Parts for your 2004 Toyota Caldina-Wheel hubs

2004 Toyota Caldina wheel hubs

Wheel hubs are absolutely used on the 2004 Toyota Caldina. Technical references including the Toyota Electronic Parts Catalogue (EPC) for ZZT/AZT/ST246 series (2002–2007) and the Toyota Repair Manual list front and rear hub or hub-and-bearing assemblies across both FWD variants and the GT-Four AWD (ST246). These assemblies locate the wheel, support the brake rotor/drum, house the bearing, and—on driven axles—transfer torque through the splined drive shaft while feeding ABS signals via an integrated tone ring or encoder.

On a 2004 Caldina, the hub’s job is twofold: keep the wheel tracking straight and smooth, and handle the forces of braking, cornering and (where applicable) drive. The front hubs on both FWD and AWD models are driven, the rear may be a bolt-in sealed hub-and-bearing unit on many trims, while some variants use a press-in bearing with a separate hub. Either way, it’s a critical piece of kit for safe, quiet motoring.

For servicing, a good workshop will check for play and noise every service interval. With the vehicle safely raised, any roughness, a low-speed rumble that gets louder with road speed, or play when rocking the wheel at 12 and 6 o’clock points to bearing wear within the hub. They’ll also inspect for ABS faults from damaged encoder rings, corrosion on the hub-to-rotor face, and wheel stud condition.

• Symptoms that suggest hub attention: humming or growling that changes with speed or when swerving gently, ABS warning lights, uneven tyre wear, or heat around the wheel after a drive.
• Replacement pointers: use quality parts matched to FWD vs GT-Four AWD, clean mating surfaces, replace single-use fasteners (axle nuts/hub bolts) where specified, and torque everything to the factory spec from the Toyota manual.
• Post-fit checks: road test for noise, confirm ABS operation, and recheck wheel-nut torque after 50–100 km.

Because most Caldina hubs use sealed bearings, there’s no routine greasing—once they wear or get noisy, replacement is the go. In coastal Aussie and Kiwi conditions, corrosion can seize components, so penetrating fluid, patience, and the right pullers or a press make the job smoother. If unsure, a professional with the Toyota service data will sort it without drama.

Popular questions

What are the signs a 2004 Caldina’s wheel hub or bearing is failing?

Common clues are a steady humming or growling that rises with speed, a droning that changes when veering left or right, light vibration through the floor, or an ABS light if the encoder ring has copped damage. You might also feel looseness when rocking the wheel at 12 and 6 o’clock with the car lifted.

Left too long, heat build-up can escalate and affect the brake rotor or ABS sensor, so it’s best to get onto it early.

Are FWD and GT-Four AWD Caldina hubs the same?

Not typically. The GT-Four AWD uses different front and rear hub assemblies to suit its driveline and brakes. FWD models often have bolt-in rear hub-and-bearing units, while AWD rears are specific to the multi-link and driveshaft setup. Always match parts to the VIN and drivetrain.

Do Caldina wheel hubs need greasing during servicing?

No. Most 2004 Caldina hubs use sealed bearings that aren’t serviceable. The smart move is periodic inspection for noise and play, keeping the hub and rotor faces clean, and replacing the assembly if wear shows up. Grease is only for related components where the Toyota manual specifies it, not for sealed hub bearings.
