Parts for your 2013 Mazda Cx-5-Centre bearing

2013 Mazda CX-5 centre-bearing: what it is, whether it’s fitted, and how to look after it

Technical conclusion (with sources): On the 2013 Mazda CX-5 (KE series), a centre-bearing is fitted on All-Wheel Drive (AWD) models because they use a two-piece propeller shaft with a centre support bearing and bracket. Front-Wheel Drive (FWD) models do not have a propeller/drive shaft to the rear, so no centre-bearing is used. This layout is confirmed in the Mazda KE CX-5 Workshop Manual (Driveline/Axle – Propeller Shaft section, which shows the two-piece shaft and support), the Mazda Electronic Parts Catalogue (Propeller Shaft group, centre support listed for AWD only), and common aftermarket catalogues that list a centre support bearing specifically for 2012–2016 CX-5 AWD variants.

On AWD 2013 CX-5s, the centre-bearing lives halfway along the prop shaft, bolted to the body with a rubber isolator. Its job is to support the shaft, keep it aligned, and dampen vibration while allowing a bit of movement as the suspension and engine mounts do their thing. That steadying role is what keeps take-off shudder and highway drone to a minimum.

It’s a sealed unit, so there’s no greasing on a normal service, but it’s smart to have a quick look during routine maintenance. Every 10,000–15,000 km, a workshop can check for perished rubber, torn mount, or play in the bearing. On-road symptoms worth noting include:

• Dull rumble or humming that changes with road speed
• Vibration under load or a shudder on take-off
• Clunk when shifting from drive to reverse, after other causes are ruled out

Replacement on this model is straightforward for a pro: the shaft is marked for orientation, flanges are loosened, the centre bracket is unbolted, and the shaft is removed. Many CX-5s are serviced by replacing the complete prop shaft assembly, as the centre-bearing isn’t always supplied separately by Mazda, however, quality aftermarket bearings and rebuild services exist. If the shaft is split for bearing work, it should be reassembled to factory marks and checked for balance. New fasteners, correct torque, and inspecting the CV joints and boots at each end are best practice whilst it’s out.

There isn’t a fixed replacement interval—these bearings often run well past 150,000 km—but life depends on road conditions and load. It’s worth addressing early if symptoms appear, as a failing support can take out CV joints or accelerate tyre and driveline wear.

Note for FWD owners: the 2013 CX-5 FWD doesn’t use a centre-bearing at all because its transverse engine and transaxle don’t drive a rear prop shaft.

Does every 2013 Mazda CX-5 have a centre-bearing?

No. Only AWD models have a centre-bearing because they use a two-piece propeller shaft to drive the rear differential. FWD models don’t have a rear prop shaft, so there’s no centre support bearing to service or replace.

What are the typical signs the CX-5’s centre-bearing needs attention?

Common clues are a speed-related rumble, vibration on acceleration, or a light shudder taking off from the lights. If those sounds shift with road speed rather than engine revs, the centre-bearing or prop shaft alignment is a good suspect. A workshop can confirm by inspecting the rubber support, checking bearing play, and ruling out tyre, wheel, and engine mount issues.

Can the centre-bearing be replaced on its own, or is it a full prop shaft job?

Many workshops replace the complete prop shaft assembly, especially if sourcing genuine parts. However, reputable aftermarket centre-bearings are available, and driveline specialists can rebuild the shaft with a new support and re-balance it. The best route depends on parts availability, cost, and the condition of the CV joints and boots at the same time.
