Swingarm alignment?

[Shainman]

Hey y'all,

My rear wheel has become off center.

I think it has progressively moved over several weeks. First I noticed, after riding, the "dirty" (the area that touches the road) part of the tire was slightly off center to the left. I thought it may be due to that last turn into the driveway. My tire alignment seemed ok. The measurements from the center of the pivot arm to the center of the axle were the same. The bike rode fine; nice and straight, no pulling.

Today I noticed that the tire had scrubbed against the upper inside fender (there's a bit of tube framing up there). I think only when the shocks are compressed after a bump, but I can't be sure.

Today I removed and replaced the rear tire looking for something to account for this problem. All the parts are assembled in the proper order.

Is this an issue with the shocks? Can the swingarm be adjusted into alignment?

Here are some pictures from after today's reassembly.
