Do have to raise the motor in a 1995 Chevy 4x4 remove oil pan?

No, you generally do *not* have to raise the motor in a 1995 Chevy 4x4 to remove the oil pan. However, it depends on the specific engine and your access. While there's usually enough room to lower the oil pan, some modifications like lower suspension components or aftermarket accessories might make it tighter. It's advisable to consult a repair manual specific to your truck's engine (e.g., a small-block Chevy or a Vortec V6) to be certain.
