Parts for your 2018 Volvo Xc60-Universal joints

2018 Volvo XC60 universal joints – are they even a thing?

For the 2018 Volvo XC60, traditional cross‑type universal joints (U‑joints) aren’t fitted. Volvo’s SPA‑platform XC60 runs constant‑velocity (CV) joints throughout the driveline instead. That’s not just hearsay: the Volvo VIDA workshop information for the model year shows a two‑piece propeller shaft with CV joints at both ends and a centre support bearing, and the genuine Volvo parts catalogue lists the prop shaft as an assembly with CV joints, not U‑joints. The front and rear half‑shafts are Rzeppa‑type CV joints as well. Industry catalogues from GKN/Spidan and SKF likewise list CV components for the 2018 XC60 and no U‑joint applications. The AWD system uses a bevel/angle gear at the transaxle and a BorgWarner (Gen 5) coupling at the rear differential, both designed around CV‑type interfaces.

Why no universal joints? Modern Volvos chase low NVH (noise, vibration and harshness) and smooth torque delivery. CV joints maintain constant rotational speed through greater operating angles than a U‑joint and reduce vibration in the cabin. They also suit the packaging constraints of the angle gear and rear coupling, allowing compact flanged connections and better sealing. With sealed‑for‑life CV joints on the prop shaft and axle shafts, Volvo reduces routine maintenance points and potential water/dust ingress compared to greasable U‑joints.

What should owners and techs check instead of U‑joints? Focus on the bits Volvo actually fitted:

• CV joint boots on front and rear half‑shafts – look for splits, grease sling or clicking on full lock.
• Propeller shaft centre support bearing – inspect for play or rumbling on overrun.
• Prop shaft CV joints – check for backlash or vibration under load/at motorway speeds.
• Mounts and alignment – engine, transaxle and rear subframe mounts can also mimic driveline shake.
• Flange bolts and sealing – ensure prop shaft flanges are torqued correctly and angle gear/rear drive unit aren’t leaking.

Service tip: CV joints on the XC60 are typically non‑serviceable components, if a boot is torn or the joint is noisy, replacement of the affected shaft or prop shaft assembly is the correct repair as per VIDA procedures. Regular inspection at each service interval (or every 10,000–15,000 km) keeps on top of any wear before it turns into a big bill or an annoying vibration on a long Kiwi or Aussie road trip.

FAQs

Does a 2018 Volvo XC60 have universal joints?
No. The 2018 XC60 uses constant‑velocity joints on the front and rear drive shafts and at both ends of the propeller shaft. Workshop information and the OEM parts catalogue list CV joints, not cross‑type U‑joints.

If there’s no U‑joint, what usually causes driveline vibration?
Common culprits are worn prop shaft CV joints, a tired centre support bearing, damaged axle CV boots/joints, or perished engine/gearbox mounts. Tyre flat‑spotting, out‑of‑balance wheels, and rear coupling or angle‑gear issues can also show up as a shudder at specific speeds.

Is there routine maintenance for these joints?
They’re sealed units, so there’s no greasing. At each service, inspect CV boots for damage or grease spray, check the centre bearing and prop shaft joints for play, and confirm flange fasteners are snug. Replace the affected assembly if noise, clicking, or excessive backlash is present.
