Parts for your 2018 Mitsubishi Eclipse cross-Cv boots

2018 Mitsubishi Eclipse Cross CV Boots — Purpose, Care and Replacement

CV boots are absolutely fitted to the 2018 Mitsubishi Eclipse Cross. The model uses front driveshafts with constant‑velocity (CV) joints, and on S‑AWC all‑wheel‑drive variants there are rear driveshafts as well. Technical references that show this include the Mitsubishi Motors Eclipse Cross Workshop Manual (GK1W/GK9W), Group 26 – Front Axle and Group 27 – Rear Axle, which detail outer Rzeppa and inner tripod joints covered by thermoplastic boots, plus inspection and replacement procedures, and the Mitsubishi ASA electronic parts catalogue, which lists front and rear CV joint boot kits for 2018 model codes. So, CV boots are relevant service items on this vehicle.

Those flexible boots are there to keep the joint’s moly grease in and dust, water and road grit out. When intact, they let the joint articulate smoothly as the wheels steer and the suspension moves, so there’s no binding or clunks on take‑off. A split boot, though, quickly flings grease across the inner guard and lets contamination chew out the joint needles and races. Leave it long enough and the joint will click on turns or vibrate under load, and you’ll be up for a complete shaft.

For Aussie and Kiwi servicing, it’s wise to check CV boots at every routine service interval (about every 10,000–15,000 km or 6–12 months, depending on your schedule and usage). A quick torch-light inspection of the bellows and clamps is usually enough. In coastal or unsealed-road use, step up the frequency—salt spray and dust are hard on rubber and clamps.

What to look for:

• Grease sling around the inner rim or undertray.
• Fine cracking on the bellows, especially at fold roots.
• Loose, missing or corroded clamps.
• Boot swollen, hard, or gone soft from contamination.

If damage is found early and the joint hasn’t gone gritty, a boot-only replacement with fresh grease and new stainless clamps is fine. If there’s play, clicking, or rusty paste in the joint, go the whole driveshaft. After any boot work, the technician should confirm clamp tension, re‑centre the boot to avoid twist, and road‑test for noise. Rotating tyres regularly and keeping undertrays fitted will also extend boot life on an Eclipse Cross.

How often should CV boots be inspected on a 2018 Eclipse Cross?

Have them checked at each routine service—typically every 10,000–15,000 km or 6–12 months. If the vehicle sees beach runs, gravel, or lots of rain and mud, inspect more frequently as grit and salt speed up deterioration.

What are the signs a CV boot has failed?

Grease spray on the inner guard or undertray, visible splits or cracking in the bellows, or a loose clamp are the early clues. If the joint starts clicking on turns or buzzing under acceleration, the damage has likely progressed beyond a boot.

Is it better to replace just the boot or the whole shaft?

If the tear is caught early and the joint isn’t contaminated, a boot kit with fresh grease is cost‑effective. If there’s play, noise, metal paste, or water ingress, replacing the complete driveshaft is the safer long‑term fix.
