Parts for your 2018 Subaru Exiga-Suspension bushes

2018 Subaru Exiga suspension-bushes — what they do and when to replace them

Suspension-bushes absolutely are relevant to the 2018 Subaru Exiga (commonly sold as the Exiga Crossover 7). Technical references including the Subaru Service Manual for the Exiga/Exiga Crossover 7 (Front Suspension FS and Rear Suspension RS sections) and the Subaru FAST electronic parts catalogue list multiple bushings: front lower control arm bushes, front and rear stabiliser (sway bar) bushes, rear lateral link and trailing arm bushes, and rear subframe bushes. Aftermarket catalogues for AU/NZ also range replacement bushes for this model, confirming they’re fitted from factory.

On the Exiga, these rubber or hydraulic bushings separate metal suspension parts, letting the arms pivot smoothly while soaking up vibration and road shock. They set the alignment under load, keep the wagon tracking straight, and take the edge off bumps so the seven-seater stays comfy and quiet.

As part of normal servicing, it’s smart to have the suspension-bushes visually checked every 20,000 km or 12 months, or sooner if the car tows, carries a full crew, or lives on coarse chip. Look for cracking, splitting, torn sleeves, oil weep from hydro-bushes, or bushes that are visibly deformed in their housings. After any bush replacement, a four-wheel alignment is a must on the Exiga’s multi-link rear to avoid tyre scrub.

• Common symptoms: clunks over speed humps, vague steering, shudder under braking, inside-edge tyre wear, or a “tramlining” feel on rutted roads.
• Priority items: front lower control arm rear bushes and front/rear sway bar bushes tend to wear first, rear lateral link bushes follow on higher-km cars.
• Replacement approach: individual bushes can be pressed in/out with the right tools, many workshops prefer complete arms for speed and longevity.
• Lifespan: often 80,000–150,000 km depending on roads and loading, Aussie heat and Kiwi coarse chip can shorten that.

When upgrading, quality OEM-equivalent rubber keeps the family-friendly ride, firmer polyurethane tightens steering but can add a bit of road feel. Torque all pivot bolts at normal ride height to avoid pre-loading the bushes. Keep an ear out after storms or gravel drives—if the Exiga starts creaking or drifting, it’s time to get those bushes checked.

Popular questions about 2018 Subaru Exiga suspension-bushes

How do you know the Exiga’s bushes need replacing?
Owners usually notice clunks over potholes, wandering on the motorway, or uneven tyre wear. A technician can lever-test the arms and inspect for splits, perishing, or fluid seep from hydro-bushes. If alignment won’t hold between services, that’s another tell-tale.

Do you need an alignment after bush replacement?
Yes. Any time control arm, lateral link, or trailing arm bushes are changed, the geometry shifts. A proper four-wheel alignment on the Exiga’s multi-link rear keeps tyre wear even and restores straight-line stability.

Rubber or polyurethane bushes for the Exiga?
Rubber (OEM-style) preserves the factory ride and noise levels—great for family use. Polyurethane sharpens response and can last longer, but may transmit a bit more vibration. Many owners mix: rubber in arms, poly in sway bar mounts for a neat handling lift.
