Vibration
My 2013 Chevy impala LTZ Has a vibration coming
from underneath when I’m traveling 20 mph or less.
Do you think it’s a buffer somewhere?
No the tires are in good shape. It’s more of a hum. It happened once before when I had a Malibu and when It got really bad it wound up being the heat shield on the catalytic converter. But I can’t seem to find anything loose underneath the car. It’s definitely something allowing the vibration to come through. Tires are balanced in good shape I don’t think it’s anything to do with the tires.
I found a video on YouTube, it’s a Toyota service video and vibrations and one of the things they indicated was depending on the Hertz level of the vibration would indicate where it was coming from. So I’m thinking that it’s one of the buffers that helps keep the sound from traveling into the cabin from the driveshaft.
