Parts for your 2022 Toyota Aqua-Centre bearing

2022 Toyota Aqua centre-bearing: what’s actually fitted

Based on Toyota’s service literature for the 2022 Aqua (model codes MXPK11/MXPK16), the Toyota Electronic Parts Catalogue (EPC), and Toyota’s technical outline for the TNGA-B platform and E-Four system, a traditional tailshaft centre-bearing is not used on this vehicle. The Aqua runs a transverse front-wheel-drive hybrid layout, and the optional E-Four grade drives the rear wheels via a dedicated rear electric motor, not a mechanical prop shaft. With no two-piece propeller shaft, there’s no need for a centre-bearing.

What sometimes causes confusion is wording. Some FWD Toyotas use a short front “intermediate shaft” on the right-hand side with a block-mounted support bearing. Toyota service manuals list this as an intermediate shaft support bearing within the front drive shaft section, not a centre-bearing. The EPC for the 2022 Aqua lists front drive shafts and, where applicable, that intermediate shaft and its bracket/bearing — but there’s no propeller shaft or centre support bearing assembly in the driveline group.

• Drivetrain layout: TNGA-B, transverse engine/transaxle, no longitudinal tailshaft.
• E-Four AWD: independent rear electric drive, no prop shaft between axles.
• Parts evidence: EPC shows front drive shafts/intermediate shaft only, no centre-bearing assembly.

For owners chasing a noise they think is “centre-bearing” related, the smarter checks on a 2022 Aqua are the front CV joints and boots, the intermediate shaft support bearing (if fitted on their grade), front wheel bearings, engine and transaxle mounts, and tyre condition. These are the components that, in this layout, can create droning, vibration on throttle, or clicking on lock.

Referencing Toyota’s Repair Manual and EPC means the call is straightforward: the 2022 Aqua doesn’t run a tailshaft centre-bearing because the vehicle has no tailshaft. If a support bearing is needed on the front intermediate shaft, it’s serviced as part of the front drive system and is a different part and procedure from a traditional centre-bearing found on utes or rear-drive wagons.

• Popular questions

Does a 2022 Toyota Aqua have a centre-bearing?
No. The Aqua’s front-drive hybrid layout and optional E-Four electric rear axle remove the need for a propeller shaft, so there’s no tailshaft centre-bearing fitted. Toyota’s EPC for MXPK11/MXPK16 lists only front drive shafts (and an intermediate shaft on some variants), confirming there’s no centre support bearing in the driveline.

What part gets mistaken for a centre-bearing on the Aqua?
The right-hand front intermediate shaft support bearing. It’s a small carrier bearing that bolts to the engine block to support the short shaft and keep torque steer in check. It’s part of the front drive shaft system, not a tailshaft centre-bearing, and is serviced with front driveline components.

What should be checked if there’s a droning or vibration in a 2022 Aqua?
Start with the front CV joints and boots, the intermediate shaft support bearing (if equipped), front wheel bearings, engine/trans mounts, and tyre balance/cupping. There’s no tailshaft or centre-bearing to inspect, so any noise or vibration will usually trace back to those front-end items.
