Parts for your 2005 Toyota Ist-Centre bearing

2005 Toyota ist centre-bearing — is it actually a thing?

Short answer: for most 2005 Toyota ist models, a centre-bearing isn’t used. The first‑gen ist (XP60 series — frame codes NCP60/NCP61) is a front‑wheel‑drive hatch built on the Vitz/Yaris platform, which means there’s no rear propeller shaft to support. Per Toyota’s Electronic Parts Catalogue (EPC) and the factory repair manual for NCP60/NCP61, the driveline consists of a transverse transaxle and two front half‑shafts only, there’s no listing for a propeller shaft assembly or a centre support bearing on those FWD models. Major aftermarket catalogues reflecting the same platform (e.g., Scion xA equivalent) also show the centre support bearing as “not applicable”.

Why isn’t a centre-bearing used? A centre-bearing’s job is to support a long, multi‑piece propeller shaft on rear‑ or all‑wheel‑drive vehicles, keeping the shaft aligned between the gearbox and rear differential. The FWD ist simply doesn’t have that shaft — the engine and gearbox sit up front, driving the front wheels via short CV shafts, so there’s nothing mid‑car that needs a support bearing.

There is one important exception worth noting for Aussie and Kiwi buyers of JDM imports: the NCP65 4WD variant of the ist does exist in Japan. On those AWD cars, Toyota’s EPC and repair manual sections for Propeller Shaft list a “centre support bearing” (often called a prop shaft centre bearing). If your ist is the NCP65 4WD, a centre-bearing is relevant and serviceable.

Not sure which one you’ve got? Check the frame code on the build/compliance plate or your rego/insurance paperwork:

• NCP60/NCP61 = FWD, no centre-bearing.
• NCP65 = 4WD, prop shaft fitted, centre-bearing applies.

For owners of the 4WD NCP65, common signs of a tired centre-bearing include a droning or humming that rises with road speed, a shudder on take‑off, and a thump on overrun. Inspection involves checking the rubber carrier for cracking or sag, and feeling for roughness or play at the bearing. Replacement typically means removing the prop shaft, marking flange orientations, swapping the bearing and carrier, then refitting to the correct torque. Most U‑joints on these shafts are sealed, so regular greasing isn’t applicable, focus on visual checks at service intervals and replace the bearing once noise or play appears rather than waiting for a full‑on vibration.

Popular questions about 2005 Toyota ist centre-bearing

Does a 2005 Toyota ist have a centre-bearing?

Most don’t. The common FWD models (NCP60/NCP61) have no prop shaft, so there’s no centre-bearing fitted. Only the 4WD NCP65 variant uses a propeller shaft with a centre support bearing.

How can someone tell if their 2005 ist needs a centre-bearing?

Check the frame code. If it’s NCP65 (4WD), a centre-bearing is part of the driveline. If it’s NCP60 or NCP61 (FWD), a centre-bearing doesn’t apply to the vehicle.

What noises point to a failing centre-bearing on the 4WD ist?

Listen for a mid‑car hum or drone that increases with speed, a take‑off shudder, or a dull thump during on‑off throttle. Those symptoms warrant a closer look at the prop shaft centre-bearing and carrier.
