Parts for your 2017 Toyota Mark x-Suspension bushes

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

Suspension bushes are absolutely used on the 2017 Toyota Mark X (GRX130 series). Toyota’s New Car Features for the GRX130 confirms a front double-wishbone and rear multi-link layout, both of which rely on multiple rubber bushes to control arm movement and isolate vibration. The Toyota Repair Manual sections for Front and Rear Suspension detail bushing inspection and replacement procedures, and the Toyota Electronic Parts Catalogue lists individual arm bushes, stabiliser bar bushes and subframe/differential mount bushes for this model year. So yes — suspension-bushes are very much relevant on this car.

On the Mark X, these rubber (and in some positions, fluid-filled) bushes sit where control arms, sway bars and the rear subframe mount to the chassis. Their job is to keep alignment steady under braking and cornering, soak up harshness, and stop metal-to-metal contact. When they age, the rubber cracks or softens, causing clunks, vague steering, rear-end shimmy, brake shudder, and uneven tyre wear.

As part of routine servicing, a workshop should visually inspect all suspension-bushes every 20,000 km or 12 months, looking for splits, oil contamination, torn sleeves, or weeping from hydro-bushes. Pay close attention to the front lower control arm rear bushes and the rear multi-link bushes, as these typically work hardest on Aussie and Kiwi roads with corrugations and potholes.

Replacement is straightforward for a qualified tech: some bushes can be pressed in and out, while others may be better done by fitting a complete arm assembly. Always torque bushing bolts at normal ride height to avoid pre-loading the rubber, and book a four-wheel alignment immediately after. Where Toyota specifies replacement fasteners or one-time-use nuts, they should be renewed.

For ride quality closest to factory, quality OEM-equivalent rubber bushes are the go. Polyurethane can sharpen response but often increases noise and vibration. While in there, it’s smart to check sway bar links, ball joints and rear subframe mounts, as wear in one spot often masks problems elsewhere.

Owners who notice wandering under braking, a knock over speed bumps, or accelerated inner-edge tyre wear should have the Mark X inspected promptly. Fresh bushes bring back that planted, quiet feel the GRX130 chassis is known for.

Popular questions about 2017 Toyota Mark X suspension-bushes

Do all 2017 Mark X models have suspension bushes?
Yes. Per Toyota’s New Car Features and the Repair Manual for the GRX130, every 2017 Mark X uses multiple rubber bushes in the front double-wishbone and rear multi-link assemblies, plus stabiliser bar and subframe/diff mounts.

How long do the bushes typically last?
It varies with driving and climate. Many see 80,000–150,000 km, but rough roads, heavy loads and fluid leaks can shorten life. Including a bush inspection at each service helps catch cracking or play before it affects tyres and handling.

Can just one bush be replaced, or is a whole arm needed?
Both options exist. Some positions have serviceable press-in bushes, others are more practical as complete arms. Workshops often choose complete arms if the original bush is bonded or if ball joints are tired, then follow up with a wheel alignment.
