Dad taught auto mechanics for about 15 years. He had a girl a year or two ago beg him to change the tires on her car (for free mind you). They mounted, balanced the tires and 3 months later she was driving when she hit a pot hole and the studs broke. Her Dad said that they had overtightened the lugs even though they had used a torque wrench to install the lugnuts. The spineless school board decided it was just easier to write him a check instead of sticking up for what was right so he didn't have to pay a dime. No more privately owned cars in the shop.:werd:
