Parts for your 2013 Suzuki Sx4-Centre bearing

2013 Suzuki SX4 centre-bearing

Based on factory information, a centre-bearing is only relevant to 2013 Suzuki SX4 models equipped with the on-demand All-Wheel Drive system. The Suzuki SX4 Service Manual (Driveline/Propeller Shaft section for 2010–2013 models) details a two-piece propeller shaft with a centre support bearing for AWD variants, while the Suzuki Electronic Parts Catalogue lists a centre support bearing/bracket assembly specifically for AWD. Front-Wheel Drive (2WD) SX4 models are built without a propeller shaft, so there’s no centre-bearing fitted.

Why it’s not used on 2WD SX4: the transaxle drives the front wheels via short drive shafts and CV joints, so there’s no long propeller shaft to the rear and no need for a mid‑span support bearing. That’s why owners of 2WD SX4s won’t find a centre-bearing under their car.

For AWD SX4 owners, the centre-bearing plays a key role. It sits mid-way along the two-piece prop shaft, holding the shaft in alignment and isolating vibration through a rubber mount. By supporting the shaft, it stops whip at speed, reduces droning and buzzing in the cabin, and helps keep the universal joints and rear diff happy. In Aussie and Kiwi conditions—think corrugated gravel, coastal salt, and plenty of stop–start—it’s a hardworking part.

Signs the centre-bearing is on the way out include a low-frequency hum or drone between about 40–80 km/h, a shudder on take-off, a thump when shifting from reverse to drive, or visible cracking and sagging of the rubber support. During routine servicing, it’s good practice to:

• Inspect the rubber support for splits, separation or oil swelling.
• Check for excessive shaft movement at the bearing and spin for roughness.
• Confirm bracket bolts are tight and the bearing sits square (no tilt).
• Look over adjacent components: prop shaft joints, diff mount and exhaust clearances.

Replacement isn’t complex but does need care. The shaft should be marked for phasing before separation, and the bearing assembly pressed off/on in the correct orientation. Follow the Suzuki torque specs for the flange and bracket fasteners, and if the shaft halves are separated, get them aligned and balanced. Most centre-bearings are sealed-for-life—there’s no greasing point—so when the bearing or the rubber support is worn, the fix is replacement. Using quality parts and renewing any stretched hardware helps avoid repeat vibrations. After fitting, a quick road test on a smooth road at various speeds will confirm the repair’s spot on.

Popular questions

Does every 2013 SX4 have a centre-bearing?
No. Only AWD (i-AWD) versions have a centre-bearing because they run a two-piece propeller shaft to the rear differential. 2WD models don’t have a prop shaft, so there’s no centre support bearing fitted.

What are the common signs a centre-bearing needs replacement?
Listen for a droning or humming noise at road speed, a vibration on take-off or under light throttle, and a dull clunk shifting between drive and reverse. Under the car, look for cracked or sagged rubber around the bearing and any free play in the shaft at the bracket.

Can the SX4 centre-bearing be serviced or greased?
It’s a sealed unit, so there’s no greasing point. Maintenance is inspection and ensuring the bracket is tight and true. If the bearing is noisy or the rubber support is perished, replacement is the correct remedy.
