Parts for your 2009 Toyota Mark x-Steering bushes

2009 Toyota Mark X steering bushes — what they do and when to replace them

Based on technical references, steering bushes are fitted to the 2009 Toyota Mark X (GRX130 series). The Toyota service literature (TIS/Repair Manual, Steering section) shows the rack-and-pinion steering gear mounted to the front subframe with rubber bushes, and the Toyota Electronic Parts Catalogue lists dedicated “bush, steering gear” components for this model. So yes — steering bushes are relevant on a 2009 Mark X.

On this Mark X, the steering bushes cushion and locate the steering rack on the subframe. They soak up vibration and harshness from rough Kiwi and Aussie roads, keep the rack square to the column and tie-rods, and help maintain sharp on-centre feel. When the rubber ages, heat and oil exposure can harden or swell the bushes, allowing the rack to shift under load. That usually shows up as a vague or wandering feel, a clunk over bumps, or inconsistent toe that can scuff the tyres.

As part of regular servicing, it’s smart to have the steering bushes inspected whenever the front end is up — say every 20,000–30,000 km or annually. A tech will look for cracking, perishing, soft or oil-soaked rubber, and any rack movement while the wheels are rocked side to side. If power steering fluid has leaked in the past, the rubber can degrade faster.

• Common signs they’re due: knock/clunk from the rack area, tramlining or wander, vague steering, uneven inner/outer tyre wear, and steering pull under acceleration or braking.
• Best practice on replacement: renew bushes as a set, torque all fasteners with the vehicle at ride height, and book a wheel alignment straight after.
• Parts choice: genuine-style rubber keeps the factory refinement, quality polyurethane can sharpen response but may add a touch more road feel and noise.

When replacing, the subframe or rack may need to be supported and slightly lowered for access. It’s a straightforward job for a workshop familiar with Toyota FR platforms. After installation, ensure the steering wheel is centred and, if equipped, the steering angle sensor is calibrated so stability control behaves properly. Given the Mark X’s balanced chassis, fresh bushes can make it feel tight and confident again without spending a fortune.

Popular questions about 2009 Toyota Mark X steering bushes

Do 2009 Mark X models actually have steering rack bushes?
Yes. Toyota’s GRX130 Mark X uses a rack-and-pinion steering gear mounted to the subframe with rubber bushes. Both the Toyota Repair Manual (TIS) and the Toyota EPC list these bushings for the model year.

How long do the steering bushes last?
There’s no fixed interval — many last well past 100,000 km, but heat, fluid leaks and rough roads can shorten that. If there’s play, clunks or tyre wear that won’t align out, it’s time to check and likely replace them.

Rubber or polyurethane — which is better?
For daily use on Aussie and Kiwi roads, fresh OEM-style rubber keeps the quiet, comfy feel. Polyurethane can sharpen steering and resist oil better, which some drivers love, but it can add a touch more vibration and road texture through the wheel.
