Correct, mine is also internal to the cab.Maliburider said:I have the same problem with my 08. Its like a deeper squeak sound like the pedal hinge needs lubrication. It seems to happen worse when its warmer out. I have drenched it with wd40 and still cannot get it to go away. I know its internal to the cab and not brakes or rotors etc. It does go away sometimes.
