Parts for your 2020 Mitsubishi Asx-Cv boots

2020 Mitsubishi ASX CV-boots: what they do and when to replace them

CV-boots are absolutely used on the 2020 Mitsubishi ASX. Technical references including the Mitsubishi Motors Workshop Manual for ASX/Outlander Sport/RVR (Front Axle – Drive Shaft and CV Joint sections, 2019–2021 coverage) and the Mitsubishi ASA Electronic Parts Catalogue list inner and outer CV boots for both 2WD and AWD variants. That means every 2020 ASX has front CV-boots, and AWD models have them on the rear drive shafts as well.

On this model, CV-boots are the flexible rubber bellows that cover the constant velocity (CV) joints on the drive shafts. Their job is simple but critical: they keep special moly grease in, and water, dust and road grit out. That lets the CV joints articulate smoothly while you steer and while the suspension moves, without wearing themselves out.

For everyday servicing of a 2020 ASX, a quick visual of the CV-boots should be part of the routine – think every service or roughly every 10,000–15,000 km. A good boot looks intact, pliable and dry on the outside, with clamps sitting tight at each end. A bad one has cracks, splits or loose clamps, and you’ll often spot grease flung around the inner wheel, strut or undertray. Left too long, a torn boot lets grit in and grease out, which can turn into clicking on full lock, shudder under load, and eventually a stuffed CV joint.

Replacing a damaged boot early saves the joint. The proper fix uses the correct CV-joint grease, new stainless clamps and a quality boot that matches the ASX’s joint size. Workshops will clean the joint, repack it and clamp the new boot to spec. If the joint has already worn (tell-tale clicking or rust-red grease), swapping the whole shaft assembly can be more economical than rebuilding the joint.

• Check at each service or WOF/RWC inspection for splits, weeping grease or perished rubber.
• Avoid blasting boots with solvent or high-pressure water – it accelerates cracking.
• If you hear clicks on turns, book it in fast, continued driving can escalate costs.
• AWD ASX owners: remember there are rear CV-boots too, so ask for a look over front and rear.

Look after the CV-boots and the ASX’s driveline stays quiet, smooth and drama-free for many kilometres.

Do all 2020 Mitsubishi ASX models have CV-boots?

Yes. All 2WD versions have CV-boots on the front drive shafts. AWD versions have them on both front and rear half-shafts. This layout is documented in Mitsubishi’s workshop manual and parts catalogue for the model.

How often should CV-boots be replaced on a 2020 ASX?

There’s no fixed time-based replacement. They’re replaced when damaged, perished or leaking. Have them inspected at every service or WOF/RWC. If a boot is split or a clamp is loose, replace it straight away to protect the CV joint.

What are common signs a CV-boot or joint needs attention on an ASX?

Grease spatter on the inside of the wheel or suspension, visible cracks in the boot, clicking or knocking on full lock, vibration on acceleration, or a burning grease smell after a drive. Any of these warrant a prompt inspection.
