Parts for your 2006 Toyota Ractis-Centre bearing

2006 Toyota Ractis centre-bearing: is it there and what to do about it

Checking Toyota’s technical references for the XP100-series Ractis (2005–2010) — specifically the Toyota Electronic Parts Catalogue for JDM models and the Toyota Ractis Chassis/Drivetrain Repair Manual — shows two driveline setups:

• NCP100/NCP101 (front‑wheel drive): no propeller shaft is listed, so a centre-bearing is not used or relevant.
• NCP105 (four‑wheel drive): a two‑piece propeller shaft is shown, with a “Bearing Assy, Centre Support, Propeller Shaft” specified.

For the common 2WD Ractis, a centre-bearing isn’t fitted because the transaxle drives the front wheels directly. There’s no long prop shaft running down the tunnel, so there’s nothing that needs a mid‑span support. If the vehicle is the 4WD NCP105, it does have a centre-bearing as part of the two‑piece propeller shaft to the rear diff.

On 4WD Ractis models, the centre-bearing supports the long propeller shaft between the gearbox and the rear differential, keeping the shaft aligned and reducing vibration. It sits in a rubber carrier that isolates noise and harshness, helping the little Toyota feel smooth on motorway runs and over rough chipseal — classic New Zealand and Aussie conditions. When the bearing or its rubber mount ages, owners might notice a droning or humming that rises with speed, a shake under load, or a thud on take‑off as the shaft moves more than it should.

As part of regular servicing on a 4WD Ractis, it’s smart to check the centre-bearing at the same time as engine oil, tyres, and suspension inspections. A quick look for perished rubber, torn carrier mounts, or shiny witness marks from contact can save a lot of hassle later. Spinning the shaft by hand (with the car safely supported) and feeling for roughness in the bearing is another good tell. Many workshops in Australia and New Zealand roll this into WOF/roadworthy checks and 20,000–30,000 km services.

If replacement is needed, the best practice is to mark the prop shaft flanges so the original phasing is maintained, remove the shaft, and press off the old bearing and carrier. Most techs replace the bearing and the rubber support together to restore proper isolation. It’s also a good time to inspect universal joints and the centre hanger bracket. After reassembly, correct alignment of the two‑piece shaft is crucial to avoid vibrations, a quick road test at open‑road speeds helps confirm it’s spot on. Sticking with a quality OEM or reputable aftermarket centre-bearing is worth it — the prop shaft runs at engine speed multiples, so balance and bearing quality make a noticeable difference inside the cabin.

For drivers unsure whether their 2006 Ractis is 2WD or 4WD, a glance under the rear shows it quickly: a rear differential and a prop shaft pointing forward means 4WD (NCP105), if it’s a simple torsion beam with no diff, it’s 2WD (NCP100/NCP101) and there’s no centre-bearing to worry about.

Does every 2006 Toyota Ractis have a centre-bearing?

No. The 2WD Ractis (NCP100/NCP101) doesn’t use one. The 4WD Ractis (NCP105) has a two‑piece propeller shaft with a centre-bearing. Check for a rear diff or confirm the chassis code on the build plate to be sure.

What are the signs a Ractis centre-bearing needs replacement?

Typical clues include a low drone that changes with road speed, vibration under acceleration, and a clunk on take‑off or when shifting from drive to reverse. Visual checks may show cracked or separated rubber around the carrier, or excess play at the support point.

How often should the centre-bearing be inspected on a 4WD Ractis?

Have it looked over during regular servicing or WOF/roadworthy inspections, roughly every 20,000–30,000 km. If the car tows, carries loads, or does lots of rough‑road kilometres, more frequent checks are wise. Replace at the first sign of noise, play or rubber deterioration to avoid prop shaft vibration and collateral wear.
