Parts for your 2020 Toyota C-hr-Rack boots

2020 Toyota C‑HR rack boots: what they do and how to look after them

Rack boots are fitted to the 2020 Toyota C‑HR. Technical references including the Toyota C‑HR Repair Manual (Steering — Electric Power Steering — Steering Gear) and the Toyota Electronic Parts Catalogue for 2017–2021 C‑HR (e.g., NGX10/ZYX10 platforms) show an electric rack‑and‑pinion steering gear with bellows‑type rubber gaiters (steering rack boots) on both sides to protect the inner tie rods and rack. New Zealand’s NZTA VIRM (WoF) also lists split or missing steering rack gaiters as a rejection item, underscoring their presence and safety importance on this model.

On the 2020 Toyota C‑HR, the rack boots are those concertina‑style rubber sleeves sitting on either end of the electric steering rack. Their job is simple but critical: keep grease in and water, grit and road grime out. By sealing the inner tie rod joints and the exposed section of the rack, they help the electric power steering stay smooth and consistent, prevent corrosion, and save the inner joints from premature wear. When a boot perishes, splits or loses a clamp, contaminants quickly work their way in, and that can turn a cheap rubber part into a spendy steering repair.

There’s no hard‑and‑fast replacement interval, instead, they should be inspected at every service (typically every 10,000–15,000 km or annually in AU/NZ conditions). Look for fine cracking in the folds, oil or grease flung onto the subframe or wheel, or moisture and dirt tracking inside the boot. If the C‑HR has seen lots of gravel road work, kerb knocks, or deep puddles, be extra diligent with checks. In NZ, a split rack boot can fail a Warrant of Fitness, so catching it early avoids a hassle.

When replacement’s needed, quality matters. Genuine or reputable aftermarket boots with heat‑resistant rubber and proper clamps are the go. It’s wise to replace boots in pairs if they’re the same age. After fitting, a wheel alignment isn’t usually required for a boot‑only job, but if an inner tie rod also needs attention, book an alignment to keep tyre wear even. Fresh grease where specified, correct clamp tension, and ensuring the boot isn’t twisted at full lock will keep the new parts happy.

• Watch for: visible splits, grease spray near the wheel, notchy steering feel, or a WoF inspection note.
• Service tips: inspect at every service, use proper clamps (not cable ties), and check inner/outer tie rods for play while you’re there.

Popular questions about 2020 Toyota C‑HR rack boots

Does the 2020 Toyota C‑HR have rack boots?
Yes. The C‑HR runs electric power‑assisted rack‑and‑pinion steering, and each side of the rack has a bellows‑style rubber boot protecting the inner tie rod and rack from dust, water and grit. They’re a small, inexpensive component that do big work keeping the steering smooth.

How often should rack boots be replaced on a 2020 C‑HR?
There’s no set kilometre interval. In Australia and New Zealand, it’s best practice to inspect them at every service and replace only if they’re cracked, perished, loose, or split. Many last years, but harsh sun, gravel roads and deep water can shorten their life. In NZ, a damaged boot can cause a WoF fail.

Can someone drive a C‑HR with a split rack boot?
It’ll usually still drive, but it’s not a good idea. A torn boot lets in water and grit that can rapidly wear the inner tie rod and corrode the rack. That can turn a quick boot swap into a bigger steering repair, and in NZ it can’t pass a WoF while damaged.
