2 Before installing the other parts, we wanted to install the new torque arm kit (part no. 2217), since the factory arm was already out of our car. The first step was to support the rear end and body using pole jacks, with the car on our drive on lift. If you don't have a lift, then support the car with jack stands on the body subframe, and use a jack to support the rear. This unloads the rear suspension, necessary for the swap.
