Parts for your 2005 Toyota Caldina-Universal joints

2005 Toyota Caldina universal joints: what’s actually on the car?

Based on Toyota’s technical literature, universal joints (U‑joints) are fitted to 2005 Toyota Caldina models that are four‑wheel drive (often coded ST246W/AZT246W/ZZT246W). The Toyota Electronic Parts Catalogue (EPC) for the T24# Caldina generation lists a propeller shaft assembly with U‑joints and a centre support bearing for these AWD variants. The corresponding Toyota repair manual sections for the propeller shaft describe inspection of U‑joints and the centre bearing. By contrast, front‑wheel‑drive Caldina models (e.g., ZZT241/AZT241) do not have a propeller shaft and therefore have no driveline U‑joints, they use constant velocity (CV) joints on the front half‑shafts only.

Why no U‑joints on FWD versions? The FWD Caldina’s transaxle sends power straight to the front hubs via CV‑jointed shafts, which handle steering and suspension movement while maintaining constant rotational speed. Without a rear differential or prop shaft, there’s simply no place for a traditional U‑joint in the driveline on those models.

For AWD Caldina owners, the U‑joints on the prop shaft are there to transfer torque to the rear diff while allowing the shaft to operate at slight angles as the vehicle moves. They’re small, tough cross‑shaped couplings with needle bearings in each cap. When healthy, they run smooth and quiet, when worn, they can cause vibration, a clunk on take‑off or shift, and even a rumble at highway speeds. Many Toyota prop shafts of this era use sealed, non‑greaseable U‑joints, some markets may see serviceable replacements available, but often the factory approach is to replace the joint or, in some cases, the complete shaft if the joints are staked in.

As part of routine servicing, a good workshop will:

• Road test for driveline shudder or vibration, especially between 50–90 km/h under light throttle.
• Inspect the prop shaft for play at the U‑joints, looking for rust‑coloured dust around the caps and any notchiness when articulating by hand.
• Check the centre support bearing and rubber carrier for cracking or looseness.
• Verify flange bolts are tight and there’s no oil contamination from nearby seals.

If a U‑joint is worn, it should be replaced promptly to avoid damage to the prop shaft, diff pinion, or transmission output. Replacement practices vary: some shops press out staked joints and fit circlip‑style service joints, others follow Toyota’s guideline to replace the shaft assembly if it’s non‑serviceable. After replacement, a balance check of the shaft is wise to prevent residual vibration.

Tips for longer life? Keep an eye on any underbody impacts, renew torn dust shields promptly, and if you do water crossings or beach work, have the driveline inspected sooner rather than later. For serviceable joints, periodic greasing (as specified by the joint manufacturer) helps, but sealed OEM joints are typically maintenance‑free until they wear.

Popular questions about 2005 Toyota Caldina universal joints

How can someone tell if the Caldina’s U‑joints are failing?

Common signs include a dull clunk when shifting from reverse to drive, a vibration that comes in at certain speeds or under load, and a chirp or rumble that changes with road speed. Under the car, rust‑coloured dust at the bearing caps and any free play when twisting the prop shaft by hand are red flags. A mechanic can confirm by isolating tyres, checking backlash and articulating the joints off the vehicle.

Are the Caldina’s U‑joints serviceable, or is a full prop shaft replacement needed?

Many AWD Caldina prop shafts use staked, sealed U‑joints from factory. Depending on parts availability, a driveline specialist may fit replacement circlip‑type joints after machining out the stakes, or supply an exchange, balanced shaft. Some workshops follow Toyota’s guidance and replace the complete shaft if it’s deemed non‑serviceable. Local parts supply and the shaft’s overall condition usually determine the most cost‑effective route.

Is it safe to keep driving with a vibrating U‑joint?

Not recommended. A deteriorating U‑joint can escalate quickly, leading to severe vibration, damage to the centre bearing or flanges, and in extreme cases, shaft failure. Short trips to get it inspected are generally fine, but it’s best to book the repair promptly to avoid bigger bills and safety risks.
