My daughter's escort (auto transmission) is making a single (had hard to hear, for me at least) clunk when she hits the accelerator hard going 50 mph or above. She says it sounds like a card flapping in bicycle spokes, but it sounds like a U-joint just starting to go out on a car with a driveshaft. She wants to take it into the local garage, but I'd like to know what it might be before they give her a potentially expensive diagnosis.
Any ideas? Thanks in advance.
