1. Draw a free body diagram of the vehicle, including the weight acting at the CG, each wheels' reaction force. The inertial force is located at the CG and acts opposite to the direction of the acceleration (
2. The two equations that need to be satisfied are balance of forces, and balance of moments. Balancing the moments is easier if you take moments about one of the wheels rather than the CG. If you want the steady state weight transfer, then the angular acceleration is zero.
