Parts for your 2009 Toyota Vitz|yaris-Centre bearing

2009 Toyota Vitz/Yaris centre-bearing — is it fitted, and does it matter?

Short answer: for the mainstream 2009 Toyota Vitz/Yaris (XP90 series) sold as front‑wheel drive, a centre-bearing isn’t used or relevant. Technical references back this up: Toyota’s New Car Features (NCF) for the XP90 describes a transverse engine with a front transaxle and no propeller shaft, the Toyota Electronic Parts Catalogue (EPC) for FWD models (KSP90, SCP90, NCP91) lists only left and right front drive shaft assemblies with CV joints, and there’s no “centre support bearing” or propeller shaft shown, the factory Repair Manual sections cover Front Drive Shaft and Wheel Bearings, not a prop shaft centre-bearing.

Why isn’t there a centre-bearing on these models? A centre-bearing supports a long, two‑piece propeller shaft on rear‑ or all‑wheel‑drive vehicles. The 2009 Vitz/Yaris in FWD form doesn’t use a prop shaft at all, it sends drive straight to the front wheels via short CV shafts, so there’s nothing mid‑car that needs a centre support. This layout also keeps weight down, reduces frictional losses, and frees up cabin space — handy on a compact hatch.

There is one edge case worth noting: some Japan‑market 4WD Vitz variants (e.g., NCP95) use a propeller shaft to the rear differential. Those specific models may have a centre support and bearing assembly shown in the EPC. For Australia and New Zealand, where the 2009 Yaris range is FWD, a centre-bearing isn’t part of the driveline.

If an owner is chasing a mid‑car vibration or droning noise on a FWD 2009 Vitz/Yaris, the usual suspects are:

• Front CV joints or inner tripod joints under load
• Front wheel bearings humming with road speed
• Engine or transmission mounts causing a shudder on take‑off
• Tyre defects or uneven wear

Popular questions

Does a 2009 Toyota Vitz/Yaris have a centre-bearing?
For the common FWD models, no. There’s no propeller shaft, so there’s no centre support bearing to service or replace. If it’s a rare JDM 4WD variant, a centre support on the prop shaft may be used.

What’s causing a humming noise if there’s no centre-bearing?
Most often it’s a front wheel bearing, tyre roar, or a worn inner CV joint. Noise that changes with road speed (not engine revs) points to tyres or wheel bearings, a shudder under load points more to CV joints or mounts.

How can someone confirm their Vitz/Yaris variant?
Check the model code on the build plate or registration details. FWD codes like KSP90/SCP90/NCP91 won’t have a prop shaft. A 4WD code such as NCP95 indicates a rear driveline, which can include a centre support arrangement.
