Parts for your 2002 Toyota Caldina-Universal joints

2002 Toyota Caldina universal joints (uni joints): what’s fitted and how to look after them

Technical references including Toyota’s New Car Features for the ST246/ZZT241 series, the Toyota Repair Manual (Drivetrain section, 2002–2007 Caldina), and the Toyota Electronic Parts Catalogue confirm the following: front‑wheel‑drive 2002 Caldina models use constant‑velocity (CV) joints on the front driveshafts and do not use universal joints, all‑wheel‑drive models (e.g., ST246W/CT216W) have a rear propeller shaft that uses universal joints. So, uni joints are relevant to AWD Caldinas, but not to FWD variants.

For owners of AWD 2002 Caldinas, the universal joints on the prop shaft quietly handle the changing angles between the gearbox and the rear differential as the car moves, turns, and the suspension works. They keep torque flowing smoothly to the rear wheels without binding. When they’re healthy, you’ll barely know they exist, when they’re tired, you’ll hear or feel them before you see trouble.

Servicing advice for AWD Caldina uni joints:

• Inspection intervals: check every 20,000–30,000 km or at each major service, especially if the car tows, sees rough roads, or spends time on the beach.
• What to look for: any play at the caps, rust bleeding from the bearing seals, dry or seized movement, and missing retaining clips. On the road, a failing uni joint often shows up as a shudder on take‑off, a vibration that follows road speed, or a metallic clunk when shifting from drive to reverse.
• Greasing: many Toyota prop shaft uni joints of this era are sealed (no nipples) and are non‑greasable. If your replacement joints have grease nipples, a quality lithium‑moly grease works well, wipe fittings clean before and after greasing.
• Replacement tips: mark the prop shaft flanges before removal to keep balance and phasing correct. Support the shaft to avoid damaging the slip yoke or centre bearing. Press out the old joint carefully to avoid deforming the yoke ears. If there’s any doubt about balance or the centre bearing condition, address both while the shaft is out.
• Fasteners and torque: use new flange bolts where specified by Toyota and torque to spec from the repair manual. Re‑check for vibrations after a test drive.

A well‑kept uni joint keeps the AWD system smooth and quiet and protects the gearbox, centre bearing, and rear diff from extra stress. If the car is FWD only, focus checks on the front CV joints and boots instead—those do the equivalent job up front.

Popular questions

Does a 2002 Caldina have universal joints?
FWD models don’t—they use CV joints on the front driveshafts. AWD models do, on the rear propeller shaft linking the transmission to the rear diff. That setup is confirmed by Toyota’s Repair Manual, New Car Features, and the EPC listings for the ST246W prop shaft assembly.

What are the signs a Caldina uni joint is failing?
Look for a take‑off shudder, a speed‑related vibration, a clunk when going from drive to reverse, or rust staining at the bearing caps. Any free play when twisting the prop shaft by hand is a red flag.

Can the Caldina’s uni joints be greased?
Many factory joints are sealed and non‑greasable. If your replacement joints include grease nipples, give them a light pump of lithium‑moly grease at major services. If sealed joints feel rough or loose, replace rather than attempt to lubricate.
