Q: Strange feeling/noise under driver side/ foot rest after slamming on the brakes?

asked by on

Hi, Just recently I had to slam on the brakes which i have not had to do in probably well over a year as I was cut off by this truck. I've been driving for over 30-years and this noise/bump totally caught me off guard. When I slammed on the brakes, it felt as if something flipped up and banged the undercarriage, under my feet (driver side), I felt a bang or thud. It does not happen when I brake normally, either softly or aggressively in traffic. Any possible idea of what could cause that sensation?

My car has 127000 miles.
My car has an automatic transmission.

It sounds like this may be a problem in the suspension. I would think the noise is coming from the lower control arm inner mount bushings. I would have the front control arms and suspension inspected to see if you have any bad or worn bushings. If you need help with this, a technician from YourMechanic can come to your home or office and perform any needed services.
