Parts for your 2006 Mazda Axela-Centre bearing

2006 Mazda Axela centre-bearing — does it have one?

Short answer: a 2006 Mazda Axela (BK series) doesn’t use a centre-bearing. On this model the driveline is front‑wheel drive, so there’s no long, two‑piece propeller shaft running to the rear that would need a centre (prop) support bearing. Technical references that back this up include the Mazda 3/Axela BK Workshop Manual (Driveline/Axle sections list front drive shafts and an intermediate shaft only), the Mazda Electronic Parts Catalogue (EPC) for BK models (no propeller shaft or centre support bearing listed for Axela), and general service guides such as the Haynes Mazda 3 2004–2011 manual, which cover FWD layouts with no centre-bearing.

Why it’s not used: the Axela’s transaxle sits up front and drives the front wheels via two short drive shafts. Some variants use a right‑hand intermediate shaft with a support bracket and bearing that bolts to the engine block. That part is often called an intermediate shaft support bearing or carrier bearing, but it’s not a prop‑shaft centre-bearing. Because there’s no rear differential or prop shaft on the BK Axela, there’s simply nothing for a centre-bearing to support.

Hearing a rumble or feeling vibration and wondering about a “centre-bearing”? On this car, look elsewhere first. Common culprits include:

• Right‑hand intermediate shaft support bearing (if fitted) starting to growl under load
• Outer or inner CV joints clicking, shuddering, or humming
• Front wheel bearings humming that changes with road speed
• Engine and transmission mounts causing take‑off shudder
• Tyre wear or balance issues, especially on low‑profile rubber

If chasing parts, and a catalogue lists a “centre-bearing” for a 2006 Axela, it’s usually a mislabelled intermediate shaft support bearing. Typical signs of a tired support bearing are a steady-speed rumble that worsens when loading the right drive shaft, slight play at the bearing bracket when the shaft is unloaded, and grease staining. Replacement involves removing the right shaft assembly, unbolting the bracket from the block, pressing off the bearing, and fitting a quality replacement with correct orientation and seals. Always torque the bracket fasteners to spec from the service manual, recheck driveshaft circlips, and finish with a wheel alignment if the suspension was disturbed.

For routine servicing, keep an eye on:

• CV boots for splits and grease fling
• Any free play or roughness at the intermediate shaft support
• Wheel bearing noise on test drives
• Mount condition and tyre pressures/rotation

Popular questions about 2006 Mazda Axela centre-bearing

Does a 2006 Mazda Axela have a centre-bearing?
No. The BK‑series Axela is front‑wheel drive and doesn’t use a propeller shaft, so there’s no centre (prop) support bearing. If you’re diagnosing a rumble, check the right‑hand intermediate shaft support bearing (if fitted), CV joints, and front wheel bearings instead.

What’s the difference between a centre-bearing and the Axela’s intermediate shaft support bearing?
A centre-bearing supports the middle of a long, two‑piece rear propeller shaft on RWD/AWD vehicles. The Axela’s intermediate shaft support bearing is a small bearing and bracket that supports the short right‑hand front drive shaft, it’s engine‑mounted and part of the FWD layout, not a chassis centre support for a prop shaft.

What should be serviced if I thought I needed a centre-bearing?
On a 2006 Axela, ask for inspection of the right‑hand intermediate shaft support bearing, CV joints and boots, front wheel bearings, and engine/trans mounts. Many “centre-bearing” noises end up being a worn wheel bearing or a dry CV joint on these cars.
