Knocking noise from under car.

Next problem I have is this. Just last week I started hearing a popping noise coming from underneath the front of my car. It kind of sounds like something is hitting against the bottom of the car. At first it sounded like it was coming from the right front, but now it kinda sounds like both sides. Any idea where I should start looking?

Check stabilizer bar end links.

Maybe exhaust hangars too while you're looking.

I have had this same problem forever! I have checked about every bushing, mount, etc that I could find to no avail. It happens when I switch from reverse to drive, and vice/versa, and sometimes (although rarely) when I hit a bump with the wheels turned. I don't know where else to look.
