As stated above - bent dust shield. I just swapped out my shocks (as you'd do for mid-perch) and bent my shield a little bit putting the new ones back in. When you do it, it's easy to see how it would happen, but I won't bore you with the details. Suffice it to say, JUST happened to me. I had the whooshing and a squeal at full right turn. I had to get back in there anyway for some stuff and found it. Easy fix, I just bent it back with my hand. You should be able to just reach around and bend it back without even taking the wheel off. It shouldn't take much, just yank it a bit until it moves slightly. There is no precision.
