Parts for your 1994 Toyota Caldina-Centre bearing

1994 Toyota Caldina centre bearing — does this model use one?

Short answer: only the 4WD versions do. According to Toyota’s Electronic Parts Catalogue for the T190-series Caldina (model codes around 1992–1997) and the Toyota Repair Manual/Drivetrain sections for the same platform, the 2WD ST190G uses a front transaxle with left/right driveshafts and no propeller shaft, so there’s no centre support bearing fitted. The 4WD ST195G has a two-piece propeller (tail) shaft running to the rear differential, and Toyota lists a “bearing assy, centre support” for that shaft. Toyota’s New Car Features (NCF) for the T190 platform also describes the full-time 4WD layout with a multi-piece propeller shaft supported mid-span by a carrier (centre) bearing.

• 2WD (e.g., ST190G): no centre bearing — not applicable
• 4WD (e.g., ST195G): centre bearing fitted on the propeller shaft

For anyone chasing the part on a 2WD Caldina: you might be thinking of the intermediate (carrier) bearing on the long front driveshaft — that’s a different item entirely from a propeller-shaft centre bearing.

If you’ve got a 1994 Caldina 4WD, here’s what matters about its centre bearing. The centre bearing sits on the two-piece tailshaft and keeps the whole lot steady as torque loads change, cutting down vibration and protecting the universal joints, diff, and gearbox. It’s basically the midpoint support and vibration damper, with a rubber-mounted carrier that soaks up movement while the bearing itself lets the shaft spin freely. When it starts to go, owners usually notice a low-speed rumble or a droning vibration at highway speeds, sometimes a clunk on take-off, and cracked rubber around the carrier.

Good servicing on a 1994 Toyota Caldina centre bearing is dead simple: inspect it any time the wagon’s on a hoist, at least every 20,000 km or annually. Look for perished rubber, off-centre sag, or play in the support, if the shaft’s out, spin the bearing and feel for roughness. On replacement, always mark the flanges and yokes so the tailshaft goes back in phase and balanced as before. Support the exhaust and heat shields, drop the centre section, press out the old bearing, press in a quality replacement, and refit the carrier bracket without pre-loading the rubber. If there’s still vibration after a fresh bearing, check the tailshaft balance, uni joints, engine and diff mounts, and tyre condition. Most centre bearings last well past 150,000 km, but heavy towing, rough roads, and lifted suspension can shorten their life. And for the 2WD crowd: you won’t have this part at all, so any driveline vibration is more likely tyres, inner CVs, or the right-hand intermediate shaft bearing rather than a centre bearing.

• Common symptoms to watch:
  • Vibration under load or at 50–100 km/h
  • Dull drone/rumble through the floor
  • Clunk on take-off, carrier rubber visibly cracked or sagging

FAQs

Do all 1994 Toyota Caldinas have a centre bearing?
No. Only the 4WD (e.g., ST195G) uses a centre bearing on the propeller shaft. The 2WD (ST190G) doesn’t have a tailshaft at all, so there’s no centre bearing to service. Don’t confuse this with the intermediate bearing on the long front driveshaft in some 2WD layouts — that’s a separate part.

What are the tell-tale signs the centre bearing needs replacing?
A droning vibration at cruising speeds, a shake on acceleration, a clunk as drive takes up, or obvious cracking and sag in the rubber carrier. If the tailshaft is out, any roughness or notchiness when spinning the bearing by hand is another giveaway.

Is it safe to keep driving with a noisy centre bearing?
Not ideal. A failing centre bearing can hammer the uni joints and stress the gearbox and diff mounts. Short trips might be manageable, but it’s wise to sort it promptly to avoid larger driveline damage and bigger repair bills.
