Failure
While there is no exact lifespan that can be put on sealed ball joints, they can fail as early as 80,000 miles in modern vehicles, and much sooner in older vehicles. Signs of a failing ball joint start with a clicking, popping or snapping sound when the wheel is turned and eventually turn into a squeaking sound at the end of a stop, when the gas pedal is used and/or also when hitting bumps. Another symptom could be 'thud' noises coming from front suspension when going over bumps. Dry ball joints have dramatically increased friction and can cause the steering to stick or be more difficult.
If a ball joint fails, the results can be dangerous as the wheel's angle becomes unconstrained, causing loss of control. Because the tire will be at an unintended angle, the vehicle will come to an abrupt halt, damaging the tires. Also, during failure, debris can damage other parts of the vehicle.

Famous quotes containing the word failure:
“Moralists love to discourse on the hollowness of success; about the hollowness of failure they are silent.”
—Mason Cooley (b. 1927)
“Slowly the poison the whole blood stream fills.
It is not the effort nor the failure tires.

“Scientific method is the way to truth, but it affords, even in
principle, no unique definition of truth. Any so-called pragmatic
