Parts for your 2014 Toyota Mark x-Steering bushes

2014 Toyota Mark X Steering Bushes

Steering bushes are absolutely relevant to the 2014 Toyota Mark X. Technical references including Toyota’s Electronic Service Manual (ESM) for the GRX130 series (ST—Steering, Rack and Pinion) and the Toyota Electronic Parts Catalogue (EPC) show the steering rack mounted to the front crossmember via rubber cushions/bushes and brackets. These isolator bushes are serviceable components designed to control rack movement and reduce noise, vibration and harshness.

On this model, the steering bushes sit between the rack housing and the subframe, acting like small shock absorbers. They keep the rack located precisely, so the wheel’s inputs translate cleanly to the tyres without the rack shifting about. That means a tighter, more confident feel on turn-in, better feedback through the wheel, and fewer knocks over broken roads. They also cut down on vibration buzzing into the cabin, which is why fresh bushes can make a car feel younger.

As part of routine servicing, it’s smart to check the steering bushes every 20,000–30,000 km or if there are complaints about vague steering. Oil contamination, heat and age harden the rubber, leading to cracking or compression set. A quick inspection on a hoist with a pry bar can reveal excessive rack movement. If the rack shifts or you can see torn rubber, they’re due.

Typical signs they’re worn include:

• Clunks or thuds from the front when taking off, braking or hitting potholes
• Steering that feels loose on centre or wanders at motorway speeds
• Vibration or kickback in the wheel over corrugations
• Visible cracking, deformation or oil-swell of the bushes

Replacement is straightforward for a workshop: support the rack, remove the bracket bolts, swap the bushes, and torque the hardware correctly. Because the rack position can shift slightly, a post-repair wheel alignment is recommended even if the tie rods weren’t touched. Most owners stick with genuine-style rubber for comfort, while enthusiasts sometimes opt for quality polyurethane to sharpen response. If going poly, expect a firmer feel and make sure the kit includes the correct sleeves and lubricant to avoid squeaks.

Keeping steering bushes in good nick preserves that planted, rear-drive Mark X balance. It’s an affordable fix that pays off every time the road turns twisty.

Popular questions about 2014 Toyota Mark X steering bushes

Do all 2014 Mark X models actually have steering rack bushes?
Yes. The GRX130-series rack-and-pinion is mounted to the subframe using rubber isolator bushes and clamps. Whether the car has hydraulic or electric assist, the rack still relies on those bushes to control movement and filter vibration.

How often should steering bushes be replaced?
There’s no fixed interval, it depends on kilometres, road conditions and contamination. They’re typically inspected at each service. Many last well past 100,000 km, but cars driven on rough roads or with oil leaks nearby may need them earlier. Replace when cracked, soft, deformed or if the rack can be moved by hand with the brackets fitted.

Will changing steering bushes affect alignment?
The tie rods aren’t disturbed during a basic bush swap, but the rack’s resting position can change slightly. A quick alignment check after replacement is a good idea to confirm toe is still on spec and the steering wheel is straight.
