Parts for your 2018 Honda Odyssey-Rack boots

2018 Honda Odyssey rack-boots: what they do and when to replace them

Based on Honda’s 2018 Odyssey service information for the Electric Power Steering (EPS) system and Honda’s electronic parts catalogue diagrams, the vehicle uses a rack-and-pinion steering gear with protective bellows on each side of the rack. These are commonly called rack boots (or steering rack bellows). Aftermarket catalogues for the 2018 Odyssey also list replacement rack-boot/bellows kits, confirming the part is fitted and serviceable on this model.

On the 2018 Honda Odyssey, the rack boots protect the inner tie rod joints and the ends of the steering rack from dust, water, and road grit while allowing full steering travel. They help keep grease where it should be and stop contaminants from chewing out the inner joints or the rack’s seals and bearings. Even though the Odyssey runs EPS (so there’s no hydraulic fluid at the rack), split boots can still let moisture in, and that can quickly turn into corrosion, noisy steering, or a loose, imprecise feel at the wheel.

There’s no strict time or kilometre interval to replace rack boots — they’re condition-based. As part of regular servicing, a visual check is smart. If the rubber shows cracks, feels hard, has obvious splits, or there’s grease flung around the inner guard, it’s time to sort it. Many techs recommend inspecting at every service and especially after rough-road or coastal driving.

• Common signs they’re due: visible tears or perishing, grease spray on the lower control arm or inner wheel well, dirt inside the boot, or a clunk from the inner tie rod.
• Why act quickly: a torn boot can let grit in and ruin the inner tie rod or the rack assembly — both far pricier than a boot kit.

Replacement is straightforward for a trained tech: the outer tie rod end is removed, the old clamps and boot come off, the rack groove is cleaned, and a new boot and proper clamp are fitted. The Odyssey’s EPS rack typically uses a breather/vent tube between the boots — that needs to be reconnected so pressure can equalise during steering. Cable ties aren’t the go, use the correct clamps so the boot seals properly without cutting into the rubber. After any work that disturbs the tie rod, a wheel alignment is recommended to keep tyre wear even and the steering tracking straight.

Tips for owners: keep an eye on the condition of the rubber during tyre rotations, stick with quality OEM-equivalent boots, and if a boot is torn on one side, consider doing both to keep wear even. A clean, intact rack boot is cheap insurance for the Odyssey’s steering rack and inner joints.

Popular questions about 2018 Honda Odyssey rack-boots

Do all 2018 Odyssey models have rack boots?
Yes. The 2018 Odyssey uses an electric power steering rack that still relies on rubber bellows (rack boots) on each side to keep contaminants out and grease in. They’re shown in Honda’s service and parts diagrams and are replaceable items.

How often should rack boots be replaced?
There’s no fixed interval. Check them at each service or around every 10,000–15,000 km. Replace them if they’re cracked, hardened, torn, or contaminated with grit or water. Acting early can prevent damage to the inner tie rods and rack.

Can rack boots be changed at home?
It’s possible for a competent DIYer with stands, the right tools, and the correct clamps. The outer tie rod end needs to come off, and care is needed to refit the breather tube and seat the boot without twisting. A wheel alignment after the job is strongly recommended.
