Parts for your 2016 Toyota Prius-Universal joints

2016 Toyota Prius — Are universal joints used?

For the 2016 Toyota Prius (XW50 series), universal joints (Cardan U‑joints) are not used in the driveline. Technical sources from Toyota’s service literature and parts catalogues identify the front axle shafts as constant‑velocity (CV) type: an inboard tripod CV joint and an outboard Rzeppa CV joint, paired with a front‑wheel‑drive transaxle. This layout eliminates the need for a propeller shaft and its associated U‑joints. Toyota’s New Car Features and Repair Manual sections covering “Front Drive Shaft Assembly” describe only CV joints and boots on this model. The Toyota electronic parts catalogue likewise lists no driveline U‑joint for the 2016 Prius.

Why the difference? SAE literature on joint design explains that a single Cardan universal joint transmits a non‑constant angular velocity when operating at an angle, which introduces vibration unless carefully paired and phased. Front‑wheel‑drive halfshafts in a Prius must articulate through large steering angles while keeping wheel speed uniform, that’s exactly what CV joints are designed to do. Hence, Toyota specifies CV joints at both ends of each front driveshaft for smoothness and efficiency.

It’s worth noting there is a separate universal joint in the steering intermediate shaft on many vehicles, including the Prius, to link the column to the rack. That steering U‑joint is not part of the driveline and is serviced only if symptoms (stiffness, knock, or play) appear, routine “universal‑joint” maintenance does not apply to the 2016 Prius driveline.

• Driveline layout: Front‑wheel drive transaxle, no prop shaft, no driveline U‑joints (Toyota Repair Manual/Parts Catalogue).
• Axle design: Inboard tripod CV and outboard Rzeppa CV joints specified for the front shafts (Toyota service information).
• Engineering basis: Single Cardan U‑joints create speed fluctuation at angle, CV joints maintain constant velocity through large angles (SAE technical guidance on joint behaviour).
• Market note: 2016 AU/NZ Prius is FWD only, later AWD‑e variants still avoid a prop shaft, so no rear U‑joints either.

If the focus is driveline service on a 2016 Prius, technicians should be inspecting CV boots and clamps for splits, leaks, or thrown grease at regular services. Universal‑joint replacement procedures are not relevant to this model’s driveline.

FAQs

Does a 2016 Toyota Prius have universal joints?
No, not in the driveline. The 2016 Prius uses CV joints on its front halfshafts and doesn’t have a prop shaft with U‑joints. There may be a universal joint in the steering intermediate shaft, which is unrelated to the axle/driveshaft system.

What joints are on the 2016 Prius front axles?
Each front driveshaft uses an inboard tripod‑type CV joint and an outboard Rzeppa‑type CV joint. They’re chosen to handle large steering angles while keeping wheel speed smooth and vibration low. Service focuses on checking CV boots and grease, not U‑joints.

Could a clunk or stiffness be a steering U‑joint on a Prius?
Possibly. If there’s a notchiness or play felt through the wheel, the steering intermediate shaft U‑joint could be worn. It’s replaced as an assembly when faulty, it isn’t on a periodic maintenance schedule like some rear‑drive U‑joints.
