Parts for your 2015 Mitsubishi Asx-Universal joints

2015 Mitsubishi ASX universal joints – are they actually used?

Short answer: universal joints aren’t a service item on a 2015 Mitsubishi ASX. Technical references including the Mitsubishi Motors Workshop Manual for GA1W/GA2W (ASX/RVR/Outlander Sport) and the Mitsubishi ASA electronic parts catalogue show two driveline layouts: the 2WD (GA1W) has front driveshafts with constant velocity (CV) joints and no propeller shaft at all, the AWD/4WD (GA2W) uses a two-piece propeller shaft with a centre bearing and CV-type joints at each end. The manuals specify the propeller shaft joints as sealed assemblies and “non-serviceable” — there are no replaceable cardan-style universal joints listed as separate parts.

That’s why a traditional universal joint isn’t relevant to this model. Mitsubishi chose CV joints on the ASX driveline for smoother torque delivery at larger operating angles and lower NVH, which suits a compact SUV with on-demand AWD. By keeping constant velocity through the prop shaft joints, driveline shudder and cyclic speed variation (a hallmark of cardan U-joints at angle) are reduced. On the 2WD ASX there’s simply no rear shaft, so there’s nowhere for a universal joint to live.

If the goal is to keep a 2015 ASX’s driveline in top nick, the sensible service focus is:

• For 2WD: inspect front CV boots and clamps, listen for clicking on lock, and check for grease sling.
• For AWD: check the propeller shaft centre bearing for play or rumble, inspect the CV-joint boots at each end of the shaft for splits or leaks, and check the rear diff and transfer case flanges for seepage. Any free play, vibration on overrun, or thumping on take-off warrants further inspection.

Because the ASX’s prop shaft joints are sealed and not designed for greasing, the workshop manual advises replacement of the complete propeller shaft assembly if a joint is worn or noisy, rather than pressing in a new universal joint. That parts-catalogue approach (complete assembly supply) is clearly shown in Mitsubishi ASA for GA2W propeller shaft listings.

If someone’s shopping for “universal joints” for a 2015 Mitsubishi ASX, the accurate match is either front CV joints/shafts (2WD and AWD) or the complete propeller shaft assembly (AWD). Asking for U-joints by name will usually lead to a dead end on this model.

Popular questions

Does my 2015 Mitsubishi ASX have universal joints?

On 2WD models, no — there’s no rear prop shaft. On AWD models, the propeller shaft uses sealed constant velocity joints rather than serviceable cardan-type universal joints. Mitsubishi’s GA1W/GA2W workshop manual and ASA parts catalogue show the joints as part of the complete shaft assembly.

Can the joints on the ASX prop shaft be greased or replaced individually?

They’re sealed-for-life CV joints, so there are no grease nipples. If a joint shows play, noise, or a split boot that’s leaked dry, the recommended fix per the Mitsubishi manual is to replace the propeller shaft assembly (and the centre bearing if needed). Some driveline specialists may recondition them, but it’s not a factory service procedure.

What symptoms point to driveline joint issues on a 2015 ASX?

Listen and feel for vibration at highway speed, a thump or shudder on take-off, rumbling that changes with road speed (centre bearing), or grease thrown around a joint area from a torn boot. Clicking on full lock is more typical of a front CV joint on the driveshafts. Any of these are a cue for inspection.
