2012 Toyota Vitz/Yaris Steering Rack — What It Does and How to Look After It

Per Toyota’s technical documentation for the XP130 series (2011–2013) — including the Toyota Repair Manual, New Car Features and the Toyota Electronic Parts Catalogue — the 2012 Toyota Vitz/Yaris uses a rack-and-pinion steering gear (steering rack) with electric power steering (EPS) assistance at the steering column. So yes, a steering rack is fitted on this vehicle.

The steering rack converts the driver’s steering wheel input into side-to-side movement that turns the front wheels. On the 2012 Vitz/Yaris, assistance comes from an electric motor on the steering column, not hydraulics, which means no power steering fluid to check. The rack itself remains a precise mechanical link between the wheel and the tyres, with inner and outer tie-rod ends setting and holding toe alignment.

As part of regular servicing, it pays to give the steering rack a once-over. A quick look under the front reveals rubber rack boots (gaiters) that keep grease in and grit out. If those boots split, water and road grime can chew through inner tie-rod joints and the rack bar. Catching that early saves a lot of coin.

• What to watch for:
  • Free play, vague steering or tramlining
  • Clunks or knocks over bumps when turning
  • Uneven or accelerated tyre wear
  • Torn rack boots or grease flung around the inner wheel area
  • Steering off-centre after hitting a pothole or kerb

Service tips for Aussie and Kiwi owners: at each service or WOF/rego check, inspect the rack boots, inner and outer tie-rod ends and the lower steering shaft for play. There’s no fluid to top up on this EPS system, but alignment matters — get a proper four-wheel alignment if you replace tyres, notice pull, or after any front-end work.

If the rack or inner tie rods need replacing, go for quality OEM or reputable remanufactured parts. Many jobs require lowering the front subframe slightly, torque all fasteners to spec, renew single-use hardware where required, and always finish with an alignment. Because the EPS motor lives on the column, swapping the rack usually doesn’t involve EPS motor replacement, but after alignment it’s smart to perform steering angle neutral/zero-point calibration if your Yaris/Vitz is equipped with VSC/ESC — a quick scan-tool procedure most workshops can do.

With gentle city use and good boots, the rack can last well over 200,000 km. Regular inspections, sorting any play early, and keeping the alignment bang-on will keep the little Toyota pointing straight and steering sweet.

Does the 2012 Vitz/Yaris use power steering fluid?

No. It runs electric power steering (EPS) with assistance on the column, so there’s no hydraulic fluid or pump. If you spot oily residue near the rack, it’s usually engine oil, trans fluid, or grease escaping from a torn rack boot — not power steering fluid.

Do I need an alignment after replacing tie rods or the steering rack?

Absolutely. Any time inner or outer tie rods or the rack come off, toe setting is disturbed. A proper four-wheel alignment is essential to avoid uneven tyre wear and off-centre steering, and it helps EPS/VSC systems behave as intended.

How long should a steering rack last on a 2012 Yaris/Vitz?

With intact rack boots and decent roads, many see well beyond 200,000 km. Premature wear often traces back to torn boots, frequent kerb strikes, or neglected alignment. Regular inspections during routine servicing will catch issues before they get spendy.
