Parts for your 2008 Subaru Forester-Coil springs

2008 Subaru Forester coil springs — what they do and when to replace them

Coil springs are absolutely relevant and fitted to the 2008 Subaru Forester. Subaru’s factory service manuals for the late SG series (up to MY08) and the launch-year SH series (introduced during 2008) detail coil-sprung suspension at both ends. The front uses a MacPherson strut with a coil spring, while the rear is a strut-and-coil setup on SG, and a double-wishbone with separate coil spring and shock on SH. Subaru parts catalogues and independent workshop references (like Haynes/Max Ellery) list front and rear coil spring part numbers across these models, confirming their use.

On this Forester, the coil springs carry the vehicle’s weight, set ride height, and let the dampers control bounce. They’re the unsung heroes behind comfort, grip, and load-carrying—whether it’s a school run or a gravel track to the bach. Good springs keep the tyres planted, steering consistent, and the headlights level, tired springs lead to sag, uneven tyre wear, and a crashy ride.

For servicing, they’re not a regular “replace by kilometres” item, but they should be inspected at every service. In Aussie and Kiwi conditions—coastal air, corrugations, and the odd unsealed shortcut—look for corrosion, chipped paint, fractured coils, and shiny “binding” marks. Measure ride height side-to-side, a droop on one corner points to a weakening spring. If towing, running a roof pod, or loading up for holidays, consider heavy-duty or raised-rate springs matched to quality dampers.

• Replace in axle pairs to keep handling balanced.
• Always use a proper spring compressor—stored energy is no joke under the bonnet or in the shed.
• Fit new top mounts/insulators if they’re perished or noisy while you’re in there.
• After any spring change, book a wheel alignment, camber and toe will shift, especially on SH’s multi-link rear.
• If the car sits low, bottoms out over speed humps, or shows cupped tyre wear, it’s time to act.

Typical lifespan varies with use, but many Foresters see 150,000–200,000 km before springs show enough sag or corrosion to justify replacement. Go for reputable brands or genuine-spec replacements, mixing random rates can upset stability control and ride comfort. A fresh, correctly rated set will bring back that planted, tidy Forester feel Aussies and Kiwis expect.

Popular questions

How long do 2008 Forester coil springs usually last?

With normal city and highway driving, many last 150,000–200,000 km. Beach runs, gravel roads, or carrying heavy loads can shorten that. The best guide is condition: check for rust, cracks, and sagging ride height.

Do I need a wheel alignment after replacing coil springs?

Yes. Changing ride height alters suspension geometry. An alignment helps prevent uneven tyre wear and keeps the steering tracking straight, especially important on the SH model’s multi-link rear end.

Can I replace just one coil spring?

It’s not recommended. Springs settle with age, replacing in pairs on the same axle keeps the vehicle level and handling consistent under brakes and through corners.
