Parts for your 2014 Toyota Mark x-Suspension bushes

2014 Toyota Mark X Suspension Bushes

Suspension bushes are absolutely fitted to the 2014 Toyota Mark X (GRX130 series). Technical documentation such as the Toyota Repair Manual (TIS) and the Toyota Electronic Parts Catalogue (EPC) list multiple bushes across the platform: front lower control arm bushes in the double wishbone front end, rear multi‑link arm bushes, stabiliser bar (sway bar) bushes, and rear suspension member (subframe) bushes. These sources make it clear the Mark X relies on elastomer bushes to control geometry, isolate noise and vibration, and allow controlled movement at pivot points.

On the 2014 Mark X, bushes are the quiet achievers of the suspension. They sit at each control arm pivot, the sway bars, and the rear subframe, cushioning metal-to-metal contact and keeping the wheels tracking true. Their job is to soak up harshness, maintain alignment under braking and cornering, and let the arms articulate without clunks or play. When they age or split, the Mark X can start to wander on the motorway, tramline over ruts, chew out tyres, or thump over speed humps—none of which feels very Mark X.

Servicing-wise, it’s smart to have the bushes checked at regular intervals—think every 20,000–30,000 km or annually with your service, and always during a WOF/safety inspection. A technician will look for cracking, separation from the shell, oil swelling (from a leaky shock or engine oil), and excessive arm movement under a pry-bar.

• Common symptoms of worn bushes:
  • Steering shimmy or vague on-centre feel
  • Uneven or rapid tyre wear
  • Clunks on take-off, braking, or over bumps
  • Rear-end steer or instability on rough roads

Replacement is straightforward for a pro but can be involved. Many front and rear arm bushes press in/out, some arms come with bushes pre-installed. It’s best practice to torque suspension fasteners at normal ride height and book a four-wheel alignment straight after. On Aussie and Kiwi roads—heat, UV, and corrugations—quality rubber bushes keep NVH civilised, while polyurethane options can sharpen response at the cost of a firmer ride and a touch more noise. Genuine or reputable aftermarket kits both work, the key is correct fitment and alignment.

If the Mark X has done north of 120,000 km, or if the tyres are wearing oddly despite correct pressures, fresh bushes can be one of the best-value restorations—bringing back that planted, refined feel the GRX130 is known for.

Popular questions about 2014 Toyota Mark X suspension bushes

How often should the bushes be replaced on a 2014 Mark X?
There isn’t a strict time limit—bush life depends on kilometres, climate, and driving. Many last 100,000–160,000 km. Have them inspected at each service, replace when there’s cracking, separation, oil damage, or measurable play, or when alignment can’t be held.

What are the tell-tale signs the bushes are worn?
Look for vague steering, clunks over bumps, instability under braking, and uneven tyre wear. A technician may also spot displaced bush centres or arms that move excessively under load.

Are polyurethane bushes a good idea for daily driving?
They sharpen response and can last longer, but ride can be firmer with a bit more NVH. For a daily Mark X, high-quality rubber usually keeps the luxury feel, enthusiasts may prefer poly in sway bars or selected arms.
