Spent 5 hours hunting a rattle that turned out to be a $2 quarter wedged in the seat rail
Last Thursday a guy brought in his Honda CR-V complaining about a clunk every time he turned right, so I pulled the door panel, checked the sway bar links, and even swapped the strut mount thinking it was shot. Turns out his kid dropped a quarter in the seat track back in March and it was rolling around the whole time, which I only found after I gave up and vacuumed the carpet. What is the dumbest non-mechanical thing you have ever spent half a day chasing?
