Parts for your 2021 Mitsubishi Asx-Cv joint

2021 Mitsubishi ASX CV Joint — Purpose, Care and Replacement Guidance

Referencing technical sources, the 2021 Mitsubishi ASX is fitted with CV joints and they’re absolutely relevant to the driveline. Mitsubishi Motors’ ASX/RVR/Outlander Sport Service Manual (Group 26: Front Axle, late-2010s through 2021 revisions) details the front drive shafts using an inner tripod (plunge) joint and an outer Rzeppa-type constant velocity joint. The Mitsubishi ASA electronic parts catalogue lists the front drive shaft assemblies, outer CV joints and boot kits for this model year. Independent service publishers (e.g., Haynes for ASX/RVR 2010–on) also cover CV joint inspection and axle replacement procedures. That makes the CV joint a core service item on the 2021 ASX.

On the ASX, the CV joint’s job is to send power from the transaxle to the wheels smoothly while the suspension moves and the wheels steer. The outer joint handles the big steering angles at the front hubs, while the inner joint slides in and out to cope with suspension travel. Because the joints are packed with high-moly grease and sealed by flexible boots, they run quietly and efficiently when everything’s intact.

For everyday servicing in Australia and New Zealand, it’s smart to ask for a CV boot check at each 12‑month/15,000 km service. Look for split or perished rubber, loose clamps, or grease flung around the inside of the wheel or under the guard. Coastal salt air, gravel roads and heat can age boots faster, so a quick visual once in a while pays off.

If a boot is torn but the joint isn’t clicking, a boot replacement and fresh grease can save the day. If there’s a repetitive clicking on tight turns, a shudder on take‑off, or vibration under load, the joint may be worn and the best fix is usually a reconditioned or new driveshaft assembly. During replacement, use the correct hub‑nut and driveshaft torque per the factory spec, keep the splines and grease pristine, and reseat the circlip properly. If the strut-to-knuckle bolts were loosened, a wheel alignment check is worthwhile.

Owners who tow, tackle corrugations, or rack up big urban kilometres should keep an ear out for CV noises and book an inspection early. Sorting a weeping boot now is far cheaper than replacing a noisy joint later, and keeps the ASX driving smooth and drama‑free.

• Watch for: clicking on turns, grease spray near the wheel, vibration on acceleration.
• Service tip: inspect CV boots every service, replace boots early to preserve the joint.
• Repair note: prefer complete shaft assemblies for speed and reliability if the joint is noisy.

Popular questions about 2021 Mitsubishi ASX CV joints

How long do CV joints last on a 2021 ASX?
With intact boots, many last well beyond 150,000 km. Heat, gravel, and torn boots shorten life. Regular inspections and early boot replacement dramatically extend service life.

What are the classic symptoms of a failing CV joint?
A rhythmic clicking or clacking on tight turns points to the outer joint. Grease splatter on the inner rim or guard suggests a split boot. Shudder or vibration under load can indicate inner joint wear or other driveline issues.

Can the boot be replaced without changing the whole shaft?
Yes—if caught early and the joint is still quiet and smooth. Once there’s clicking or visible pitting/play, replacing the complete shaft assembly is usually faster, cleaner, and more reliable.
