Parts for your 2018 Mitsubishi Asx-Cv boots

2018 Mitsubishi ASX CV-boots: what they do, why they matter, and how to look after them

CV-boots are absolutely relevant to the 2018 Mitsubishi ASX. Mitsubishi’s ASX/RVR Workshop Manual for the GA1W/GA2W platform (Front Axle and Driveshaft sections) and the Mitsubishi ASA electronic parts catalogue both show inner and outer constant velocity (CV) joints on the front driveshafts, each protected by rubber boots. On AWD variants, the rear halfshafts also use CV joints and boots. You’ll also find multiple aftermarket parts catalogues listing ASX CV-boot kits for model years around 2018, confirming fitment.

On the ASX, the CV-boot is the flexible rubber (or TPE) sleeve that seals the CV joint, keeping the special moly grease in and water, sand, and road crud out. That sealed grease is what lets the joint articulate smoothly through steering and suspension travel without grinding itself to pieces. A healthy boot keeps the joint quiet, the steering feel tidy, and the driveline reliable.

When a boot cracks, splits, or its clamp loosens, grease gets flung onto the inner guards and suspension, and contaminants work their way into the joint. Left too long, the CV joint starts clicking on turns, then vibrates under load, and can eventually fail—turning a simple boot job into a full driveshaft or joint replacement.

• Tell-tale signs: grease spray inside the wheel or on the control arms, visible cracks in the boot, a metallic clicking on tight turns, or a vibration on acceleration.

As part of routine servicing on a 2018 ASX, it’s smart to inspect all CV-boots every 10,000–15,000 km (or at each oil service). If the vehicle sees gravel roads, beach launches, or lots of wet weather, check them more often. Wipe the boots clean and look closely for hairline cracks, perishing near the folds, loose or missing clamps, or fresh grease. For AWD models, don’t forget the rear halfshafts.

If a boot is perished, split, or the clamp has let go, replace the boot immediately and re-pack the joint with the correct CV moly grease. Quality boot kits include new clamps and grease—use those rather than reusing old hardware. A technician will remove the shaft, clean and inspect the joint, re-grease, fit the new boot, and torque everything to spec. Many workshops recommend replacing boots in pairs on the same axle for consistency.

A torn CV-boot is a common reason for a WOF failure in New Zealand and can knock you back on an Aussie roadworthy, so staying on top of this small part saves cash and hassle down the track.

FAQs

How often should the CV-boots on a 2018 Mitsubishi ASX be replaced?

There isn’t a fixed replacement interval—boots are replaced on condition. Inspect them at every service (around 10,000–15,000 km). If a boot shows cracking, is leaking grease, or a clamp is loose, replace it straight away to protect the CV joint.

Can someone drive a 2018 ASX with a torn CV-boot?

It’s not recommended. A small split quickly flings grease out and lets water and grit in. That can damage the CV joint within a few drives, leading to clicking noises on turns and costly repairs. If a tear is spotted, organise a boot replacement as soon as possible.

Do AWD ASX models have more CV-boots than FWD versions?

Yes. All ASX models have CV-boots on the front driveshafts. AWD versions add rear halfshafts, each with inner and outer CV joints and boots, so there’s more to inspect and maintain on those vehicles.
