Parts for your 2019 Mitsubishi Asx-Universal joints

2019 Mitsubishi ASX universal joints: what’s fitted and how to look after them

Based on the Mitsubishi ASX/RVR/Outlander Sport Workshop Manual (Propeller Shaft section) and the Mitsubishi ASA electronic parts catalogue, universal joints (Cardan joints) are fitted to AWD (GA2W) 2019 ASX models as part of the two-piece propeller shaft with a centre support bearing. Front‑wheel drive (2WD/GA1W) models don’t have a prop shaft at all, so there are no universal joints on those variants, they use constant‑velocity (CV) joints in the front drive shafts. Aftermarket catalogues back this up, listing complete prop shafts for AWD and no U‑joint listings for 2WD.

On AWD ASX models, the universal joints let the prop shaft transmit drive to the rear diff while the suspension and drivetrain move. Their job is to handle angle changes between the transfer output and the rear final drive without binding, keeping things smooth and quiet. When they wear, drivers often notice a clunk taking off, a rhythmic vibration at certain speeds, or a chirp/creak at low speed as the shaft rotates.

Most OEM ASX AWD prop shafts are supplied as a sealed assembly with staked, non‑greaseable U‑joints. That means there’s no periodic greasing, and if a joint is worn or seized, the factory repair is replacement of the complete propeller shaft. Some driveline specialists can rebuild and balance the shaft with serviceable joints, but that’s outside standard Mitsubishi procedures.

Good workshop practice during servicing includes:

• Inspecting for play at the U‑joints (any noticeable free movement or red dust at the caps is a red flag).
• Checking the centre bearing rubber for cracking or sag, and looking for flange bolt looseness.
• Road‑testing for vibrations on light throttle or decel that change with speed (often U‑joint or centre bearing related).
• Marking flanges before removal and refitting to preserve balance and orientation.

If replacement is needed, expect to swap the full shaft on most vehicles. It’s typically a straightforward remove‑and‑refit job, but alignment marks and correct torque on the flange bolts matter to avoid new vibrations. Keep an eye on underbody shields and heat guards going back exactly as they came off. As with any AWD driveline service, it’s smart to inspect rear diff and transfer case fluid condition while you’re there.

For 2WD ASX owners, universal joints simply aren’t part of the car. Any driveline knocks or vibrations at the front will relate to CV joints, engine/gearbox mounts, or tyres and wheels rather than U‑joints.

Popular questions

Does a 2019 Mitsubishi ASX 2WD have universal joints?
No. 2WD (front‑wheel drive) ASX models don’t have a propeller shaft, so there are no universal joints fitted. They use CV joints on the front drive shafts instead. Only AWD versions have a prop shaft with U‑joints.

Are the ASX AWD universal joints serviceable or greasable?
Factory prop shafts are usually sealed with staked, non‑greaseable U‑joints, so there’s no routine lubrication. If a joint fails, Mitsubishi’s workshop guidance is to replace the complete prop shaft. Some driveline specialists can rebuild the shaft with serviceable joints and then re‑balance it.

What are common signs the ASX’s universal joints need attention?
Listen and feel for a clunk on take‑off, a speed‑related vibration, or a chirping/squeaking noise at low speed. Underneath, look for rust‑coloured dust around the bearing caps, looseness at the joints, or a perished centre bearing support. Any of these warrant inspection before it develops into bigger driveline damage.
