this is why I have made it a habit to get a flashlight and inspect under the truck and under the hood about once a month for remnants of or whole stop signs, I drive her kind of hard so I need to catch things like this as early as possible. I check all the seals and bushings, all the suspension parts, brake calipers, u-joints. under the hood I look for leaks or rubbing hoses or wires, check my tires for nails or screws. Anytime I have it jacked up I check the wheel hubs, if I take it to have the tires rotated (since it's free) I take the opportunity to check stuff up close then also.
