andito uli ako, and another problem on our spacegear...
anyway whenever we encounter some humps or yun cemented roads... naririnig ko from the inside cabin yun mga squeaks ng springs. i also hear them whenever I rock the van from the outside...
Yeah, and after springs have "taken a set" (which is after a few weeks), unless you really overload your car, they really should last a looooooong time....
Try to check the shock mounts, bushings and or door/hood hinges. There are so many factors to consider and not only the springs. Usually, the springs are the last to squeak in my opinion because of the weight it bears unless it has full contact with a metal strip or something.
