2018 Subaru Impreza Suspension Bushes — What They Do and When to Replace

Based on Subaru’s workshop manual for the 2018 GK/GT Impreza (Suspension section), the Subaru Global Platform suspension layout, and OEM parts catalogues, this model definitely uses multiple suspension bushes. They’re fitted to the front lower control arms, rear double-wishbone links, anti-roll bars, subframes, and various mounting points. Aftermarket catalogues for the 2018 Impreza also list replacement bushings, confirming they’re a normal service item on this car.

On the 2018 Impreza, bushes are the quiet heroes that keep the ride tidy. They’re rubber (sometimes fluid-filled/hydraulic) or polyurethane mounts that isolate noise and vibration while allowing controlled movement of arms and links. That lets the suspension articulate smoothly, keeps alignment steady, and stops knocks transmitting into the cabin. In short, good bushes mean sharper steering feel, better tyre life, and that calm, planted Subaru ride.

Because Aussie and Kiwi roads can be tough, bushes are worth a regular look during scheduled servicing. Tell-tales of worn bushes include vague steering on the motorway, clunks over speed humps, uneven or feathered tyre wear, and front-end shimmy under braking. Front lower control arm rear bushes on these cars are often hydraulic and can leak or crack as they age, which shows up as a dull thud and wandering feel.

• Inspection: Check each service for splits, tears, oil contamination, and (for hydraulic types) fluid seepage.
• Replacement approach: Many bushes can be pressed in, but complete arms are sometimes the smarter option for time and alignment accuracy.
• Alignment: Always book a four-wheel alignment after bush work to reset camber/caster/toe.
• Torque at ride height: Nip everything up with the car at normal ride height to avoid preloading the rubber.
• Material choice: OE-style rubber keeps it comfy and quiet
