How wide is your stance? I would perhaps pull it in an inch on each side and see if it helps.
Wouldn't hurt to get a video up either and let us take a look.
My stance is a little wider than shoulder width, maybe a little more somtimes. I have been recently focusing on pushing my knees out when driving up, so they dont buckle in. I could be opening my knees out too much as you mentioned. I don't really have a way to record myself at the moment, but possible... I'll be doing back squats tomorrow, I'll start out light and work my way up and focus on form.
