Probably, but the method depends on the type of slide mechanism. In a 2002 chances are the slide is either HWH or Power Gear. Is it hydraulic or rack & pinion gear (driven by electric motor)? Please tell us more.
Rack & pinion gear types usually adjust the height of the outer end, while the inner edge height is controlled by a physical shim underneath, e.g. a roller or a pad of some sort. I'm wondering if you may have broken or lost these shims that it rests on.
