Parts for your 2021 Honda Odyssey-Centre bearing

2021 Honda Odyssey centre-bearing: is it fitted, and does it matter?

Based on Honda’s own technical literature, a centre-bearing is not used on the 2021 Honda Odyssey. The factory Service Information for the RL6-series Odyssey (Driveline/Axle section) details front half‑shafts and an intermediate (jack) shaft only, there’s no propeller shaft or centre support bearing assembly listed. The Honda Electronic Parts Catalogue for 2021 Odyssey likewise shows no centre-bearing component, it lists front driveshafts, an intermediate shaft with a pressed support bearing and bracket, wheel hub bearings, and related hardware—nothing resembling a longitudinal prop shaft carrier bearing. This aligns with the vehicle’s layout: the 2021 Odyssey is front‑wheel drive with a transverse V6 and transaxle, so it doesn’t need a multi‑piece prop shaft or the centre-bearing that typically supports one.

Why no centre-bearing? Centre-bearings are used on rear‑wheel drive and many all‑wheel drive vehicles to support a long, two‑piece prop shaft running to a rear differential. The Odyssey’s powertrain sends drive straight to the front wheels via short half‑shafts, so there’s no long shaft down the centre of the vehicle to support. That packaging saves weight and complexity and keeps NVH (noise, vibration, harshness) well controlled without the extra bearing and hanger.

If someone’s chasing “centre-bearing” noises on a 2021 Odyssey—think droning, rumbling, or vibration under load—there are a few more likely culprits on this FWD setup:

• Intermediate shaft support bearing (pressed onto the RH jackshaft, mounted to the engine block bracket)
• Front driveshaft CV joints and boots (inner tripod joints can cause shudder under load)
• Front wheel hub bearings (often drone and change tone when cornering)
• Engine and transmission mounts (can transmit vibration under throttle)
• Tyre cupping or uneven wear

Service advice for workshops and owners: treat the intermediate shaft support bearing like a regular wear item if symptoms appear. Check for play or roughness with the vehicle safely raised, spin and feel the intermediate shaft with the belt off and the wheel free, and inspect the bracket bushings and fasteners. Replace the bearing if there’s noticeable roughness, noise, or movement. While you’re there, inspect CV boots for splits or grease sling and listen for clicking on lock—repack or replace as needed. A road test on varying throttle at 60–100 km/h helps isolate whether the noise is wheel‑speed (tyres/wheel bearings) or torque‑dependent (CVs/intermediate bearing). Correct torque on axle nuts and bracket bolts, and proper driveshaft seating, are essential to prevent repeat NVH complaints.

Does the 2021 Honda Odyssey have a centre-bearing?

No. The 2021 Odyssey is front‑wheel drive and doesn’t use a centre support bearing. Honda’s service documentation and parts catalogues show only front half‑shafts and an intermediate shaft with its own support bearing and bracket—no prop shaft or centre-bearing assembly.

What’s causing a droning noise at 60–90 km/h if it’s not a centre-bearing?

On this model the usual suspects are front wheel bearings, tyre wear, or the intermediate shaft support bearing. Wheel bearings tend to drone and change tone when you load the corner, the intermediate bearing or inner CV joints often get louder under throttle. A quick A–B test (steady cruise vs light acceleration) helps narrow it down.

Is there any driveline bearing on the Odyssey that needs attention instead?

Yes—the intermediate (jack) shaft support bearing and the front wheel hub bearings. Inspect the intermediate bearing for play or roughness during servicing, and keep an eye on CV boots and grease condition. Replace components at the first sign of noise, looseness, or torn boots to avoid collateral damage.
