Parts for your 2017 Toyota Prius-Universal joints

2017 Toyota Prius universal-joints: are they used?

Short answer: universal joints aren’t a drivetrain part on the 2017 Toyota Prius. The Prius is front‑wheel drive with a hybrid transaxle and front drive shafts that use constant‑velocity (CV) joints, not cross‑type universal joints found on rear‑wheel drive propeller shafts. There’s no long prop shaft to the rear axle, so no drivetrain U‑joints to replace or maintain.

Technical sources that establish this:

• Toyota New Car Features (NCF) for Prius ZVW50/51 (2016–2018): details the P610 hybrid transaxle and front drive shafts with tripod (inboard) and Rzeppa (outboard) CV joints, no propeller shaft is used.
• Toyota Repair Manual (RM) for ZVW50 series: includes Drivetrain/Axle sections for front drive shafts and CV boots, there’s no U‑joint service procedure or propeller shaft section for this model.
• Toyota Electronic Parts Catalogue (EPC) for ZVW50: lists front drive shafts, CV joints and boots, and transaxle components, no universal‑joint or propeller‑shaft part numbers for the drivetrain.
• SAE Technical Paper 2016‑01‑1168 (Toyota): development of the P610 hybrid transaxle for a front‑drive architecture, confirming the FWD layout with CV joints.

Why universal‑joints aren’t used on this Prius comes down to its layout and efficiency focus. The TNGA‑based 2017 Prius drives the front wheels through an e‑CVT hybrid transaxle. Drive is sent to short front half‑shafts that must handle large steering angles and suspension movement smoothly, which is exactly what CV joints are designed for. Universal joints are common on longitudinal, rear‑drive prop shafts where the angle range is smaller, they’re not ideal for constant speed at high steering angles. Even on later Prius grades that offered electric AWD (not typical for 2017 in Australia or New Zealand), the rear axle is driven by a separate electric motor, so there’s still no mechanical prop shaft or U‑joints.

For owners thinking about “universal‑joints” on a 2017 Prius, the practical maintenance focus should be on the CV joints and boots. During servicing, a technician will check CV boots for splits or grease fling, listen for clicking on full lock, and inspect transaxle seals for seepage. Note that the steering column does use a small universal joint in the intermediate shaft, but it’s not a routine service item, it’s only addressed if there’s play, stiffness, or corrosion.

FAQs

Does a 2017 Toyota Prius have universal joints?
Not in the drivetrain. The 2017 Prius uses front drive shafts with CV joints and has no propeller shaft, so there are no cross‑type U‑joints to service. A small universal joint exists in the steering intermediate shaft, but that’s separate from the drivetrain and rarely needs attention unless there’s wear or binding.

What joints does it use instead, and how often should they be checked?
It uses CV joints: typically a tripod joint inboard and a Rzeppa joint outboard. At each service, technicians should inspect CV boots for cracks or grease leaks and road test for clicking noises on full lock. If a boot is torn, acting early can often save the joint from grit damage.

What should be maintained instead of U‑joints on a Prius?
Focus on CV boots and drive shafts, front wheel bearings, and transaxle axle seals. The steering intermediate shaft U‑joint isn’t a scheduled item, but if the steering feels notchy or there’s visible corrosion at the joint, it should be inspected.
