Flexible Coupling for Toyota EPS Motor Shaft (Part Numbers: 45235-28130 / 45254-28040)
The flexible coupling—also referred to as the steering damper—is a small yet essential rubber component used in the Electric Power Steering (EPS) system of many Toyota and Lexus vehicles. Positioned between the EPS motor and the steering shaft, its main function is to absorb vibrations, reduce steering noise, and eliminate excess play in the steering wheel.
Over time, this coupling can wear out due to constant motion and torque, leading to noticeable symptoms such as clunking noises, reduced steering precision, or a loose steering feel. It’s a common issue in models like the Toyota Camry, Corolla, Prius, and Lexus ES and RX series.
