Parts for your 2003 Honda Accord-Centre bearing

2003 Honda Accord centre-bearing: is it actually a thing?

Short answer: a traditional tailshaft centre-bearing isn’t fitted to the 2003 Honda Accord. Technical references including the Honda Accord 2003–2007 Service Manual (Driveline/Axle sections) and the Honda Electronic Parts Catalogue show no propeller shaft or centre support bearing listed for this model. That’s because the Accord of this era is front‑wheel drive with a transverse engine, so it drives the front wheels via two short front driveshafts (CV axles) rather than a long rear prop shaft that would need a centre-bearing.

On vehicles with rear‑wheel or all‑wheel drive and a two‑piece tailshaft, a centre-bearing supports the shaft mid‑span. The 2003 Accord doesn’t use that layout, so there’s nothing to support in the middle. Instead, power goes through a transaxle to the front hubs. This design eliminates the need for a centre-bearing entirely (again, confirmed by the Honda service manual contents and parts groupings that lack any “propeller shaft” or “centre support bearing” for this chassis).

One gotcha: some 2003 Accord variants (including many V6 and “Euro/CL9” style K24 models) have an intermediate shaft on the right‑hand side with a support bearing bolted to the engine block. In Honda literature this is an “intermediate shaft bearing,” not a tailshaft centre-bearing. It’s a different part doing a different job, and it appears under the Intermediate Shaft group in the Honda parts catalogue, not under a propeller‑shaft section that doesn’t exist for this car.

If an owner is chasing a droning or vibration and assuming “centre-bearing,” it’s more likely to be one of the usual front‑drive suspects:

• Front wheel bearings starting to rumble with speed
• Outer or inner CV joints clicking or vibrating on load
• Engine or trans mounts sagging and transferring vibration
• On models with an intermediate shaft, play in that support bearing
• Tyre cupping or imbalance after suspension wear

Service advice for this Accord focuses on regular checks of CV boots for splits, listening for wheel‑bearing hum that changes with steering load, and inspecting mounts. Where fitted, the intermediate shaft bearing should be checked for roughness or movement when the shaft is removed (per the Honda Service Manual procedure). But a classic tailshaft centre-bearing simply isn’t part of the 2003 Accord’s driveline.

Does a 2003 Honda Accord have a centre-bearing?

No. Technical sources (Honda Accord 2003–2007 Service Manual and Honda EPC) show no propeller shaft or centre support bearing on this front‑wheel‑drive platform. There’s nothing to support mid‑shaft because there’s no tailshaft.

What’s the “bearing on the right‑hand side shaft” some mechanics mention?

That’s the intermediate shaft support bearing used on some K24 and J‑series V6 Accords. It supports the short intermediate shaft to help with equal‑length driveshaft geometry. It’s not a tailshaft centre-bearing and is serviced under the intermediate shaft procedures and parts listings.

Chasing a hum or vibration that sounds like a centre-bearing?

On this Accord, look first at front wheel bearings, CV joints, and tyres. If the model has an intermediate shaft, its support bearing can also wear. A road test that loads the bearings (gentle lane change) and an inspection of CV boots and mounts usually points in the right direction.
