So, my wife drives the suburban as her daily vehicle and she said there's a squeak coming from the front left wheel. It only starts when it gets warmed up from about 15mins of driving. She took it to our local mechanic we typically use and he investigated the brakes and stated it wasn't them...but since the truck was only driven about 10 mins, the noise wasn't evident. It's getting worse, and it doesn't look like the brakes to me. Bearing? thoughts? I'm going to pick up my trailer on thursday and i don't want any hiccups
