Forgat to check my wheels..

[t_marat]

Today at 120kmh I start to feel some vibration. Slow down, and hear some noise, kind of clicking, coming from the back of the car. At first thought the tire must be blown!! But look around and see all tires are good. Have a closer look at a rear left wheel. One bolt is missing! The other is hanging out, I take it out with my finger! Its broken, the inner part is left inside.
Lift the car and try to tighten other bolts with a wrench (or whatever it is called). Two are loose, the third seems to be tight, but I see that it is not holding the wheel firmly and does not turn either way. Put a little more force with my hand, and now it is also broken.. The inner parts are left inside the hole..
Now I have just two bolts to hold the wheel, which also happenned to be in a row, one adjacent to the other! Three other holes for bolts are filled with leftovers from what was there before.
Tried to drive with just two bolts; put in first gear and go in idle mode. Seconds after the wheel starts making clicking noises, and feel that it is acting as a brake. Feels like the remaining two bolts are about to get ripped off.
I was 25km away from the city. Called the evacuation car, had to transport the car back to city.
Checked all the other wheels, all are OK, very tight. The last time those wheels were taken off was in winter, to put winter tires, both rear wheels. Since then nobody, nor me neither anybody else who drove the car, touched them.
So they become loose with time, right? If only I had checked them before going out, would have saved me a lot of trouble.

have any enemies that might have loosened them for you? Your lucky the wheel didnt fall off and crush the fender/door or Q panel!

ditto,
That's a good old dirty trick!
You are very lucky it didn't come off at speed, lock up the back and spin you out of control.

I don't think I have enemies who would do such a thing.

Do those bolts loosen by time themselves? Did you ever noticed such a thing?

[Alexlind123]

They should never loosen over time...perhaps they were not torqued properly when they were installed.

[632 Regal]

or they had oil on them, these should be installed DRY.

The same guy torqued both rear wheels back in February. It was very cold back then. No oil.
Must have been improperly torqued.

Going with this theory.

[BillionPa]

were they installed with metallic anti-sieze compound?

overtorqued perhaps on the ones that broke if the lugnuts were cheap.

were they installed with metallic anti-sieze compound?

Is that a bad thing?
