I have a 1998 GZMC Jimmy. Recently it started to rattle but only upon acceleration and driveing. Today however, it has began to vibrate badly. The whole truck vibrates. You can feel the vibration hen accelerating, driving and when in park. I'm really nervouse because this is my only mode of transportation and I have little money to fix. It is a 4wd.

gonna need a little more info, it shakes while in park? that tells me that the engine has a mis fire possibly on one or more of it's cylinders..I would check to see if all of the spark plugs wires were still attached firmly, there should be 4 spark plug wires, and 1 coil wire..moisture in those wires will also produce a bad mis..how long has it been since its last tune up??
