2000 Nissan Sentra, 100K miles
Audio clip taken from inside the car: https://vocaroo.com/i/s1JMhQ1vgd6E
A medium to high pitch scraping noise, definitely seems "rotational." No big change in the noise if I step quickly on the brake or gas -- it just gets faster or slower as the car gets faster or slower (whether coasting or braking). Sound quiet on the recording but is very audible in real life.
Should I be concerned about a noise like this if the goal is to drive 10-20 miles per week for a year and then get rid of the car?
