## Abstract

An integrated vehicle jacking assembly includes a plurality of jacks that is each coupled to a bottom side of a vehicle. Each of the jacks is actuatable into an extended position for lifting a respective driver's side or passenger's side of the vehicle upwardly thereby facilitating tires on the respective driver's side or passenger's side of the vehicle to be removed and replaced. A control unit is positioned within the vehicle and the control unit is operationally coupled to each of the jacks. The control unit actuates one or both of the jacks between the extended position and the retracted position. A plurality of wheel chocks is provided for inhibiting the vehicle from rolling when the vehicle is lifted.
