Parts for your 2018 Mitsubishi Eclipse cross-Universal joints

2018 Mitsubishi Eclipse Cross universal joints — are they used?

Short answer: universal joints aren’t a thing on the 2018 Mitsubishi Eclipse Cross. The driveline uses constant velocity (CV) joints rather than the old-school cross-and-bearing (U‑joint) setup. That’s backed by factory literature: the Mitsubishi Motors Eclipse Cross (GK) Service Manual for 2018MY lists CV joints on the front halfshafts (Group 26, Front Axle) and describes a maintenance‑free propeller shaft for S‑AWC models (Group 27A, Propeller Shaft) without any greaseable U‑joints. The Mitsubishi parts catalogue (ASA/EPC) also shows complete halfshafts with CV joints and a propeller shaft assembly, with no separate U‑joint service parts.

Why no U‑joints? The Eclipse Cross is a front‑drive‑based SUV. On 2WD variants there’s no rear driveshaft at all, so there’s nowhere for a universal joint to live. On S‑AWC AWD models, Mitsubishi engineered the propeller shaft with constant velocity style joints to cut vibration and lash, and to handle larger operating angles smoothly. CVs are quieter and deliver steadier rotational speed than a cross‑type U‑joint, which helps with refinement and traction control logic.

What should owners look after instead? For everyday servicing, a tech will keep an eye on CV boots for splits or grease sling, listen for clicking on full lock (classic CV noise), and check the prop shaft centre bearing and mounts on AWD cars if there’s a shudder. Fluids in the transfer/differential units should be changed on schedule, and any driveline vibration under load should be diagnosed early before it snowballs into a bigger repair. If a joint on the prop shaft does fail, it’s typically replaced as a complete shaft assembly per Mitsubishi’s guidance.

• 2WD models: front CV halfshafts only, no U‑joints.
• S‑AWC AWD models: prop shaft with CV‑type joints, no serviceable U‑joints.
• Service focus: CV boots, centre bearing, mounts, and driveline fluids.

Popular questions

Does the 2018 Eclipse Cross have universal joints?

No. 2WD models don’t have a rear prop shaft, and AWD S‑AWC models use CV‑type joints in the propeller shaft rather than traditional U‑joints. There are no grease nipples or separate U‑joint kits listed by Mitsubishi for this model.

What symptoms feel like a bad U‑joint on an Eclipse Cross?

If there’s a driveline shudder, clunk on take‑up, or a hum that changes with speed, it’s more likely a worn CV joint, a tired prop shaft centre bearing (AWD), or a mount rather than a U‑joint. Clicking on full steering lock points to a front CV. A workshop can pinpoint it quickly on a hoist.

What should be serviced instead of U‑joints on this vehicle?

Have the CV boots inspected at each service, check the prop shaft centre bearing and coupling hardware on AWD cars, and replace transfer and rear diff oils as scheduled. Address any vibration early to avoid damage to the shaft or bearings.
