Haha yeah I got lucky, my last OB was much more rusty and harder to work on. My guess is a lot of these components like the rotors/calipers and possibly other suspension parts were changed at some point, probably when he welded the last strut or changed the wheels. There are some rusty parts but I’m thankful it’s not too bad, i think the car spent a lot of time in forida too.Did you replace the strut mounts? I had a knock on one side of my mazda3 about 5k miles after replacing my struts. Turns out I had a bad strut mount which I obviously should've replaced when I put in the new struts. They seemed smooth/fine when I replaced the struts but 5k miles later and one of them was no longer smooth.
Try bouncing the car and see if you can illicit the same noise. If you can then have someone else bounce the car while you try and pin point said noise.
Btw, how the heck do you have a '99 Subaru which looks cleaner underneath and less rust then a 1 year old subaru from southern ontario?!
Strut mounts are brand new, bought them loaded/complete so I didnt reuse any old parts and because I also don’t have the tools to compress springs and reuse the old strut parts, I didn’t really want to anyone I just wanted brand new ones. I’m guessing something something is loose, it could possibly even be a brake/caliper part as I’ve heard it knock when not going over bumps, just coming to a stop and my tires bumping the curb.
