It's been a while, but I've been able to rule out the foglamp and brake pads as potential cause.
I also finally got around to lifting the driver's side front wheel to check for any play around the wheel area. Couldn't find anything loose in the wheel arch, but I did notice some play in the wheel:
Is this normal? It felt like it was just the column bumping into the steering lock, I could see the steering wheel move a bit as I was fumbling with the wheel. It's the only "loose" thing I could find in this area.
