Parts for your 2007 Toyota Caldina-Wheel hubs

2007 Toyota Caldina wheel-hubs: what they do and when to service them

Technical references confirm wheel-hubs are absolutely relevant to the 2007 Toyota Caldina. The Toyota Electronic Parts Catalogue (EPC) for the Caldina T24# series (2002–2007) lists both “Hub Sub-Assembly, Front Axle” and “Rear Axle Hub & Bearing Assembly,” and the Toyota Repair Manual includes procedures under Front Axle Hub and Rear Axle Hub for these models (including FWD AZT/ZZT variants and AWD ST246). That means the vehicle is fitted with hub assemblies front and rear.

On this Caldina, the wheel-hub mounts the wheel to the car and supports the vehicle’s weight via a sealed bearing. It provides the wheel studs for the nuts, carries the brake rotor, and interfaces with the drive shaft splines on driven wheels. Many assemblies also integrate the ABS wheel speed pickup or tone ring. Depending on variant, the design may be a bolt-on sealed hub unit, or a hub with a bearing pressed into the steering knuckle—both are standard Toyota approaches covered in the factory manual.

• Typical symptoms of a failing hub/bearing: a humming or growling noise that rises with road speed, play felt at the wheel (12-and-6 o’clock test), ABS warning light or erratic speed readings, uneven tyre wear, or a hot hub after driving.
• Service checks: during routine servicing or tyre rotations (around every 10,000–20,000 km), inspect for noise, roughness when spinning, and any free play. Confirm the ABS sensor lead and connector (where fitted) are intact.

As these are sealed bearings, routine greasing isn’t required. Once roughness or play shows up, replacement is the go. Quality replacement is important—match the assembly to the car’s build and ABS specification. The factory procedure calls for correct hub/axle nut torque and careful seating, over- or under-torque can shorten bearing life. Where the bearing is pressed into the knuckle, a proper press and supports are needed to avoid damage, where it’s a bolt-in hub unit, penetrating fluid and careful fastener removal helps in corrosive environments.

AWD ST246 models use driven hubs front and rear with splined centres, FWD variants have driven fronts and non-driven rears. Parts are not universally interchangeable across variants, so using the VIN or exact model code when ordering is wise. Regular checks keep things quiet, protect tyres and brakes, and prevent unwanted ABS dramas.

Popular questions about 2007 Toyota Caldina wheel-hubs

Are AWD and FWD Caldina hubs the same?
They differ. AWD ST246 uses splined, driven hubs at the rear as well as the front, and ABS configurations can vary. Always match by VIN/model code to get the right flange pattern, ABS pickup, and spline.

How long do the hubs/bearings typically last?
On well-kept Caldinas, many see 150,000–250,000 km or more. Rough roads, heavy loads, water intrusion, and incorrect wheel/axle nut torque can shorten that span. Regular inspections help catch wear early.

Can a noisy hub cause other damage?
Left too long, excessive hub play can affect brake rotor alignment, trigger ABS faults, and accelerate tyre wear. On driven wheels, it can also stress CV joints and seals. Replacing a noisy hub promptly avoids compounding costs.
