Take the play and wander out of tired steering with the Atlantic Automotive Engineering Rack and Pinion Assembly 3578N, a direct-fit replacement for the 2004-2010 Toyota Sienna. A rack and pinion assembly converts the rotation of your steering wheel into the side-to-side motion that turns the front wheels, transmitting your input through the pinion gear to the toothed rack.
Core steering function: Translates steering-wheel rotation into the linear rack movement that steers the front wheels for controlled, predictable handling.
Signs this part may need replacing: Fluid leaks, hard or uneven steering effort, excessive play or wander, clunking when turning, or uneven front tire wear can point to a worn rack and pinion.
Application-matched: Designed to replace the original rack and pinion on the listed Toyota Sienna applications.
If a failed rack and pinion is the cause of your steering complaint, this assembly replaces the original unit; diagnose the source of the symptom before ordering, since play and leaks can also come from other steering and suspension components. A wheel alignment is recommended after installation.
