Over the last year or so, my front suspension has been developing a popping sound. It only happens after I've been driving for about 10-15 minutes, and you can hear it sitting still turning the wheel (either direction), and driving over bumps / turning. I had my girlfriend turn the wheel while I was looking around and I didn't see what was popping but I could feel it the most when grabbing the inner tie rod.
The outer tie rods were replaced about a year ago, inner tie rods and struts a few months ago, and I don't have a front swaybar so endlinks are out of the question. I looked over the ball joints and the A-arm bushings; the hydraulic bushing has some cracking but there was no movement when hearing the popping. Also I don't know if it changes much, but the popping is way more obvious from inside than outside.
