From the way the shadows are falling, they look to be cupping slightly, so it looks to be alignment wear.
But I recently found a problem with my setup. My chain is rated for 520 lbs, the turnbuckle at 320, and I think the buckles I used to attach the chain to the turnbuckle and spring perches were around 250. Apparently, that wasn't strong enough, and they bent pretty bad on me. Just installed some beefier buckles today, rated at 1400 lbs I believe, which is definitely more than I need, but hopefully it'll hold better now. Seems like when one tire goes over a bump, it changes the distance between the spring perches, so it stretched the parts beyond their capacity. The current weakest link is the turnbuckle now.
Bad news is while resetting my front alignment since my steering wheel was a hair off, my hand slipped off my wrench and hit something, causing whatever I hit to fillet my thumb open right at the base joint. Should probably have gone to get a few stitches on it, but I was doing unauthorized repairs to my own car at work, so I picked up some butterflies to hold it closed. Good thing I also know first aid!
