I previously asked this question as my passenger side wheel fell off with a broken stud. What can cause a wheel to fall off/hub to break?
After repairing it the mechanic checked the other wheels and said he found the driver side stud had snapped as well(though the wheel hadn't fallen off). He said he recommends I should replace all 3 hubs or all the studs on the other hubs.
1) What would have caused the passenger side stud to snap too, would it again have been loose nuts(none of which have fallen off as far as I could see) or would the impact from the car falling to one side cause the driver side stud to snap too? what would have caused it?
2) Is the mechanic right in telling me to change all studs rather than just the snapped ones, I think he is suggesting the may have rusted away but I don't remember seeing any rust or maybe he is saying they could the accident could have impacted all the studs?
3) Shouldn't the mechanic have checked all studs and further damages before fixing the first hub or, given the situation, is it normal to unravel things as you go?
