2022 Subaru Impreza Control Arms — What They Do and When to Replace

Control arms are absolutely used on the 2022 Subaru Impreza. Technical references including the Subaru Factory Service Manual (Chassis/Suspension), Subaru Global Platform suspension overview, and OEM parts catalogues list a MacPherson-strut front end with lower control arms (often called transverse links) and an independent rear with multiple links that function as control arms. That means “control-arms” is 100% relevant to this model.

On a 2022 Impreza, the front lower control arms link the steering knuckle to the subframe, letting the wheel move up and down while keeping alignment steady. Each arm houses bushings to absorb vibration and a ball joint to let the wheel pivot for steering. Together, they set and hold key geometry like caster and camber, so the car tracks straight, turns cleanly, and brakes without drama.

As the kilometres rack up—especially on corrugated roads and through potholes—bushes can crack or soften and ball joints can loosen. Tell-tales include clunks over bumps, a vague or wandering steering feel, braking shimmy, and uneven tyre wear on the inner or outer edges. A quick visual can help: look for split rubber, leaking bushing fluid (on fluid-filled types), or a torn ball-joint boot letting in red dust or water.

• Inspection: Have the front control arm bushes and ball joints checked at regular services (around every 15,000–20,000 km) or sooner if symptoms show up.
• Replacement tips: It’s wise to replace arms or bushes in left/right pairs for consistent handling. Quality OEM or reputable aftermarket arms are both fine, aluminium variants may save weight but the priority is correct fit and durability.
• Fitment fundamentals: Torque bushing bolts at normal ride height to avoid preloading and early bush failure. Replace any single‑use hardware and ensure ball-joint tapers seat cleanly.
• Alignment: Always book a four‑wheel alignment after control-arm work. Even tiny geometry shifts can chew out tyres and upset driver aids like ESC and lane-keep.
• While you’re there: Check sway-bar links, tie-rod ends, and front strut lower mounts. They often wear alongside control-arm components.

Keeping the Impreza’s control arms in good nick preserves steering precision, stability under braking, and even tyre wear—saving cash and keeping the drive feeling tight and confidence-inspiring. If it’s starting to knock, wander, or scrub tyres, it’s time to get those arms and bushes looked at.

Popular questions about 2022 Subaru Impreza control arms

How long do the control arm bushes and ball joints last?
In normal Aussie and Kiwi driving, they often last well past 80,000–120,000 km. Rough roads, heavy loads, and frequent speed humps can shorten that. If you notice vibration, clunks, or odd tyre wear, get them inspected sooner rather than later.

Do I need an alignment after changing control arms?
Yes. Even if the car drives straight after fitting, small geometry changes can accelerate tyre wear and affect stability control. A proper four‑wheel alignment locks in tyre life and handling feel.

Can worn control arms damage tyres?
They can. Excess play or soft bushes shift camber and caster, scrubbing the inner or outer shoulders. Sorting the arms early and aligning the car will protect those tyres and keep things safe.
