Parts for your 2017 Toyota Wish-Steering bushes

2017 Toyota Wish steering bushes — what they do and when to service them

Based on Toyota’s ZGE20-series Wish repair literature and parts catalogues for the 2017 model year, this vehicle uses an electric power steering rack mounted to the front subframe with isolator bushes, along with column support bushings. That means “steering bushes” are absolutely relevant on a 2017 Toyota Wish, they’re serviceable items that influence steering feel, alignment stability and noise, vibration and harshness (NVH).

On this Wish, the rack-and-pinion assembly is bolted to the crossmember via rubber bushes that cushion the rack, control movement under load and help keep the steering geometry true. Over time, rubber hardens, cracks or compresses, allowing the rack to shift slightly. That’s when drivers start noticing vague on-centre feel, a clunk over potholes, or a bit of wander on the motorway. Because the steering is EPS, there’s no hydraulic fluid at the rack, but oil contamination from engine or gearbox mist can still degrade the rubber.

As part of regular servicing, it’s smart to visually check the steering rack bushes every 20,000–30,000 km, or once a year if the Wish sees rough roads. Look for cracking, separation from the sleeve, ovalised holes, shiny rub marks, and any oil-swollen rubber. With the front end safely raised, a gentle pry on the rack housing while watching for excess movement can tell a lot. Any knock when rocking the steering left-right with the wheels on the ground is also a clue.

• Common symptoms: clunks over sharp bumps, tramlining or drift, uneven or fast tyre wear, and a steering wheel that won’t self-centre cleanly.
• Good practice: after bush replacement, carry out a proper wheel alignment and reset steering angle if required.

Replacement is straightforward workshop work but does require safe support of the subframe and correct torque on the rack fasteners. Genuine-style rubber bushes maintain factory NVH and feel, high-quality polyurethane options can sharpen response and last longer but may pass a bit more road texture into the cabin. If there’s play at the inner tie rods or the column lower joint, tackle those at the same time—there’s not much point fitting fresh bushes around tired joints.

There’s no fixed kilometre interval for replacement, because climate and use vary across Australia and New Zealand. As a rule of thumb, a 2017 Wish that’s city-driven and serviced regularly will often keep its original bushes for well past 100,000 km, while vehicles that work on coarse-chip or corrugated roads may need them earlier. Keeping oils off the bushes, checking them at each service, and aligning the car after any steering work will keep the Wish pointing straight and feeling tight.

FAQs

Does a 2017 Toyota Wish actually have steering bushes?
Yes. The ZGE20-series Wish uses an EPS rack mounted to the front subframe with rubber isolator bushes, and the steering column uses support bushings. These components control rack movement and help manage NVH, so they’re an important part of the steering system.

How long do steering rack bushes last on a Wish in Australia or New Zealand?
There’s no set interval, but many last beyond 100,000 km in urban use. Cars that see coarse-chip or unsealed roads may need them sooner. Annual inspections are wise, with replacement recommended if cracks, deformation or excess rack movement are found.

Should the bushes be upgraded to polyurethane?
Polyurethane can sharpen steering feel and resist ageing better than rubber, which some owners like. The trade-off is a touch more NVH. For factory ride and refinement, stick with quality OEM-style rubber, for a sportier feel and durability, polyurethane is a sensible option.
