Click and Clack had a call about a similar issue last weekend. The caller had duct taped a failed suspension joint together and was continuing to drive the car. They commented that they hear lots of stories of ball joint failures in parking lots but few stories about high speed failures. They speculated that this inbalance in stories was explained by the fact that the people who had ball joints fail at high speed are no longer around to talk about it.
