I'm gonna jump in on this squeak issue too. Gorhad does your truck squeak sound come from the wheel assemblies? I have an annoying squeak coming from the rear assemblies I believe. I only hear it when coasting through a parking lot. Once I touch the gas pedal, it goes away until I'm coasting again at parking lot speed. What can you not spray with wd40 or liquid wrench on an assembly?
I thought they made a spray specifically for brakes and was safe to squirt on the rotor or pads?
