Parts for your 2019 Toyota Mark x-Steering bushes

2019 Toyota Mark X steering-bushes: what they do and when to replace them

Based on Toyota technical documentation, steering-bushes are absolutely relevant to the 2019 Toyota Mark X (GRX130). The Toyota Electronic Parts Catalogue for the GRX130 series lists steering gear mounting cushions/insulators and clamps that secure the rack to the front subframe, and the Toyota Repair Manual Steering section details inspection and replacement procedures for these insulators and column bushes. That means the 2019 Mark X does use steering-bushes.

On this model, the steering-bushes are rubber insulators that mount the rack-and-pinion assembly to the crossmember and isolate the steering column. They keep the rack centred, damp road vibration, and stop metal-on-metal harshness. With electric power steering on late GRX130s, these bushes also help maintain precise steering feel without the whine or slack you’d expect if things were loose.

When they age, the rubber can compress, crack, or oil-soak, which shows up as vague steering, a clunk over bumps, or the car tram-tracking on rutted roads. If the wheel needs small constant correction on the motorway or there’s a dull knock felt through the column, the bushes could be tired.

During servicing of a 2019 Toyota Mark X, it’s smart to inspect the rack mounts and column bush at around 60,000–80,000 km, or sooner if the vehicle sees rough roads. Look for perished rubber, torn lips, or movement of the rack when a helper rocks the steering wheel. Also check for oil contamination from nearby leaks, as petroleum can prematurely soften rubber.

Replacement is straightforward for a pro: the rack is supported, brackets are removed, old insulators are pressed out, and new bushes are oriented correctly then torqued to spec. It’s best practice to replace bushes as a set and finish with a wheel alignment to make sure toe is spot on. On EPS-equipped racks, the battery should be disconnected and the steering kept centred, some workshops perform a steering angle reset after reassembly.

As for parts choice, quality OE-style rubber keeps the factory refinement, while reputable polyurethane options can sharpen response at the expense of a touch more road feel. Either way, fresh steering-bushes bring the Mark X back to the crisp, quiet steering it’s known for.

• Common signs of wear: clunking over bumps, vague on-centre feel, wandering, shimmy under braking, visible cracks in the bush.
• Tips: avoid contaminating new bushes with oils, recheck fastener torque after a short run, and always book an alignment.

Popular questions about 2019 Toyota Mark X steering-bushes

Does the 2019 Mark X have steering rack bushes or a solid mount?
Yes, it uses rubber insulator bushes to mount the rack to the front subframe. These cushions control movement and noise while keeping the rack accurately located for consistent steering feel, especially with the electric power steering setup.

How can someone tell if their steering-bushes are worn?
Listen and feel for a dull clunk over small bumps, a wandering sensation on the motorway, or extra play when rocking the steering at standstill. A technician can watch the rack while the wheel is turned, if the housing shifts in the mounts or the rubber shows cracking or separation, they’re due.

Do you need a wheel alignment after replacing steering-bushes?
Yes. Even if the tie rods weren’t disturbed, removing and refitting the rack mounts can nudge toe settings. A post-repair alignment ensures the Mark X tracks straight and protects tyre life.
