Parts for your 2017 Toyota Crown-Universal joints

Are universal joints used on the 2017 Toyota Crown?

Short answer: no—traditional cross-type universal joints aren’t fitted to the 2017 Toyota Crown’s factory driveline. Technical references that cover the S210-series Crown (2012–2018)—including Toyota’s Repair Manual (Driveline/Axle – Propeller Shaft section) and the Toyota Electronic Parts Catalogue for the S210—show the Crown uses a two‑piece propeller shaft with a flexible coupling (often called a guibo) at the transmission end and a constant velocity (CV) joint at the differential end, supported by a centre bearing. There’s no serviceable cross‑type U‑joint listed for this application. This layout is also consistent with contemporary Toyota/Lexus rear‑drive platform literature and Aisin driveline NVH guidance that favours CV joints and flex couplings for refinement.

Why does the Crown skip universal joints? It’s mainly about smoothness, noise and vibration control, and long-term reliability with minimal servicing. A CV joint maintains near-constant rotational speed through angle changes, which reduces torsional fluctuation and driveline shudder. The flexible coupling helps isolate engine and road vibrations before they’re transmitted through the cabin—particularly valuable on premium sedans and the Crown Hybrid where quietness is a design priority. Toyota’s use of these components also enables a largely maintenance-free prop shaft assembly under normal operating conditions.

For owners chasing a knock, hum, or vibration under load, it’s worth checking the parts the Crown actually uses instead of hunting for a U‑joint:

• Flexible coupling: look for surface cracks, separation, or perished rubber.
• CV joint and boot: inspect for split boots, grease sling, or play at the rear flange.
• Centre support bearing: check the bearing and rubber hanger for wear or sagging.
• Propeller shaft alignment/angles: ensure correct installation after gearbox, diff, or mount work.

Servicing typically involves visual checks during scheduled maintenance, listening for changes in noise, and addressing any seepage or boot damage promptly. If the CV joint or flex disc is worn, Toyota specifies replacement of the affected component or, in some cases, the entire propeller shaft assembly. As always, follow the Toyota repair manual procedures and torque specs, and re-check driveline balance and flange alignment marks during reassembly.

• Does a 2017 Toyota Crown have universal joints?
  Despite being rear‑wheel drive, the 2017 Crown doesn’t use traditional cross‑type U‑joints. It’s built with a flexible coupling at the transmission end and a CV joint at the differential end, plus a centre support bearing. That setup delivers better NVH performance than old‑school U‑joints.
• What causes driveline vibration on a Crown if there are no U‑joints?
  Common culprits are a cracked or perished flex disc, a worn CV joint or split boot (losing grease), a tired centre support bearing, or misalignment after driveline or mount work. Tyre/wheel issues and differential mounts can also add to the shake.
• Can the CV joint or flex disc be serviced, or do they need replacement?
  The flex disc and CV joint are generally replaced when worn or damaged. The joint itself isn’t usually rebuilt in routine service, if the boot is split but the joint isn’t noisy or rough, a prompt boot replacement may save it. Follow Toyota’s parts and procedures for the S210 Crown.
