I have been pleasantly surprised that my experience with the TSB - although unnecessarily cumbersome - has proven to work. In fact, it's worked so well, I don't even think about the squeal anymore.
I bought my TRD Sport 2WD in South Louisiana in early August - the pinnacle of humidity. I have since temporarily relocated to the DC area for work, so I blindly picked Alexandria Toyota to check out the problem, since they're closest to me. On the phone, they said they hadn't heard of this issue, but insisted I bring it in.
Appointment #1 was their confirmation of the problem, and their [false] diagnosis that it was coming from the rear brakes. I wasn't trying to burn bridges, so I indulged their theory and said "the Forum disagrees with you, but you do you." I even showed them the TSB, which they hadn't seen. They ordered parts for the rear brakes, no cost to me.
Appointment #2 was the installation of those rear brakes, and, to the surprise of no one here, the realization they hadn't solved the problem. So they ordered the parts for the front brakes according to the TSB and scheduled another appointment, no cost to me.
Appointment #3 was the installation of those new front brakes, no cost to me.
Thankfully, I never had issues with backorders. This whole process took just under a month. And now I can safely say - after two months of parking outside in the cold and the rain, after going through the carwash, and after dozens of drives after periods of inactivity - that this squeal is not happening anymore. Could be the change of scenery, or just a lucky good batch of parts, or both.
