Parts for your 2022 Subaru Impreza-Coil springs

2022 Subaru Impreza Coil Springs — Purpose, Care and When to Replace

Coil springs are absolutely used on the 2022 Subaru Impreza. Subaru’s own technical literature confirms it: the front suspension is a MacPherson strut with a coil spring, and the rear is a double wishbone layout with separate coil springs and shock absorbers. This layout is detailed in the Subaru Technical Information System (STIS) Service Manual for the 2017–2022 Impreza platform, and the Owner’s Manual describes the suspension type. Genuine Subaru parts catalogues also list front and rear coil springs specifically for the 2022 model year, so the part is very much relevant to this vehicle.

On this Impreza, the coil springs carry the vehicle’s weight, set the ride height and work with the shocks/struts to control body movement. They help keep tyres planted over rough Kiwi backroads and Aussie highways alike, smoothing out bumps and keeping steering and braking feel consistent. When they’re in good nick, owners get predictable handling, even tyre wear and a comfortable ride.

Coil springs aren’t a scheduled replacement item, but they should be checked at every service. Look for cracked paint, rust, sagging (lower ride height on one corner), broken end “pigtails” and uneven tyre wear. Noises like creaks or clunks over bumps can also point to a fatigued spring or a perished insulator. If the car often carries heavy loads or tows, fatigue can set in sooner.

When replacement is needed, it’s best practice to fit springs in axle pairs to keep the ride height and handling balanced. Quality matters—OE-spec springs will maintain factory ride and geometry, while heavy‑duty options can help if the car sees regular loads. Replace related hardware at the same time: top mounts/bearings, insulators and any single‑use nuts. Because springs store a lot of energy, a proper spring compressor and safe workshop procedure are non‑negotiable. After installation, torque suspension fasteners at normal ride height and book in a wheel alignment to prevent odd tyre wear and wandering.

Owners can keep an eye on things between services by measuring wheel arch heights side to side, listening for new noises and watching for sudden changes in ride comfort. Catching spring issues early saves shocks, tyres and alignment from premature wear.

• Inspect coil springs each service for corrosion, cracks and sag.
• Replace in pairs, renew mounts/insulators, align the wheels afterwards.
• Use OE or quality aftermarket springs matched to local driving and loads.

FAQs

How long do coil springs last on a 2022 Impreza?
There’s no fixed kilometre limit. Many last well over 150,000 km, but road conditions, loads and corrosion can shorten their life. Regular inspections at service time will spot issues before they affect handling or tyre wear.

What are the signs my Impreza’s coil springs need replacing?
Common signs include a lower ride height on one corner, clunks over bumps, uneven tyre wear, and visible rust or a broken coil end. If it starts to bottom out or feels floaty, get the suspension checked.

Do I need an alignment after replacing coil springs?
Yes. Changing springs alters ride height and can shift alignment angles. A post‑fitment wheel alignment helps maintain proper tyre wear and straight‑line stability.
