Maybe one of your tires is low on air? 130,000 w stock suspension? I'd be looking at front sway bar end links. Since they're rubber they tend to crack and break over time. Could you post a pic of the car leaning?
Back when I took my stock springs out of my car it had a slight lean to it as well and come to find out when I was taking the springs out to cut them one was actually rusted and broken on the bottom coil. So id check that out, hope this helps!
