I have this issue with my CX7, when I drive at a regular speed, the car performs very well. Now when I release the gas pedal and brake the car makes no sound until it goes below 20 MPH, then I can hear a metallic pulsating sound coming from the front left side (driver side). I changed the sway bar links and the tie rod ends. I checked the brakes and they seem perfect (shoes are not worn).
Any ideas of what this might be?
Just in case it's not the timing chain, I already changed it.
