Parts for your 2017 Subaru Outback-Coil springs

2017 Subaru Outback coil springs: what they do and when to replace them

Coil springs are absolutely relevant to the 2017 Subaru Outback. Technical sources confirm this: the Subaru service manual for the BS-series Outback lists a MacPherson-strut front suspension with a coil spring, and a rear double-wishbone layout with a shock absorber and separate coil spring. The Subaru global parts catalogue for MY2017 Outback also lists front and rear coil springs by variant, and major aftermarket fitment guides (KYB, Monroe) catalogue coil springs and strut assemblies for this model year. So, the Outback runs coil springs at both ends.

On a 2017 Outback, the coil springs carry the vehicle’s weight, set its ride height, and team with the dampers to keep tyres planted over corrugations, potholes and gravel. They’re key to ground clearance and to how the wagon behaves with a load in the boot, a towbar fitted, or a family on board. When springs lose rate or break, the car can sag, scrape more readily, and the Symmetrical AWD doesn’t get the even, predictable contact it was designed for.

Coil springs don’t have a fixed replacement interval, but they should be inspected at regular services (every 10,000–15,000 kilometres is common in ANZ). Look for chipped powder-coat, deep rust, a cracked or missing pigtail end, or a noticeable lean side-to-side. A thud over bumps, changes in ride height, or uneven tyre wear can also point to a tired or broken spring.

• Always replace springs in axle pairs to keep rate and height consistent.
• If the Outback regularly tows or carries gear, consider heavy‑duty springs matched to appropriate dampers, keeping legal ride height and alignment specs in mind.
• Check related parts: strut top mounts, rubber isolators, bump stops and dust boots. Worn mounts can add noise and misalignment.
• Use a quality spring compressor and follow workshop manual torque specs, tighten control arm and strut bolts at normal ride height to avoid bush preload.
• Book a four‑wheel alignment after spring or strut work, ride height changes alter camber and toe.

In Australian and New Zealand conditions—coastal air, gravel roads, and occasional salt exposure—surface corrosion can start where the coating chips. Keeping the underbody clean, avoiding overloads, and addressing any clunks early will help coil springs live a long life. When it’s time to replace, sticking with OE‑equivalent rate and free length (unless purposefully upgrading) preserves the Outback’s balanced handling and factory ground clearance.

Popular questions about 2017 Subaru Outback coil springs

Do 2017 Outbacks use the same coil springs front and rear?
Not exactly. Front springs sit over the MacPherson strut and have different rates and dimensions to the rear springs. Variants (2.5i vs 3.6R, with/without roof accessories or towing packages) can also have different part specifications. Matching springs to the exact VIN/spec is the safe bet.

How can an owner tell if a coil spring has broken?
Common signs are a sudden drop in ride height at one corner, a sharp metallic clang over bumps, or a loose coil segment visible near the spring seat. Sometimes the break is small and hidden, a workshop can confirm by lifting the vehicle and inspecting the ends of each spring.

Will fitting lift springs affect warranty or handling?
Mild, compliant lift springs designed for the BS Outback can work well if matched with appropriate dampers and a proper alignment. However, altering ride height can change geometry, headlight aim, and ESC calibration. Owners should check local regulations and any remaining warranty terms before modifying.
