2012 Toyota Vitz/Yaris Steering Bushes

Based on Toyota’s workshop literature for the XP130-series Vitz/Yaris (NCP131/NSP130/KSP130) with column-assist electric power steering (EPS), and the Toyota Electronic Parts Catalog (EPC) illustrations for the rack-and-pinion mounting, this model uses steering rack mounting bushes (also called rack mount or cushion bushes). These are rubber isolators that secure the steering rack to the front subframe. Their presence is also reflected in reputable aftermarket catalogues that list replacement rack-mount bush kits for 2011–2019 Yaris/Vitz. So, steering bushes are fitted and relevant for the 2012 Toyota Vitz/Yaris.

On this Vitz/Yaris, the steering bushes are small but crucial. They clamp the rack-and-pinion to the subframe and soak up vibration so the cabin stays quiet while the front wheels track straight. With column-assist EPS, the electric motor is in the steering column, so solid, healthy rack bushes are key to keeping the rack precisely located, that’s what preserves toe angles and on-centre feel.

What they do day-to-day is simple: reduce harshness, stop the rack moving around under cornering and braking loads, and keep the steering geometry where it should be. When they start to perish, the driver will often notice a light knock over sharp bumps, a vague or wandering feel on the motorway, or slight tramlining. Uneven front tyre wear and a steering wheel that doesn’t feel as crisp off centre can also point to tired bushes.

There’s no fixed replacement interval from Toyota, but as a rule of thumb they’re worth inspecting every 60,000–100,000 kilometres, or whenever the front end is apart for suspension work. Cars seeing rough roads, heavy kerbing, or fluid contamination (engine oil or coolant can swell rubber) may need them earlier.

Replacement is straightforward for a trained tech: support the subframe as needed, remove the rack clamps, swap the bushes, then torque the hardware to spec from the Toyota repair manual. If Toyota specifies new bolts or clamps for this job, use them. A wheel alignment afterwards is strongly recommended, because even small changes in rack position can nudge toe out of spec.

Owners can choose OE-style rubber for comfort or quality polyurethane for a firmer, more direct feel. Poly bushes sharpen response but may add a touch more NVH—great for keen drivers, less ideal if comfort is the priority. Don’t lubricate rubber with petroleum products, if needed, use a silicone-based assembly lube approved for the material.

• Common signs they’re due: clunks over bumps, vague steering, uneven tyre wear.
• Good practice: inspect during WOF/roadworthy checks and after any front-end knock.
• Post-replacement: book a four-wheel alignment.

Popular questions

Does the 2012 Yaris/Vitz use power steering fluid?
It uses column-assist electric power steering (EPS), so there’s no hydraulic power steering pump, hoses, or fluid to service. If you’re seeing oily residue near the rack, it’s likely engine or gearbox oil, not power steering fluid—worth checking because contamination can prematurely age the rack bushes.

How long do steering rack bushes typically last on a 2012 Yaris/Vitz?
Many will run well past 100,000 km, but life varies with road conditions and driving style. City kerbs, speed bumps and gravel roads speed up wear. Include them in routine inspections, replace at the first signs of cracking, softening, or rack movement under load and get an alignment done after.

Can worn steering bushes cause a WOF/roadworthy fail?
Yes. Excessive play or visible deterioration in the rack mounts can be flagged during WOF/roadworthy checks. Symptoms like steering knock, wandering, or uneven tyre wear can also trigger a closer look. Replacing the bushes restores proper rack location and steering precision, helping the vehicle pass.
