Parts for your 2019 Subaru Impreza-Steering bushes

2019 Subaru Impreza steering bushes — what they do and when to replace them

Based on Subaru’s 2019MY Impreza Service Manual (Steering section) and OEM parts catalogues for the GK/GT platform, the 2019 Subaru Impreza runs a rack-and-pinion with electric power assist that’s mounted to the front crossmember using rubber isolator bushings (often called steering rack bushes). These bushings are a standard fit and aren’t a delete-only item, so steering bushes are absolutely relevant to this model.

On this Impreza, the steering bushes cushion the rack against the subframe, filtering vibration from the road while keeping the rack accurately located. The aim is sharp on-centre feel without the buzz or clunks that would come from a hard-mounted rack. Over time, heat, load, and road grime can harden or crack the rubber. When that happens, the driver might notice vague steering, a knock on turn-in or over bumps, tramlining, or uneven tyre wear. Left too long, a sloppy rack mount can accelerate wear elsewhere in the steering.

As part of regular servicing, a good workshop will:

• Inspect the rack-to-subframe bushes for perishing, cracking, or oil contamination.
• Check for movement while an assistant lightly rocks the steering wheel with the engine running.
• Listen for clunks as the front suspension is loaded and unloaded.

Replacement is straightforward for a trained tech: the rack is supported, the mount brackets are removed, old bushes are pressed out, and new OEM or quality aftermarket bushes are pressed in, then everything is torqued to spec from the Subaru manual. It’s smart to recheck front-end alignment afterwards, as fresh bushes can slightly change rack position. If the car sees rough roads or spirited weekend drives, performance polyurethane bushes can tighten response, though they may pass a touch more vibration through the wheel. For daily commuting comfort, fresh OEM-style rubber is a safe bet.

There’s no fixed kilometre interval for steering bushes, but many will need attention somewhere after 100,000–150,000 km depending on use. Signs that push it up the priority list include new front-end knocks, steering wander, or visible deterioration. Keeping leaks in check is key too—engine oil and power steering fluid (where applicable) can attack rubber and shorten bush life.

FAQs

Do 2019 Subaru Imprezas actually have steering bushes?
Yes. Subaru’s service documentation for the GK/GT platform shows the electric power steering rack mounted via rubber isolator bushings on the front crossmember. They’re a normal wear item and can be replaced separately from the rack.

How often should steering bushes be replaced on a 2019 Impreza?
There’s no set interval. Expect inspection at every service and replacement when worn—often after 100,000–150,000 km, sooner with rough roads, big wheels, or if the bushes have been soaked in oil.

What are the symptoms of worn steering rack bushes?
Common signs include a dull knock over bumps, vague on-centre feel, tramlining, and uneven front tyre wear. If movement is seen at the rack mounts while the wheel is rocked, the bushes are due.
