2017 Toyota Mark X suspension bushes — what they do and when to replace them

Based on Toyota technical literature — including the Toyota Mark X (GRX13#) Repair Manual, Toyota New Car Features (NCF) and the Toyota Electronic Parts Catalogue — the 2017 Toyota Mark X runs a double-wishbone front and multi-link rear setup that relies on multiple rubber suspension bushes throughout the control arms, subframe mounts and stabiliser bar links. So yes, suspension bushes are absolutely used on this model and are a key wear item worth keeping an eye on.

On the 2017 Mark X, suspension bushes are the quiet achievers. Pressed into arms and links, they isolate noise and vibration, keep alignment steady under brakes and cornering, and let the geometry move the way Toyota intended. When they’re healthy, the car tracks straight, turns crisply and rides smoothly over Aussie and Kiwi roads. When they’re tired, drivers might notice vague steering, clunks on bumps, feathered tyres and braking that doesn’t feel as planted.

As part of routine servicing, it’s smart to inspect bushes every 20,000–30,000 kilometres or annually if the car sees rough surfaces, coastal exposure or lots of stop‑start. Look for cracked or perished rubber, torn voids, displaced sleeves or weeping from hydro-bush types. A lever test can show excess movement, but final calls are best made on the hoist by a qualified tech.

• Replace in axle pairs where practical to keep handling balanced.
• Always perform a four-wheel alignment after bush replacement.
• Torque all pivot bolts at normal ride height to avoid preloading the new bushes.
• Check related parts at the same time: ball joints, tie rod ends, sway bar links and tyres.
• OE-style rubber bushes keep factory comfort and NVH low, polyurethane can feel sharper but may add noise and require periodic lubrication.

There’s no fixed expiry date — many Mark X bushes last well past 100,000 kilometres — but heat, age and potholes take their toll. If the steering wheel fights on camber changes, there’s a dull thud over speed humps, or inside shoulders of the front tyres scrub out, it’s time for a closer look. Getting on top of worn bushes early protects tyres, shortens braking distances and brings back that tidy, confident feel the Mark X is known for.

Popular questions about 2017 Toyota Mark X suspension bushes

How long do the factory bushes typically last?

In normal Australian and New Zealand driving, many factory rubber bushes see 80,000–150,000 kilometres. Cars doing lots of city kerb hits, gravel, or towing can need them earlier. Age matters too — a low‑kilometre example that’s a decade old can show perishing even if it hasn’t travelled far.

What are the classic symptoms of worn Mark X bushes?

Tell‑tales include clunks on take‑off or over speed humps, steering wander, shimmy under braking, uneven tyre wear (especially inner edges) and a general loss of turn‑in precision. Visual checks may reveal cracked rubber or off‑centre sleeves in the control arm bushes.

Should they go for OEM rubber or polyurethane replacements?

OEM-style rubber is the safe bet for daily use — quiet, compliant and true to Toyota’s tune. Polyurethane can sharpen response and reduce deflection, which some drivers like, but it may increase NVH and can need occasional grease. If the Mark X is a daily commuter, quality rubber is usually the right call.
