2021 Mitsubishi Eclipse Cross rack-boots: what they do and when to replace them

Technical documentation confirms the 2021 Eclipse Cross runs an electric power–assisted rack‑and‑pinion steering gear that uses bellows-type rack-boots on both sides. Mitsubishi Motors workshop literature for Eclipse Cross (GK/GL platform, Steering Group) describes bellows sealing on the rack and inner tie-rod area, and OEM catalogues such as Mitsubishi ASA list steering gear bellows/dust boots for 2018–2023 Eclipse Cross models. Major aftermarket catalogues also carry direct-fit rack boots for this vehicle, backing up that they’re fitted from factory.

On this model, the rack-boots (also called bellows or gaiters) protect the rack bar and inner tie-rods from grit, water and road splash, while keeping the correct grease where it needs to be. Even though the power assist is electric, the steering is still a mechanical rack-and-pinion, and those boots are the frontline defence against premature wear. If a boot perishes or splits, contaminants can chew out the inner tie-rod socket and the rack seals, eventually turning a simple boot job into a steering rack replacement—no one wants that bill.

As part of regular servicing, it’s smart to check the rack-boots every 10,000–15,000 km or at each service interval. Look for cracks, oil or grease fling on the inside of the wheel, loose or broken clamps, or any stiffness or notching in steering after rain. If a boot is torn, replace it promptly. Best practice is to:

• Lift and support the car safely, remove the front wheel, and mark toe position before removing the outer tie-rod end.
• Slide off the old boot, clean the area, and apply the specified grease to the inner joint and rack bar contact surfaces.
• Fit quality replacement boots with proper band clamps (not cable ties), ensuring no twist and correct venting between sides.
• Refit, torque to spec from the service manual, and get a wheel alignment. If one boot has failed, inspect—and often replace—the other side too.

Genuine or OE-quality boots maintain fit and durability. Avoid turning the steering with the boot off, and don’t overpack with grease. Catch a dodgy boot early and the Eclipse Cross’s steering will stay light, precise and quiet for the long haul.

FAQs

Does the 2021 Eclipse Cross actually have rack-boots?
Yes. Workshop manuals for the GK/GL Eclipse Cross specify bellows on the steering gear, and both OEM and aftermarket parts catalogues list direct-fit rack boots for 2018–2023 models. That confirms they’re a standard, serviceable item.

How often should the rack-boots be checked?
Have them inspected at every routine service (roughly every 10,000–15,000 km). If you drive on unsealed roads or through floods, check sooner. Replace any boot that’s cracked, split, weeping or has loose clamps.

Can they keep driving with a torn rack-boot?
It’ll drive, but it’s risky. A torn boot lets water and grit into the inner tie-rod and rack seals, which can escalate to play, noise and costly rack damage. It’s far cheaper to replace the boot now and realign the front end than to wait.
