I just finished replacing both front wheel bearings in my 2016 Subaru outback because they were making a bad warbling noise. I did the passenger side first and tried just about everything I could think of to get the hub out with no success before deciding to pull the knuckle and hammer it out on my bench, so I started by doing this on the driver's side and it went much smoother. I also ended up replacing both lower ball joints while I had the knuckles out.

However, when test driving the car I heard an intermittent squealing noise that seems to be coming from my passenger side. It only starts after about 20 minutes of driving, and I can't reliably reproduce it. Sometimes it's when turning (usually between 10-20⁰ to the right), sometimes when braking. It usually goes away within a few seconds of taking my foot off the brake and straightening the wheel, but sometimes it continues for longer. To me it sounds like something rubbing against the rotating assembly, almost like a pad wear indicator. I checked the brake heat shield for bends from being whacked by a wayward hammer blow but it looks okay. Does anyone have any advice on what could be making this noise?
