Parts for your 2018 Honda Civic-Centre bearing

2018 Honda Civic centre-bearing – do you actually need one?

Short answer: a centre-bearing isn’t used on the 2018 Honda Civic. The Civic runs a front-wheel-drive transaxle with two front drive shafts (CV axles) and no tailshaft running down the middle of the car, so there’s nothing that needs a centre support bearing like you’d see on a rear-wheel-drive or 4x4 with a two-piece tailshaft.

Technical sources back this up. Honda’s 2016–2021 Civic service information describes a transverse engine/transaxle layout driving the front wheels only, and Honda’s parts catalogues for 2018 Civic variants show no propeller shaft or centre support bearing assembly. Industry references on FWD transaxle architecture also note that centre-bearings are specific to multi-piece tailshafts in RWD/AWD layouts, not to FWD cars like the Civic.

Why it isn’t used on the Civic comes down to packaging and design. A centre-bearing supports the middle of a long, two-piece tailshaft to control vibration and keep alignment in check. The Civic doesn’t have that shaft at all. Instead, it uses compact left and right CV axles. Some Civic variants do run a right-hand intermediate shaft with a support bearing that bolts to the engine block to help keep axle lengths equal and reduce torque steer. That part is often called an intermediate shaft support bearing, not a centre-bearing, and it’s a different job to a tailshaft carrier bearing.

If someone’s listed a “centre-bearing” for a 2018 Honda Civic, it’s usually a catalogue mix-up or shorthand for the front intermediate shaft support bearing. For driveline servicing on these cars, attention is better spent on CV joints/boots, axle seals, wheel bearings, and the intermediate shaft support bearing (where fitted).

FAQs

Does a 2018 Honda Civic have a centre-bearing?
No. There’s no tailshaft in a FWD Civic, so a centre-bearing isn’t part of the car. Some trims use a right-hand intermediate shaft with a support bearing, which is a different component and purpose.

What symptoms point to a worn intermediate shaft support bearing on a Civic?
A dull humming or whirring that rises with road speed, vibration under load, or signs of heat and play at the bearing mount can point to wear. Always rule out front wheel bearings and inner CV joints first, as they can sound similar.

If I find a “centre-bearing” listing for my 2018 Civic, what is it likely referring to?
It’s usually a mislabelled listing for the intermediate shaft support bearing on the right-hand driveshaft assembly, or a generic category that doesn’t apply to the Civic’s FWD layout.
