When was the last time you rotated your tires or had the brakes done, someone did not tighten the lug nuts down to 102 foot pounds of torque.
You should remover both the rear tires and inspect the rear lugs to make sure they were not damaged by having this happen. If any thread were damaged, get the lugs replaced.

 

Rear brakes were done 3 weeks ago. The lugs went back on fine. I removed the tire completely and re seated to be sure it was on right. I did notice that 4 of the 5 lug caps are loose that could definitely be why they weren't tightened enough.

 

Holy **** Dude. Someone was definitely sitting on your and your nine month olds shoulder. Damn.

 

When we sat down for dinner tonight and said prayer I had to give a special thanks cause I don't think we would be here right now if someone wasn't holding that tire on for us.

 

Glad all is well now, but if I were u I'd be going to that shop and freakn the f out on someone man!!! They owe you an explanation and some cake for sure.

 

Not sure if you did the brakes, or a shop, but sounds like that wheel was put on wrench tight, then they forgot to come around and torque them afterwards on that wheel. Be sure to now check ALL the wheels. Glad you are all safe...
