Just bought an 02 frontier sc extended bed, all the goodies. I just love this truck. But already finding a few problems, and with this truck being so new to me I have no idea how the systems are supposed to operate. The biggest problem that i have is that there is a vibration noise coming from the engine compartment after you start the vehicle, take it out of park and drive. Forward and reverse, and the only way to duplicate it, is to shut the truck off and repeat the process. Happens everytime. But now the same noise is coming during heavy breaking over bumps. Sounds like an accumulator pump or something. During the start procedure i could live with, knowing it is not right, but when it involves the breaking, i want to be sure what it is. Hey, thanks for any input that you might have.
