Does it shake while driving? Besides the popping,any other noises? Is it just going over bumps and turning?
Could very possibly be an inner tie-rod.How is your steering? Is it tight? Any loose spots? Does it turn on a dime? Meaning,does it turn with the slightest movement of the wheel?
You might also want to check the tightness of your steering rack.The metal sleeves that the mounting bolts pass through will eventually start shifting when the bushings wear.This creates a loud creak or pop noise.Most noticable turning a corner at moderate speeds or shifting the wheel back and forth while sitting still ( usually once or twice after the car sat a couple hours).
Could very well be a strut issue also.But don't quote me on that.Im not positive.I'm still dealing with some issues myself.
