Lexus RX 270/350/450h Power Steering – EPS vs Hydraulic Malaysia

Earlier AL10 RX (2009–2015) uses hydraulic power steering — check for fluid leaks at the rack and hose connections; fluid type: Dexron III. EPS RX rack replacement: reconditioned. Hydraulic rack. Power steering pump (AL10 only).
Lexus RX Power Steering
- RX uses EPS — no hydraulic fluid; steering tuned for comfortable, light effort suited to family SUV use
- RX steering feel: slightly heavier than ES — SUV weight requires more robust EPS calibration
- EPS fault on RX: scan with Techstream — fault codes will distinguish between EPS motor, torque sensor, or ECU issue
- Tie rod ends and steering rack boots: inspect at 60,000 km — worn tie rods cause steering wander and uneven tyre wear
