I have learned in a short period of time that different noises need attention immediately and some noises mean nothing at all.
I learned a loud squeal noise when turning the steering wheel with smoke coming out under the front end means an idler pulley is going bad. I learned a gurgling noise from the bathroom means water was left running and it is over filling my black tank
I also learned a loud noise coming from the right rear is not a jar of peanut butter falling onto the counter, but was a tire blowing out.
Anybody else hear noises that you should or should not be concerned about?
