One of my daughters had a rotating noise coming from left front. Car is an '06 SC. It began as a slight rub / squeal and I put it down to brake pad noise. It got more pronounced - enough so that she called me about it, but now she described louder scraping and a click with every rotation of the wheel at slow speed.
Driven around a parking lot - sure enough rubbing and a click. But the click didn't seem to vary with turning left or right.
I put the car on jackstands. No apparent slop in wheel bearing. Took off wheel, and could tell rotating by hand that here was some scraping. There was nothing wrong with either outer or inner CV boots. With wheel off and engine at idle (carefully) the scrape was evident, and when brakes were applied there was click/clunk at one point.
I removed caliper (not carrier) and inspected rotor and pads. No 'adhesions' on back side of rotor. Pads were put on new by PO to sell the car - they were in very good shape and nearly new, but I found no lube/silencer on the backs. I looked over the disk and caliper, and I saw what appeared to be some shiny spots showing through the edge rust on the disk and the caliper. I took a file to both. With the caliper off you can put a file squarely across the disk edge. I did the rotor edge in about 8 segments and tried to keep it all even, but I wasn't removing so much material that I would likely affect balance anyway.
Put it all back together and replaced the wheel. Torqued the bolts and much to my satisfaction the scraping was gone. To my pleasant surprise, so was the clicking. I got to drive the car 40 miles back to my daughter's house later in the day, and it seems fine.
Posting this because I didn't find exactly this scenario when I searched, AND I can imagine that many like me would be worrying about wheel bearings and CV joints. Thankfully neither of them in this case!
