Parts for your 2020 Toyota Prius-Centre bearing

2020 Toyota Prius centre-bearing

The 2020 Toyota Prius doesn’t use a centre-bearing in its driveline. That’s not an oversight, it’s simply how the car’s layout works. The Prius is primarily front-wheel drive with a transaxle that sends power to two short front driveshafts. There’s no long propeller shaft running down the middle of the car, so there’s nothing that needs a centre (centre support) bearing.

Technical references back this up. The Toyota New Car Features manual for the XW50-series Prius describes a P610 hybrid transaxle driving the front wheels. For AWD-e models, Toyota’s documentation explains that the rear axle is powered by a separate electric motor (often called the MGR), with no mechanical driveshaft linking front to rear. Toyota’s Repair Manual, Electrical Wiring Diagram and Electronic Parts Catalogue for 2020 Prius also don’t list a propeller shaft or a centre support bearing for this model line, which is exactly what you’d expect on a FWD or electric-on-demand AWD setup.

Why no centre-bearing on a 2020 Prius? Because:

• Front-wheel drive architecture: The transaxle sits up front and directly drives the two front CV axles.
• AWD-e (if fitted) is electric-only at the rear: The rear motor is self-contained, so there’s no long shaft to support.
• Centre-bearings are for long, two-piece prop shafts in RWD/4WD vehicles, which the Prius doesn’t have.

If a driver is chasing noises or vibrations and thinking “centre-bearing”, it’s smarter on a Prius to look at parts that actually exist on the car:

• Front wheel hub bearings (common source of humming that changes with speed or when cornering)
• Front CV joints/boots (clicking on turns, shudder on take-off if worn)
• Engine and transaxle mounts (vibration at idle or on load)
• Tyre condition, balance and alignment (cupped tyres can drone and feel like a driveline issue)

For anyone used to traditional 4x4s or rear-drive utes, it might feel odd that there’s no centre-bearing to maintain. On a 2020 Prius, routine servicing focuses on the hybrid transaxle fluid at Toyota-recommended intervals, inspecting CV boots, checking wheel bearings for play or noise, and keeping tyres rotated and balanced. That’s the right way to keep a Prius smooth and quiet out on Kiwi and Aussie roads.

FAQs

Does a 2020 Toyota Prius have a centre-bearing?
No. There’s no propeller shaft on this model, so there’s no need for a centre support bearing. The driveline design and Toyota service information confirm this.

What should be checked if there’s a humming or vibration on a Prius?
Start with the front wheel hub bearings, tyre condition and balance, and the CV joints/boots. Engine and transaxle mounts are also worth a look if the vibration is most noticeable at idle or on load.

Is the AWD-e Prius any different regarding a centre-bearing?
Still no centre-bearing. The AWD-e system powers the rear wheels with a dedicated electric motor, so there’s no mechanical driveshaft to support.
