As I was changing the wheel, the bolt broke along with the pin. This was the second pin to break. The first one was right next to it. The car is a Toyota Duet EJ79 2003 model. It has four bolts when all of them are there on size 13s. I drove it back home which is about 5 Kilometres. I used it this morning to work about two kilometres from home and at lunch about 5km away. Then I will be driving home today after work. What kind of dangers am I putting myself in as I can not park it until I get it fixed probably two days time. Thanx.
