Parts for your 1996 Toyota Caldina-Centre bearing

1996 Toyota Caldina centre-bearing — what’s fitted and what isn’t

Based on Toyota technical references, a centre-bearing (centre support bearing for a two-piece propeller/drive shaft) is not used on front‑wheel‑drive 1996 Toyota Caldina models (e.g., ST190/ST191). Those cars have a transaxle driving short front half‑shafts only, so there’s no long tailshaft to support. In contrast, 4WD/AWD Caldina variants of this era (commonly coded ST195G) do use a two‑piece propeller shaft with a rubber‑mounted centre support bearing. This fitment is shown in Toyota’s Electronic Parts Catalog (EPC) for ST195G in the Propeller Shaft section and described in the Toyota workshop manual driveline chapter for the T190‑series 4WD models.

Why FWD Caldinas don’t use a centre-bearing: without a rear differential there’s no propeller shaft, so there’s nothing mid‑span to support. The front shafts are short, directly supported by the transaxle and wheel hubs, so a centre-bearing simply isn’t part of the design.

For owners of 1996 Caldina 4WD (ST195G), the centre-bearing’s job is to steady the two‑piece prop shaft between the transfer and rear diff. It keeps the shaft aligned under load, cushions vibration through a rubber carrier, and helps the driveline run smooth at highway speeds. When the bearing or its rubber mount wears, tell‑tales include a droning or humming that rises with road speed, a shudder on take‑off, or a thump/clunk on lift‑off.

Service advice is simple: inspect it whenever the car’s on a hoist. Check the rubber carrier for cracks, sagging or separation, and try to rotate the shaft by hand to feel for roughness or excess play at the bearing. The bearing itself is usually sealed and not serviceable, replacement is the fix when it’s noisy or loose.

Replacement is a straightforward but precise job. The prop shaft comes out as an assembly, mark yokes and flanges so everything goes back in the same orientation to maintain balance. A press or puller is typically required to remove the old bearing from the shaft. It’s good practice to:

• Replace the carrier/bearing as a unit and inspect universal joints at the same time.
• Torque flange bolts to workshop specs and align marks exactly as removed.
• Check mount bushes and driveline angles after refit, then road‑test for vibration between 40–80 km/h.

Quality matters here. A genuine or reputable aftermarket bearing with a robust rubber carrier will outlast bargain options, especially on New Zealand and Australian roads where mixed surfaces can load the driveline. There’s no fixed kilometre interval, condition‑based replacement is the go. If vibration persists after fitting, have the shaft balance checked.

Technical sources referenced: Toyota Electronic Parts Catalog (Caldina ST195G, Driveline/Propeller Shaft illustration listing a centre support bearing), Toyota T190‑series 4WD workshop manual (Drivetrain – Propeller Shaft inspection/replacement procedures), mainstream bearing and driveline catalogues that list a centre support/carrier bearing for ST195 4WD applications.

Popular questions about 1996 Toyota Caldina centre-bearing

How can someone tell if their Caldina’s centre-bearing is failing?
Common signs are a low‑pitch hum or droning that follows road speed, a take‑off shudder, or a thump when lifting off the throttle. On a hoist, excessive movement in the rubber carrier or roughness when spinning the shaft by hand are red flags.

Can the centre-bearing be replaced on its own, or is a whole prop shaft needed?
On the 4WD ST195G it’s typically replaceable on its own. The shaft must be removed and the bearing pressed off/on. Many workshops will renew the carrier rubber and inspect U‑joints at the same time to save future labour.

Do FWD Caldinas (ST190/ST191) have a centre-bearing at all?
No. Front‑wheel‑drive models don’t have a rear prop shaft, so there’s no centre-bearing in their driveline design.
