A bottomhole assembly (BHA) has a first section, a second section, and a drilling motor disposed along the second BHA section. The first BHA section is connected to the second BHA section with a flex sub. A steering assembly positioned along the BHA includes a first steering unit and an axially spaced apart second unit. Each steering unit has at least one pad. During operation, the first steering unit generates a force in a first direction and the second steering unit generates a force in a second direction different from the first direction. The first and the second steering units thereby cooperate to axially misalign the first BHA section and the second BHA section at the flex sub.
