Popping sound under left side

Just thought I'd check to see if anyone knows anything about this... I'm driving a '95 Integra, all stock, and haven't had any problems with it until recently. Last time I started my car, I noticed a popping sound under the left side of the car (while sitting in the driver's seat.)

I checked my oil and everything is fine there. It pops even when it is in idle, and gets louder and softer randomly (doesn't matter how fast I'm going.) I don't notice any other problems, though. My car drives exactly the same and, just in case it matters, turning doesn't change the sound or frequency of the popping. Let me know if you can help me out. Thanks!

BTW, its under the hood... right by the engine..

need more details. length of popping, frequency, does it occur after turning on A/C? tell us what seems to trigger it. Be as specific as possible from where it comes from, and describe it? Like a flat tire, popcorn, a bowling ball in your trunk. Be specific.

It only makes the popping noise when the car is in motion or making turns? Sounds like the axles. Have you checked the cv boots for tears or rips?
