Parts for your 2018 Honda Accord-Centre bearing

2018 Honda Accord centre-bearing: is it actually a thing?

Short answer: a centre-bearing (also called a tailshaft carrier bearing) isn’t fitted to the 2018 Honda Accord. That part is used on vehicles with a long, two-piece propeller shaft — typically rear‑wheel drive or all‑wheel drive utes and SUVs. The 2018 Accord is front‑wheel drive with a transverse engine and a transaxle, so there’s no tailshaft running down the middle of the car and no centre-bearing to support it.

Why it’s not used on this model comes down to layout. The Accord’s engine and transmission send power straight to the front wheels via short driveshafts (half‑shafts). There’s no need for a multi‑section prop shaft, so the classic centre-bearing simply doesn’t come into play. Some FWD Hondas, including 2018 Accord variants, do use a right‑hand intermediate shaft with a support bearing mounted to the engine block to help equalise shaft lengths and reduce torque steer. That bearing is often called an intermediate shaft or carrier bearing, but it’s a different bit of kit to a tailshaft centre-bearing and it’s not serviced the same way.

Technical sources that confirm this setup:

• Honda Accord (2018) Service Manual – Driveline/Axle: details front driveshafts and the right‑hand intermediate shaft, there’s no propeller shaft or centre support bearing section.
• Honda EPC/parts catalogue for 2018 Accord: lists front driveshaft assemblies and an intermediate shaft with support bracket/bearing on the RH side, no centre-bearing assembly exists for the model.
• Honda technical specifications and press materials for the 10th‑gen Accord: front‑wheel drive architecture with transaxle, eliminating the need for a prop shaft.

If a driver’s chasing a drone or vibration and wondering about a centre-bearing on a 2018 Accord, it’ll be coming from somewhere else. Usual suspects include front wheel bearings, inner CV joints, engine/trans mounts, tyres (cupping or out‑of‑round), or — less commonly — the RH intermediate shaft support bearing. That intermediate bearing is sealed and not a service item, it’s replaced only if noisy, rough or showing play.

Bottom line: there’s no tailshaft centre-bearing to maintain or replace on a 2018 Honda Accord. If there’s a rumble under load or a speed‑related hum, book an inspection that focuses on front wheel bearings, CV joints, tyre condition and balance, and the RH intermediate shaft assembly.

• Does a 2018 Honda Accord have a centre-bearing?
• What’s the bearing on the right‑hand intermediate shaft, and does it need servicing?
• I’ve got a vibration on acceleration — could it be a centre-bearing on my 2018 Accord?

Does a 2018 Honda Accord have a centre-bearing?
No. The car is front‑wheel drive and doesn’t use a two‑piece tailshaft, so there’s no tailshaft centre-bearing fitted. Any mid‑car bearing you might read about on other vehicles doesn’t apply to this model.

What’s the bearing on the right‑hand intermediate shaft, and does it need servicing?
That’s a support bearing for the RH intermediate driveshaft. It’s sealed, not greasable, and isn’t a routine service item. Replace it only if there’s noise, roughness or measurable play during inspection.

I’ve got a vibration on acceleration — could it be a centre-bearing on my 2018 Accord?
Not a tailshaft centre-bearing. On this Accord, check front wheel balance and tyres first, then inner CV joints, engine/trans mounts, and the RH intermediate shaft support bearing if symptoms persist.
