Parts for your 2017 Toyota Rav4-Rack boots

2017 Toyota RAV4 rack boots — what they do and when to replace them

Based on Toyota technical literature for the XA40-series RAV4 (2016–2018) — specifically the Steering: Steering Gear section of the Toyota Repair Manual and the Toyota Electronic Parts Catalogue (EPC) listing “Boot, Steering Gear” — the 2017 Toyota RAV4 uses a rack-and-pinion electric power steering (EPS) assembly with protective bellows on each end. Those bellows are commonly called rack boots, and they’re absolutely fitted and relevant on this model.

On a 2017 RAV4, rack boots seal the inner ends of the steering rack and the inner tie-rod joints from water, mud, and road grit. They also help retain lubricant where it’s needed and allow the rack to move freely without ingesting contaminants. Because the RAV4 runs EPS (not hydraulic power steering), there’s no fluid inside the rack boots — but the boots still play a crucial role in protecting the inner tie rods and the rack’s seals and bearings. A torn or perished boot lets in debris that can quickly wear the joint, create free play at the wheel, and in a worst case shorten the life of the steering rack, which is a pricier fix than a simple boot.

For routine servicing, it’s smart for workshops to inspect rack boots at every service interval (typically 10,000–15,000 km or 12 months), and after any off-road use, deep-water crossings, or kerb strikes. Look for splits, perishing, loose or missing clamps, grease sling on the inner guard, or moisture and dirt tracked under the boot. Any damage is a replace-now item — cracked boots don’t get better with time.

Replacement is straightforward for a trained tech: the outer tie-rod end is removed, the old boot and clamps are taken off, the new boot is slid into place and secured with proper clamps, then the tie-rod end is refitted to the recorded length. Because even careful work can nudge toe settings, a wheel alignment afterwards is recommended. Go for OE or OE-quality thermoplastic boots and proper stainless clamps rather than cable ties, cheap, thin rubber tends to split early in Aussie and Kiwi heat. If the inner tie rod shows wear or play, it’s sensible to replace that at the same time.

• Tell-tale signs: steering wander or clunks, uneven tyre wear, or visible splits/grease around the inner tie rod area.
• Service tip: don’t jack under the rack, keep splash shields in place, and have boots rechecked after suspension lifts that alter tie-rod angles.

FAQs

Does the 2017 RAV4 actually have rack boots?
Yes. Toyota’s Repair Manual for the XA40 RAV4 and the Toyota EPC list protective bellows (“Boot, Steering Gear”) on both ends of the EPS rack. They shield the inner tie-rod joints and rack internals from dust, water and grit.

How often should rack boots be checked or replaced?
They should be inspected at every routine service or at least annually, and after off-road trips or deep-water crossings. Replace immediately if cracked, split, loose, or oil/grease contaminated. There’s no fixed kilometre lifespan — condition is the guide.

Do rack boots require a wheel alignment after replacement?
It’s best practice to get an alignment. Even when the tie-rod end is refitted to the same measured length, minor variations can alter toe, which affects tyre wear and steering feel.
