Parts for your 2004 Toyota Mark x-Steering bushes

2004 Toyota Mark X Steering Bushes

Based on Toyota’s technical literature for the GRX120/121 platform (2004 Toyota Mark X), including the Steering section of the factory repair manual and the Toyota Electronic Parts Catalogue diagrams for “Steering Gear & Link,” this model uses a rack-and-pinion steering gear mounted to the front subframe with rubber isolator cushions. Those cushions are commonly called steering bushes. So yes—steering bushes are relevant and fitted to the 2004 Toyota Mark X.

On this Mark X, the steering bushes sit between the steering rack housing and the crossmember. Their job is to keep the rack located precisely while soaking up vibration and road harshness. When healthy, they help the steering feel tight and direct without sending every bump through the wheel. Over time, heat, age, and especially power-steering fluid leaks can soften or crack the rubber. Once the bushes deform, the rack can shift slightly under load, which shows up as vague on-centre feel, a dull clunk when turning or hitting sharp bumps, and a steering wheel that doesn’t feel as confidence-inspiring.

As part of routine servicing in Australia and New Zealand conditions, it’s smart to have the steering bushes checked every 10,000–15,000 km or at least once a year. A technician will look for cracks, separation, ovaling of the bush, and oil-soaked rubber. If the vehicle’s had a steering fluid leak, prioritise inspection—the fluid can prematurely age the bush material.

• Common signs they’re due: clunking over driveway entries, steering that wanders or “tramlines,” kickback on rough roads, and uneven tyre wear that isn’t solved by alignment alone.
• Replacement options: OEM-style rubber for factory feel, or quality polyurethane (e.g., reputable aftermarket brands popular in AU/NZ) for a firmer, more precise response.
• Service tips: address any power-steering leaks before fitting new bushes, ensure the rack mounts and bolts are clean and torqued correctly, and book a wheel alignment check afterwards.

In most cases, steering bush replacement is a straightforward, rack-in-car job: the rack is supported, old cushions are removed, new bushes are pressed or slid into place, and hardware is torqued to spec. If noises remain after replacement, have the tie-rod ends, lower control arm bushes, and sway bar links assessed, as they can mimic similar symptoms.

Looked after properly, fresh steering bushes restore that planted, composed steering feel the Mark X is known for, making daily commuting and long open-road runs feel tidy and predictable.

Popular questions about 2004 Toyota Mark X steering bushes

Does the 2004 Mark X actually have steering bushes?
Yes. The factory repair manual and Toyota EPC for the GRX120/121 show rubber isolator cushions mounting the steering rack to the subframe. Those are the steering bushes, and they’re serviceable.

What are the symptoms of worn steering rack bushes on a 2004 Mark X?
Drivers often notice a clunk over sharp bumps, vague or wandering steering on the motorway, and kickback through the wheel on rough chipseal. You may also see uneven tyre wear and a slight delay between steering input and vehicle response.

How often should the steering bushes be replaced?
There’s no fixed interval, as lifespan depends on kilometres, road conditions, and fluid exposure. Have them inspected at regular services, many owners see good life past 100,000 km, but any cracking, oil-soaking, or obvious rack movement under load is reason to replace sooner.
