Helped a friend by changing over her wheels for winter, was adamant about coming back for a retorque. Offered to go to her. She drove to Toronto and back a week later, and last night noticed some minor shaking while driving a short distance. Didn't tell me about it. This morning the shaking got worse so she pulled over - her front passenger side wheel was still "on" but 4/5 lugnuts missing.
Could have been so much worse, but I know I did nothing wrong - the lugnuts were rusty as
and i knew they'd loosen, which is why I mentioned the retorque 4 times.
... She's being really good about it and still wants me to help her in the spring, but I'm pissed at myself for not showing up at her house and retorquing when I had a chance. Not my responsibility, but this is a matter between friends, not legality.
