Parts for your 2014 Mazda Cx-5-Centre bearing

2014 Mazda CX-5 centre-bearing: is it fitted, what it does, and when to service it

Whether a 2014 Mazda CX-5 uses a centre-bearing depends on the drivetrain. According to Mazda’s Workshop Manual for the 2013–2016 CX-5 (Propeller Shaft section) and the Mazda parts catalogue, front-wheel drive (FWD) models do not have a propeller shaft, so there’s no centre-bearing. All-wheel drive (AWD) models use a two-piece propeller shaft with a centre support bearing (centre-bearing) mounted to the body to control shaft alignment and vibration. Mazda’s i-ACTIV AWD technical overview further confirms the AWD hardware adds a power transfer unit, prop shaft and rear differential—hardware that necessitates a centre-bearing.

• FWD 2014 CX-5: No centre-bearing (no propeller shaft).
• AWD 2014 CX-5: Yes, a centre-bearing is fitted on the propeller shaft.

Why FWD models don’t use a centre-bearing: With the engine mounted transversely and power sent directly to the front wheels via short drive shafts, there’s no long propeller shaft running the length of the vehicle. A centre-bearing is only relevant to longer, multi-piece shafts used on AWD or rear-drive layouts. On FWD CX-5s, servicing instead focuses on CV joints/boots, wheel bearings and mounts.

For AWD owners, the centre-bearing plays a quiet but crucial role. It supports the middle of the two-piece propeller shaft, keeping everything straight under load and soaking up vibrations through its rubber isolator. That means smoother take-offs, less droning on the motorway and reduced wear on the universal joints, transfer case and rear diff. It’s a sealed component, so there’s no routine lubrication, but it does like a periodic once-over. During regular servicing—especially if the car clocks up a lot of Kiwi back roads or Aussie corrugations—have the technician check the bearing for excessive play, torn rubber, rust around the bracket and any sagging. Common tell-tales of a tired centre-bearing include a low-frequency rumble at 60–100 km/h, a shudder on take-off, or a thump when shifting from Drive to Reverse.

If replacement’s needed, correct procedure matters. The propeller shaft phasing should be marked before removal, fasteners torqued to spec, and heat shields re-fitted properly. Mazda’s service information commonly supplies the propeller shaft as a complete assembly, some independent workshops can replace just the centre-bearing with quality components, but shaft balance and alignment must be checked to avoid new vibrations. It’s smart to pair a new centre-bearing with an inspection of the universal joints and mounts, and to road-test for NVH under different loads. In coastal areas, keep an eye on corrosion around the bearing bracket. As a rule of thumb, inspect at major services or every 60,000–80,000 kilometres, and act promptly if symptoms pop up—letting a failing bearing go can snowball into pricier driveline repairs.

• How can someone tell if their 2014 CX-5 has a centre-bearing?

If it’s AWD, it has one. A quick check: look underneath—AWD cars have a propeller shaft running to the rear diff with a support mount roughly midway. The build plate, owner’s manual and service records will also note AWD. FWD cars won’t have the long shaft or the centre mount.

• What does a worn centre-bearing sound or feel like?

Typical signs include a droning or humming that rises with road speed, a vibration on take-off, and sometimes a dull clunk when shifting between Drive and Reverse. Tyres and wheel bearings can mimic some of these, so a proper inspection is wise.

• Can the centre-bearing be replaced on its own?

Mazda often supplies the propeller shaft as a complete assembly, but many reputable workshops can press in a new centre-bearing. If going that route, correct phasing and shaft balance are essential to avoid new NVH issues.
