In this Tech Tip Short, Erik Screeden breaks down what technicians need to understand about electric power steering (EPS) and how evolving component design is reshaping modern service approaches.
Screeden explains how today’s systems are calibrated to operate within a specific friction range. When that balance is disrupted — whether from wear, contamination, or poor-quality parts — technicians may encounter issues like increased steering effort, warning messages, or faults tied to EPS torque sensor diagnostics. These challenges highlight why low-friction steering components, including advanced bearings and improved sealing designs, are critical to maintaining proper system function.
For shops focused on automotive steering repair, understanding how component quality influences system behavior is more important than ever. Screeden emphasizes that effective steering system diagnostics now require a holistic view — looking beyond individual parts to how the entire system works together.
