Parts for your 2020 Toyota C-hr-Rack boots

2020 Toyota C‑HR rack‑boots: purpose, checks and replacement

Based on technical sources including the Toyota C‑HR Repair Manual (Steering section) and the Toyota Electronic Parts Catalogue (Steering Gear & Link), the 2020 Toyota C‑HR uses a rack‑and‑pinion steering gear with bellows‑type rack‑boots (also called steering rack bellows) fitted over the inner tie rods. That makes rack‑boots absolutely relevant on this model.

On the C‑HR, those boots do a simple but vital job: they seal the ends of the steering rack, keeping dust, water, and road grit away from the rack bar and inner tie rod joints while helping retain grease on the moving parts. Even though the C‑HR uses electric power steering (so there’s no hydraulic fluid), the rack‑boots still matter because contamination will chew out the inner joints and can corrode the rack bar, leading to play, knocks and premature steering gear failure.

Tell‑tale signs a boot needs attention include visible cracks or splits, a missing or loose clamp, grease slung on the subframe, or a rubber boot that’s gone hard and brittle. A torn boot can let in mud and water after a big downpour or a gravel‑road run. Left too long, the inner tie rod may wear, you’ll get wandering or uneven tyre wear, and you could be up for a costly rack replacement.

As part of regular servicing in Australia and New Zealand, it’s smart to have the rack‑boots inspected every 12 months or 15,000 kilometres (whichever comes first), or at any WOF/rego safety check. Replace a boot at the first sign of damage—there’s no safe “she’ll be right” period once a boot is torn. Quality replacements should include new clamps, many techs also add a light smear of appropriate grease on the inner joint if specified by service data.

When replacing a boot, the outer tie rod end usually needs to come off, so having the front toe checked or a full wheel alignment done afterwards is recommended. On the C‑HR’s electric rack, don’t look for power steering fluid leaks—there aren’t any—but do keep an eye out for grime or water tracks near the boot area. Genuine or high‑quality aftermarket boots fitted correctly, clamped snugly, and checked at each service will keep the C‑HR’s steering tight and drama‑free for the long haul.

• Replace immediately if torn, cracked, or clamps are loose
• Inspect at every service or after off‑road/gravel driving
• Check wheel alignment after boot or inner tie rod work

Do 2020 Toyota C‑HRs have rack‑boots?

Yes. Factory documentation (Toyota C‑HR Repair Manual – Steering, Toyota EPC – Steering Gear & Link) shows bellows‑type rack‑boots fitted over the inner tie rods. They’re standard on the rack‑and‑pinion assembly used in this model.

How often should rack‑boots be checked or replaced?

Have them inspected at every scheduled service (about every 12 months/15,000 km). Replace any boot that’s split, perished, or has a loose/missing clamp. There’s no set time‑based replacement—condition is the decider.

Is it okay to drive with a torn rack‑boot?

It’s not recommended. A torn boot lets water and grit reach the inner tie rod and rack bar, which can quickly wear components and lead to expensive steering rack repairs. Book a replacement promptly and get the alignment checked afterwards.
