - I definitely torqued everything down. That's what scared me about driving it going forward.

There can only be 2 reasons why your wheel came off. 1, you didn't tighten them down good enough and they came loose in 250 miles. 2. somebody doesn't like you and loosened them up for ya.

Every time you have the wheels off you are suppose to recheck the lug nuts after about 100 miles to see if they have loosened up at all. Most of the time they won't move, occasionally they one will need a slight adjustment.

Was the wheel on straight before you torqued it? I once had a problem on my truck where I didn't get the wheel all the way on to the hub before tightening the lug nuts. Once on the ground and rolling the wheel seated itself and the lugnuts were loose as can be. Luckily my buddy spotted it before I got too far.

I'm pretty sure the wheel was on properly. I suppose it's possible to gain access to the car, but it's in a locked garage, so I doubt that is what happened. I failed to check them since putting the wheel back on in the spring. I will be sure to check them more often.

That happened to the guy that owned my 81 before me ...except it was the front L. wheel. It took out the L/F fender and ground down the A-Arm and rotor shield. Goofed up the bottom of the front bumper too (that's why I got a decent deal). So, you got lucky if you don't have much damage.

How the heil do all the lug nuts unscrew themselves, sounds almost impossible to me. I have heard of someone driving with no lug nuts on at all, the wheel was stuck to the rotor, he made it home without the wheel falling off

Never had a wheel come off either but. Odd question, but do you have the correct wheel nuts for the wheels, seen that happen once.

What did you torque them to? As I recall from the aluminum wheels on my 02 they are supposed to be 100 foot pounds.

This is the right answer, simple and sweet, aluminum wheels are notorious for this,, ask any tire shop,, they must be torqued correctly.

I've known two people personally that have lost wheels. One was on I-95 doing 80 in a Camaro with four people inside when he felt a bad vibration. Rather then pulling over and checking he kept driving for another 5 miles, got off on the exit, and parked it because the vibration was HORRIBLE at that point. Every lug nut save one on the end of its threads were gone. Turns out they were metric nuts HE had installed.

The other was a Nissan 350Z also on I-95 and he hadn't torque the lug nuts on one of his wheels at all. His wheel came completely off and did a ton of damage to his car.

I'm paranoid about making SURE I tighten them down now.

100 ft/lbs sounds like a lot for a 7/16" stud.
