Not necessarily, no. I have a pretty decent squeak going on in the front brakes because the drivers side pad anti-rattle spring is out. There were some extenuating circumstances which led to my removing it due to noise (warped front rotors), but that may be something to look at if you haven't been into the brakes recently. Also bear in mind that these cars are normally very hard on brakes, and braking parameters can change very rapidly depending on driving style and the quality of the brake components on the car. But I know I need to replace brakes, so I know what this is. In this case, I would be willing to bet it is centralized in either the brakes or a ball joint. But if it's a constant squeak, probably brakes. I'd go over all of the front end wear items, as Mark VIII's just love to eat them all up. Got a '96 here, just so you know..
