Parts for your 2012 Nissan Serena-Centre bearing

2012 Nissan Serena centre-bearing: what’s fitted and when it matters

Technical sources show that a centre-bearing is not used on front-wheel-drive (FF) 2012 Nissan Serena models, but it is used on the 4WD variants. The Nissan Serena C26 Electronic Service Manual (ESM) details a two-piece propeller shaft with a centre (support) bearing on 4WD models (often referenced under Propeller Shaft/Driveline sections for NC26). In contrast, FWD C26 models only list front drive shafts in the Front Axle sections and have no propeller shaft or centre support bearing. Nissan’s FAST/EPC parts catalogue also lists a “Centre Support Bearing – Propeller Shaft” under Group 370 for NC26 (4WD), and there’s no equivalent listing for FF models.

Why no centre-bearing on FWD Serena? The FWD layout mounts the engine transversely and sends drive to the front wheels via short left and right drive shafts. There’s no long propeller shaft running to the rear, so there’s nothing needing mid-span support. A centre-bearing is only relevant when a long, two-piece prop shaft is used, which is the case on the 4WD Serena with a rear differential.

For owners of a 2012 Serena 4WD, the centre-bearing earns its keep by supporting the two-piece prop shaft, keeping it aligned and quiet. In day-to-day driving, it tames vibration and prevents the shaft from whipping about as loads change through the CVT and transfer to the rear diff. If that rubber-mounted bearing starts to go, the tell-tales are a droning or humming that rises with road speed, a shudder on take-off, or a thump when shifting from drive to reverse. Left too long, it can stress the prop shaft and rear driveline.

Servicing-wise, there’s no fixed replacement interval, but a good workshop will inspect the centre-bearing at each service. They’ll check for play in the bearing, splits in the rubber support, and rust staining or heat discolouration. Typical triggers for replacement are high kilometres, heavy loads, or regular rough-road use. When changing the bearing, mark the prop shaft halves so they go back in the same orientation (to preserve balance), torque the support bracket evenly, and recheck driveline angles if mounts have been disturbed. Genuine Nissan supplies the prop shaft as an assembly on some models, but quality aftermarket centre-bearings are available and a driveline specialist can press the old unit off and install the new one. If there’s still vibration after replacement, look at the rear universal joint(s), centre hanger alignment, and prop shaft balance. With a fresh centre-bearing and correct fit-up, the Serena 4WD stays smooth, quiet, and happy on long hauls.

• Common symptoms of wear: hum/droning with speed, take-off shudder, clunk on load change.
• Service tip: always match-mark the shaft, don’t preload the rubber when tightening the support.
• Driving conditions that accelerate wear: towing, heavy loads, corrugations, and frequent short trips.

How can an owner tell if their 2012 Serena has a centre-bearing?
It’s fitted to 4WD models. A quick check under the vehicle will show a propeller shaft running to a rear differential, with a support bracket roughly mid-way. Model codes and badges can help too: NC26 (4WD) typically has the prop shaft, FF C26 (2WD) does not. If unsure, a mechanic can confirm in minutes on a hoist.

How often should the centre-bearing be replaced?
There’s no set time or kilometre interval. It’s condition-based: inspect at each service and replace if there’s bearing play, torn rubber, or noise/vibration under load. Many last well past 150,000 km in easy use, while vehicles that tow or see rough roads may need one sooner.

Can the centre-bearing be replaced on its own, or is a full prop shaft needed?
On many Serena 4WDs, Nissan lists the complete propeller shaft assembly, but reputable aftermarket bearings are available. A driveline shop can press off the old bearing and fit a new one, then check balance and alignment. If universal joints are staked and worn, a complete shaft may be the smarter fix.
