2017 Toyota Vitz/Yaris steering rack: purpose, service tips and when to replace

According to Toyota’s New Car Features for the NSP130/NCP131 series and the Toyota Electronic Parts Catalogue (Group 44 – Steering Gear & Link), the 2017 Toyota Vitz/Yaris runs a rack‑and‑pinion steering rack with electric power steering (EPS). The Toyota Repair Manual also details zero‑point calibration procedures after steering work. So yes, a steering rack is absolutely fitted and relevant on the 2017 Toyota Vitz/Yaris.

This steering rack is the bit that translates the driver’s turn of the wheel into the front wheels pointing where they’re meant to go. The EPS motor provides assist, but the rack‑and‑pinion gear is the mechanical heart, tying the column to the road wheels via inner and outer tie‑rods. On the 2017 Vitz/Yaris, the assist is electric, so there’s no power‑steering fluid to top up. That means fewer leaks and less routine faff, but the rack, boots and tie‑rods still do the hard yards and need attention as the kilometres rack up.

For servicing, a workshop should check the rack boots (gaiters) for splits, inspect inner and outer tie‑rods for play, and confirm there’s no clunking, tight spots or notchy feel on centre. Any free play or uneven tyre wear can point to wear in the tie‑rod ends or the rack itself. A road test over bumps and a check on a hoist will usually tell the story. Because it’s EPS, technicians will also scan the EPS system for fault codes and verify the steering angle is calibrated.

If replacement is on the cards, using quality parts and fresh lock‑nuts is a must. After any rack or tie‑rod work, a precise wheel alignment is non‑negotiable, and the steering angle sensor zero‑point should be reset with a scan tool so the EPS knows straight‑ahead. Under the bonnet and underbody bolts should be torqued correctly, and the steering wheel centred to avoid a crooked wheel or EPS warning light. Daily drivers will appreciate the sharper feel, and tyres will thank them too.

• Tell‑tales that the 2017 Vitz/Yaris steering rack needs love: clunks over bumps, free play at the wheel, steering pull, uneven tyre wear, torn rack boots, or EPS warnings.
• Service tip: check the rack and tie‑rods every 15,000 km/12 months, avoid kerb hits, and rotate tyres to spot issues early.

Does the 2017 Toyota Vitz/Yaris have power steering fluid to change?

No. This model uses electric power steering, so there’s no hydraulic fluid service. Focus maintenance on rack boots, tie‑rods, alignment and an EPS scan for codes and steering angle calibration.

What symptoms suggest the 2017 Yaris steering rack or tie‑rods are worn?

Free play at the wheel, knocking over rough roads, tramlining, a steering wheel that won’t return smoothly, uneven inner/outer tyre wear, or a torn boot letting grit into the rack are common red flags.

After replacing tie‑rods or the rack, what’s essential before handing back the keys?

Perform a precise wheel alignment, centre the wheel, and carry out steering angle zero‑point calibration with a scan tool. A quick road test for straight tracking and no clunks seals the job.
