Parts for your 2017 Toyota Rav4-Rack boots

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

Technical references including the Toyota Repair Manual for the XA40 RAV4 (2016–2018), the Toyota Electronic Parts Catalogue, and multiple OEM-equivalent parts catalogues confirm the 2017 Toyota RAV4 uses bellows-style steering rack boots on its electric rack-and-pinion steering gear. So yes—rack boots are fitted and they matter.

On the 2017 RAV4, the rack boots (also called bellows or gaiters) sit at each end of the steering rack, sealing the inner tie rods and rack bar from dust, water, and road grit. They keep grease in and contaminants out, which protects the rack’s sliding surfaces and the inner tie rod joints. Even though this RAV4 uses electric power steering (no hydraulic hoses or fluid), the boots are still critical, a split boot can let in grit that accelerates wear, causes play, and leads to premature rack or inner tie rod failure.

As part of routine servicing, rack boots deserve a quick look. A technician will scan for cracks, splits, loose or missing clamps, or grease weeping. Any damage means replacement—boots aren’t repair items. Because the boot has to slide freely through the steering range, even minor perishing can open into a full split under load.

• Common signs of trouble: visible tears, perished rubber, clicking or knock over bumps, uneven tyre wear, free play in the steering, or grease flung onto nearby components.
• Why act early: a ,30–,100 pair of boots and fresh clamps beats the cost of a steering rack or inner tie rods, plus an alignment.

Replacement is straightforward for a competent workshop. They’ll mark toe, remove the wheel, disconnect the outer tie rod, slide off the old boot and clamps, inspect and regrease the inner joint as required, fit the new boot with correct clamps, reassemble and finish with a wheel alignment. DIYers should note: don’t twist the boot, don’t reuse damaged clamps, and avoid nicking the new rubber on sharp threads. Because the RAV4’s EPS has no hydraulic fluid, finding oil inside a boot usually means old grease—not a power steering leak—but any contamination still warrants inspection.

Best practice for Aussie and Kiwi conditions: inspect every service, replace at the first sign of cracking, and always follow with a proper alignment to protect tyres and steering feel.

FAQs

Does the 2017 RAV4 have steering rack boots?

Yes. Technical documentation and parts catalogues list bellows-style boots on both ends of the electric rack-and-pinion steering gear. They seal the inner tie rods and keep the rack’s moving bits clean and lubricated.

How often should rack boots be replaced on a 2017 RAV4?

There’s no fixed kilometre interval—replace on condition. Have them inspected at every service. In harsh conditions (gravel, mud, coastal air), rubber ages faster, so be extra vigilant. If a boot is cracked, split, loose, or contaminated, replace it immediately and follow with a wheel alignment.

Can a split rack boot damage the steering rack?

It can. A torn boot lets grit and water into the inner tie rod and rack bar. That contamination can cause stiffness, play, or accelerated wear, potentially leading to inner tie rod or steering rack replacement—far pricier than a boot and clamps.
