“Wash charge has been deducted from your parts and labor total for billing purposes”
Hum or growl that rises with speed
Speed-proportional hum is the wheel-bearing signature — it changes when you swerve gently, loading one side then the other. Tire wear patterns make the same sound; both live at the wheel end that dominates these outcomes.
Squeal from the engine bay
A squeal at startup or with the A/C on is belt territory — the serpentine belt or its tensioner — one of the most common and least expensive findings.
Grinding tied to braking
If the noise changes when you touch the brake pedal, it's a brake-noise visit — see the brake outcomes, where pads and rotors dominate.
