The Lexus ES300 Steering Rack is a component of the total steering mechanism in your car. When you turn the steering wheel, the force you exert goes to the pinion gear. The pinion gear is fastened to the steering wheel with a shaft that transfers the force to the steering rack where the teeth on both components interlock where the rotating motion becomes a back and forth motion.

The rack has a tie rod at the end that either pushes or pulls the spindle that then turns the wheels. The rack and pinion gear assemblies, along with the power assist pinion are contained in the rack and pinion housing.

It serves two purposes; one is converting the circular action of the steering wheel into the lateral motion needed to turn the wheels. It is also a gear reducer, enabling you to turn the wheels much easier.

If your car becomes hard to steer, especially at low speeds or you hear a low hissing sound, your might need to replace your Lexus ES300 Steering Rack.
