Parts for your 2009 Subaru Forester-Coil springs

2009 Subaru Forester coil-springs — what they do and when to replace them

Coil springs are absolutely used on the 2009 Subaru Forester. Technical sources that confirm this include the Subaru Forester (SH, MY09) Factory Service Manual – Suspension section, Subaru FAST/parts catalogue for SH-series Forester front and rear springs, and major aftermarket catalogues (KYB and Monroe) that list front and rear coil springs for the 2009 Forester. These references specify a MacPherson strut with a coil spring up front, and a coil-over damper on the rear double-wishbone setup, so coil-springs are very much relevant to this model.

On a 2009 Forester, the coil-springs carry the vehicle’s weight, set ride height, and team up with the dampers (struts/shocks) to soak up bumps. They keep the tyres planted and the geometry in check so steering stays predictable. When a spring sags or snaps, ride height drops, handling goes sloppy, and you’ll often cop uneven tyre wear or clunks over corrugations. Rust pitting (common in coastal areas), broken pigtail ends, and uneven arch gaps left-to-right are classic giveaways.

As part of routine servicing, the coil-springs should be inspected at least every 20,000 km or annually. Look for chipped paint, corrosion, fractured coils, or a spring that’s not seated squarely in its isolator. If one spring is cactus, replace springs in axle pairs to keep the Forester sitting level. When springs are changed, it’s smart to fit new top mounts, bearings, dust boots and bump stops, then get a wheel alignment. If the vehicle tows or carries gear often, consider heavy-duty or raised-rate springs, but keep changes moderate to maintain damper control and stay road-legal.

• Tell-tales it’s time: rear end sag with a load, front-end dive, knocking over speed humps, uneven ride height, or visible cracks/rust.
• Best practice during replacement: use a quality spring compressor, mark orientation, torque control arm and mount bolts at normal ride height, replace in pairs, and finish with alignment.

DIY is doable with the right tools, but compressed springs store serious energy—if unsure, leave it to a pro. For Aussie and Kiwi owners, the 2009 Forester responds well to fresh, OE-spec or quality aftermarket coil-springs, restoring ride comfort, handling, and correct headlight aim after years of service.

Popular questions about 2009 Subaru Forester coil-springs

Do all 2009 Foresters have coil-springs front and rear?
Yes. The SH-series 2009 Forester runs a front MacPherson strut with a coil spring and a rear double-wishbone with a coil-over damper. Variants (X, XS, XT) may use different spring rates, but they’re all coil-sprung at both ends.

How long do the coil-springs typically last?
Many will go well past 150,000 km, but coastal corrosion, rough roads, and heavy loads can shorten life. Inspect at each service, replace if there’s sag, damage, or cracked paint exposing rust.

Can heavier or raised springs be fitted for towing or light off-road?
Yes, modest-rate or slightly raised springs are common. Pair them with suitable dampers and get an alignment. Keep lift sensible to maintain handling, braking, and legal compliance in AU/NZ.
