2017 Toyota Vitz/Yaris rack boots: what they do and when to replace them

Yes, rack boots are fitted to the 2017 Toyota Vitz/Yaris (XP130 series) because it uses a rack-and-pinion steering gear with electric power assist. Toyota’s Electronic Parts Catalogue for NSP130/NCP131 lists a “Boot, Steering Gear” on each side of the rack, and the Toyota workshop manual includes inspection and replacement steps for the boots in the Steering section. Those factory sources confirm the part is relevant on this model. If a boot splits, grit and water can reach the inner tie rod and rack bushes, so the boot is classed as a protective component rather than a pressure seal.

On the Vitz/Yaris, each rubber bellows boot keeps road splash, dust, and stones out while allowing the rack to travel freely. With EPS there’s no hydraulic fluid inside the boots, but they still keep grease around the inner tie rods and prevent corrosion on the rack bar. Left torn, moisture builds up and inner tie rods wear early. In New Zealand and Australia, a split rack boot is a common WOF/roadworthy defect, so it’s worth inspecting at every service or whenever the front suspension has been apart.

Drivers will usually spot trouble by:

• Visible cracks, tears, or loose clamps on the bellows.
• Grease sling on the inner guard or subframe near the rack ends.
• Play or knocking from the inner tie rod, especially over bumps.

If any of these show up, replace the damaged boot promptly and check the inner tie rod for free play. Boots are inexpensive, labour dominates because the outer tie rod end needs to be removed. Always get a proper wheel alignment afterwards, as toe can shift.

When fitting new boots, use quality clamps, orient the vent correctly, and avoid twisting the bellows as the rack moves lock-to-lock. Don’t pack the boot with extra grease – use only a light smear on the inner tie rod ball per the service manual. If the car sees a lot of dusty or coastal kilometres, consider inspecting the boots between scheduled services. Genuine or reputable aftermarket boots designed for the XP130 platform will fit best and last longer than generic items.

Do 2017 Toyota Vitz/Yaris models have rack boots?

They do. The XP130-series Vitz/Yaris uses an electric-assist rack-and-pinion steering gear, and Toyota’s EPC and workshop manual list a “Boot, Steering Gear” on each side. They’re essential to keep grime out of the inner tie rods and the rack bar.

How often should rack boots be replaced on a 2017 Vitz/Yaris?

There’s no fixed interval. Inspect them at each service and replace on condition if cracked, torn, or oil-soaked. In tougher use (gravel roads, coastal air), check more often. If a boot has failed, also assess the inner tie rod for wear.

Will replacing a rack boot affect wheel alignment?

Yes, it can. The outer tie rod end is usually removed to slide the old boot off, so toe can change. A post-repair wheel alignment is recommended to keep the car tracking straight and protect tyre life.
