The 2019-2021 Subaru Forester utilizes a power steering rack and pinion system. This system >converts the rotational motion of the steering wheel into the linear motion needed to turn the vehicle’s wheels. It’s a key component of the steering and suspension system, and can be found in the 2019, 2020, and 2021 Subaru Forester models.
This type of steering system uses a toothed gear (the pinion) that meshes with a toothed bar (the rack). When the steering wheel is turned, the pinion rotates, moving the rack linearly.
The power steering system provides assistance to the driver, reducing the amount of effort needed to turn the steering wheel, especially at low speeds.
The 2019-2021 Subaru Forester models all use this power steering rack and pinion system.
The Subaru Forester’s power steering rack and pinion, specifically for the 2019-2021 models, is a critical component in the steering system. It converts the rotational motion of the steering wheel into the linear motion needed to steer the vehicle. The rack and pinion assembly, along with other steering components like the tie rod ends and bellows, work together to provide precise and responsive steering.
The rack and pinion mechanism translates the driver’s steering input into the movement of the front wheels, allowing for directional changes.
It includes a pinion gear that meshes with a toothed rack, and the assembly is often paired with tie rod ends, bellows (or boots), and mounting bushings.
For the 2019-2021 Subaru Forester, the power steering rack and pinion, including part number 34110SJ040, is designed for the 2.5L H4 engine and is compatible with various trim levels like Base, Limited, Premium, Sport, and Touring, according to parts listings.
Some common problems include leaks in the tie rod boots, stiffness in steering, or unusual noises, which may indicate a need for replacement or repair.
Certain Forester models, particularly the 2019 and later, utilize EPS, which provides power assistance electronically rather than hydraulically. This system includes a motor and control unit within the rack and pinion assembly.
