Parts for your 2019 Toyota Prius-Universal joints

2019 Toyota Prius universal joints — are they even a thing?

Short answer: universal joints aren’t used in the driveline of the 2019 Toyota Prius. According to Toyota’s New Car Features (NCF) for the ZVW5# series and the 2019 Prius Repair Manual on Toyota’s Service Information (TIS), the Prius runs a transverse transaxle with front half‑shafts that use constant velocity (CV) joints — inboard tripod-type and outboard Rzeppa-type — rather than traditional tailshaft universal joints.

On front‑wheel‑drive models, power goes straight from the hybrid transaxle to the front wheels via those CV shafts. That layout removes the need for a long propeller shaft and the U‑joints you’d find on a rear‑wheel‑drive ute or 4x4. The Repair Manual’s front drive shaft section shows service of CV boots and joints, not U‑joints, which lines up with what technicians see on the hoist.

If the car is an AWD‑e (Toyota also calls it E‑Four in some markets), the rear wheels are driven by an independent rear motor‑generator unit mounted on the rear axle with a built‑in reduction gear. There’s no prop shaft running down the centre of the car, so again — no universal joints to service. This is spelled out in the NCF description of the AWD‑e layout, which highlights the standalone rear drive module.

So for anyone hunting “2019 Toyota Prius universal joints” as a service item: they’re not part of the driveline. What actually needs an eye during servicing are the CV joints and their rubber boots — split boots fling grease, dry the joint, and can lead to clicking on full lock. A decent service centre will also check front wheel bearings, tyre condition, and alignment if there’s any vibration or noise.

Worth noting: the steering column typically uses a small universal joint on the intermediate shaft, but that’s a steering component, not a driveline tailshaft U‑joint. Different job, different symptoms, and serviced separately per the steering section of the Repair Manual.

• Prius driveline uses CV joints, not U‑joints (Toyota NCF, Repair Manual).
• FWD: transaxle to front hubs via CV shafts — no tailshaft.
• AWD‑e: rear motor unit — no centre prop shaft, so no U‑joints.

Does a 2019 Toyota Prius have universal joints that need servicing?

No. There are no driveline universal joints on the 2019 Prius, whether FWD or AWD‑e. The service items that play the same role are the front CV joints and boots. During regular servicing, it’s smart to check the CV boots for cracks or grease leaks and listen for clicking on tight turns. Many workshops give them a look at each service interval or at least every 10,000–15,000 kilometres.

What symptoms might feel like a bad U‑joint on a Prius?

Clicking on acceleration while turning is usually a worn outer CV joint, not a U‑joint. A steady vibration at motorway speeds is more likely out‑of‑balance tyres, a bent rim, or a worn engine or transaxle mount. Because there’s no tailshaft, classic U‑joint thumps or rotational clunks under load changes aren’t typical Prius issues.

If my 2019 Prius is AWD‑e, is there any rear driveshaft to service?

No rear prop shaft is fitted. The AWD‑e system uses a self‑contained rear motor and reduction gear on the axle. There are no rear U‑joints. Routine care focuses on tyre rotations, matching tyre sizes and tread depths front to rear, and following Toyota’s guidance for fluids in the transaxle and the rear drive unit if specified for your market.
