Replaced lower control arm, all engine mounts, but still making popping noise when hitting bump, accelerating, decelerating and putting in gear sometimes.

This can be the sway bar links or frame mounts, or possibly the struts or strut mounts. Can you please shoot a quick video with your phone so I can hear the noise? that way I can tell for sure what's going on.. You can upload it here with your response.
