2021 Honda Odyssey rack boots: what they do and when to replace them

Technical sources confirm the 2021 Honda Odyssey does use rack boots, so they’re absolutely relevant on this model. Honda’s service manual (Honda eSM) for the RL6 Odyssey (2018–2023) shows bellows-style boots on both ends of the electric power steering rack, and the Honda Electronic Parts Catalogue lists a “Boot Set, Steering Gear” for 2021 models. Industry databases such as ALLDATA and Mitchell1 also include inspection and replacement procedures for these boots. So yes—rack boots are fitted to the 2021 Odyssey.

On this Odyssey, the rack boots (also called steering rack bellows) are the flexible accordion sleeves that seal the inner tie rods and the ends of the rack. Their job is simple but critical: keep water, road grit and dust out, and keep the inner joints and rack ends clean and protected. Even though the Odyssey runs electric power steering (no hydraulic fluid at the rack), contamination under a torn boot can still score the rack bar, wear the inner tie rod joints, and corrode components—leading to sloppy steering and costly repairs.

There’s no fixed replacement interval for rack boots. Instead, they should be checked at every service or alignment, and any time the front end has copped a hit (big potholes, kerbs) or after driving through floodwater or beach sand. If a boot is cracked, torn, split or the bands are loose, replace it straight away. Use quality boots that fit the rack and tie rod correctly, and always install new bands—don’t reuse old clamps or swap in hose clamps, as they can cut the rubber or fail to seal.

When replacing a boot, the outer tie rod end usually needs to come off. Note the tie rod length or count the turns so the toe setting is close on reassembly, then book an alignment to get it bang on. Seat the boot lips fully on the rack housing and inner tie rod, fit the specified bands, and make sure the bellows aren’t twisted at full lock. Avoid solvents on the rubber, and don’t pack the boot with grease—the inner joint is already lubricated. Kept intact, these little bellows quietly guard the Odyssey’s steering for years without any drama.

• What to watch for: splits or perishing, loose/missing bands, dirt or moisture inside the boot, new play in the steering, or uneven tyre wear.
• Pro tip: after any alignment or tie rod work, recheck that the boots aren’t wound up or rubbing.

Does the 2021 Honda Odyssey actually have rack boots?

Yes. Honda’s own service information (eSM) for the RL6 Odyssey shows boots fitted to each end of the electric steering rack, and the Honda EPC lists a genuine “Boot Set, Steering Gear” for this year. Trade databases like ALLDATA/Mitchell1 also document inspection and replacement. They’re standard equipment, not an add-on.

How often should rack boots be replaced or inspected?

There’s no set kilometre interval. Inspect them at every service and after any suspension or alignment work. If a boot is cracked, torn, perished or the bands are loose, replace it immediately. Catching a damaged boot early can save the steering rack and inner tie rods from gritty wear.

Is it OK to drive with a torn rack boot?

It’ll move, but it’s not wise. A torn boot lets water and road grit onto the rack and inner joint, which can quickly lead to corrosion, play in the steering and an expensive rack replacement. If a boot’s split, sort it promptly and have the alignment checked after the repair.
