Customer Question

Hey. My car started making a knocking noise as I drive today. I went to bring it to my mechanic driving really slow, 20 mph, and I heard a bang. Started to knock even louder and the car started to move back and forth as I drove. Steering wheel was harder to keep straight as well. Car rocked and made the banging noises entire time to mechanic. What could this be?

What has your mechanic said about it?
