I failed you use my torque wrench. I'm sure that contributed to the issue. Pretty stupid on my part - no comments please!! What can I say - I'm learning as I go.

If anyone knows the correct torque setting, please let me know.

I see cars losing wheels every year as we have mandatory winter tire change every autumn and back to summer tires in april. People forget or don't realize they have to retorque alu wheels once after 60-100 miles. After that they are ok.

Even I myself almost lost a wheel 5 years ago when left front wheel nuts unscrewed themselves on my DD. Luckily heard a weird noise and stopped to inspect for a flat. Felt stupid because I knew I should have retorqued them but forgot.

No need to retorque steel wheels though.

Straight from the 2002 Corvette Service Manual. Besides, it's a lot less than the amount those idiots at the tire stores put on with their impact wrenches. Anything over 100 foot pounds risks warping the rim.

Steel rims from C3's are 80 foot pounds also taken from the 1972 Chevrolet Shop Manual.

I almost lost a weld wheel on my Cutlass I used to have for not tightening the the lug nuts up good. Fortunately I felt hte vibration and got off the interstate. If I remember right, I was down to only 2 loose lugs holding the wheel on, so yeah, recheck the tightening after some driving.

I had a strange clunking sound coming from my right front wheel on my 69 Mustang. A few months earlier I had coverted the car to front disc brakes, so I was concerned that something had broken loose. The car has the chrome rallye wheels with the little center caps. I pulled off the center cap and there was one of my lug nuts bouncing around inside the cap. Pretty embarassing, and I was sure I had tightened all of them, but I have to admit I must have missed one. I kind of like the suggestion above of torqueing just prior to putting the caps back on. If the cap is on, the lugs were torqued.

I've never had an issue with aluminum or steel wheels coming off. I do the same as mentioned previously by not putting the caps on until I tighten the lugs, just my reminder. I was also thinking about the loctite suggestion as well.

When you tighten, do you alternate the lug pattern? What I do is hand tighten the first lug, skip one, tighten the next one, skip one, tighten the next one and so on. I keep going and each time through the sequense I apply more torque. I don't use a torque wrench, but just use one of those cross shaped lug wrenches. I don't over-tighten them, but I do get them very snug. I know getting them off can be a challenge . . . you might even hear a grunt or two.

I always use a torque wrench because at 54, my musclemeter is just no longer reliable enough to provide an accurate measure of whether the nuts are all tightened the same.

Come to think of it, it never was that accurate.

I've never used a torque wrench on aluminum or the old mag style wheels and never had a problem, 35 years now, might go out and check mine right now though

I got a wheel bearing change on DD and immediately felt a vibration and took it back to the shop, they never tightened the lug nuts, you would think you get a real bad vibration before all the lug nuts backed off and the wheel fell off

my other vehicle that i am forced to drive in a service van ford E250

i had a wheel come off when making a turn ,,this was after having three new tires put on,,,i decided to use the full size spare wheel with tire that had never been used before,,,i torqued down the lugs,,,,the only thing that i could chalk it up to was that the rim was warped from sitting under neath the car for 6 years...hope this helps
