Parts for your 2018 Subaru Forester-Sway bars & links

2018 Subaru Forester sway-bars-&-links — what they do and when to service them

Referencing technical sources, this model absolutely uses sway-bars-&-links. The Subaru Service Manual for the 2018 Forester (SJ) lists both Front Suspension — Stabiliser System and Rear Suspension — Stabiliser System, and the Subaru Genuine Parts Catalogue shows front and rear stabiliser bars with link assemblies for all 2018 Forester variants. Subaru’s Technical Information System (STIS) likewise details inspection and replacement procedures for the stabiliser bar, D-bushes and end links.

On the 2018 Subaru Forester, the stabiliser (sway) bars tie the left and right suspension together to control body roll. The links connect the bar to the strut or control arm, letting the bar twist only when the car leans. The result is flatter cornering, better tyre contact, and more confidence in crosswinds, sudden lane changes and on winding Kiwi and Aussie roads.

Because the Forester has relatively compliant suspension travel for comfort and light off‑road use, the sway bars and links do a lot of balancing work. The links use ball joints and the bar rides in rubber (or polyurethane) D‑bushes, over time, joints loosen and bushes can perish, squeak or split.

• Common signs they’re due: clunks or knocks over small bumps, squeaks on roll, a loose or wandering feel in quick direction changes, and visible torn link boots or cracked D‑bushes. Feathered tyre edges can also hint at excess roll.
• Inspection tip: check for play at each service or every 15,000 km, pay extra attention after beach driving, corrugations or towing, which can accelerate wear.

When servicing sway-bars-&-links on a 2018 Forester, replace worn links or D‑bushes promptly to keep handling sharp. It’s smart to replace links in pairs (left and right) and match D‑bush size to the bar diameter. Tighten link and bracket fasteners with the vehicle at normal ride height to avoid preloading the bushes. An alignment generally isn’t required for sway bar work, but if other suspension components have been disturbed, get one done. In coastal Australia and New Zealand, surface rust on link studs is common — a dab of anti‑seize on clean threads helps future servicing. After any replacement, road‑test over bumps and recheck fastener torque.

If noises persist after renewal, have the workshop check strut top mounts and control arm bushes, as they can mimic sway bar symptoms.

• How long do sway bar links and bushes last on a 2018 Forester?
  In typical Aussie and Kiwi conditions, they often last 60,000–120,000 kilometres. Rough roads, corrugations and coastal salt can shorten that, so regular inspection is the best guide.
• Can it be driven with worn sway bar links?
  Usually, yes for short distances, but expect more body roll and less precise steering. For safety and tyre life, sort them sooner rather than later.
• Should both sides be replaced?
  Yes — replacing links and D‑bushes in pairs keeps handling balanced and helps the new parts last longer.
