So, the shop I took it to was/is wrong. They said it was my front brakes. Now, I thought this was odd since the noise didn’t change when applying brakes but it was something I planned on doing this weekend, so I gave it a shot. I took a couple hours out of a busy day to replace the rotors and pads. Drove around some and guess what, still the same. I’ll be giving them a call in the morning, but probably ultimately going somewhere else.
