Parts for your 2006 Toyota Kluger-Wheel hubs

2006 Toyota Kluger wheel hubs — what they do and when to service them

Wheel hubs are absolutely used on the 2006 Toyota Kluger. Technical references such as the Toyota Electronic Parts Catalogue for the XU20 Kluger list the Front Axle Hub Sub‑Assembly (PNC 43502) and Rear Axle Hub & Bearing Assembly (PNC 42450). The Toyota Repair Manual for Kluger/Highlander (XU20) also details hub and bearing inspection and replacement procedures for front and rear axles, including ABS encoder integration. These sources confirm the vehicle is fitted with wheel hubs on all four corners.

On a 2006 Kluger, the wheel hub is the bit that the wheel bolts onto, and it carries the wheel bearing that lets the wheel spin smoothly. It also provides the mounting face for the brake rotor and, on ABS-equipped models, houses the magnetic encoder that the wheel speed sensor reads. Without a healthy hub and bearing, it’s all groans, vibration and vague steering — not ideal for the school run or a long Kiwi/Aussie road trip.

Up front, the Kluger typically uses a pressed-in bearing seated in the steering knuckle with the hub pressed through it. Out back, many variants use a bolt-in hub and bearing assembly. In both cases, the bearing is sealed — there’s no greasing them during a normal service. Instead, the smart play is regular inspection during tyre rotations and brake checks.

• Tell-tale signs it’s time: a humming that rises with speed, a rumble when cornering, ABS light with no obvious sensor damage, or detectable play when rocking the wheel at 12 and 6 o’clock.
• Good habits: keep wheel nuts torqued correctly, avoid kerb strikes, and address brake drag promptly to prevent heat soaking the bearing.

When replacement is due, a front hub/bearing job usually needs a press and proper support blocks to avoid damaging the new bearing. The rear assembly, where fitted, typically bolts on. Replacing the axle nut, cleaning mating faces, and torquing everything to spec matters — over-tightening or under-tightening can shorten a bearing’s life. It’s also worth scanning the ABS system afterwards, as the encoder ring is part of the bearing on many Klugers.

Most owners will see well over 100,000 km from factory hubs, but usage, loads, and road conditions make a difference. Catching early noise and dealing with it quickly keeps tyres, brakes and fuel economy in better shape.

Popular questions about 2006 Toyota Kluger wheel hubs

How can someone tell if a Kluger hub or bearing is failing?
They’ll often hear a low, steady humming that changes with road speed and may get louder when loading one side of the car in a turn. On a lift, there may be roughness when spinning the wheel by hand, or noticeable play when rocking the wheel at the top and bottom. An ABS light with a clean sensor can also point to a failing bearing encoder.

Are the front and rear hubs the same on a 2006 Kluger?
No. Fronts generally use a pressed-in bearing with a separate hub, while many rears are a bolt-on hub and bearing assembly. AWD and 2WD variants can differ, so checking the VIN against the Toyota EPC is the safest way to match parts.

Can the bearing be serviced, or does the whole hub need replacing?
The bearings are sealed. On the front, technicians usually press out the old bearing and hub and press in new components. On the rear (where a bolt-in unit is used), the full hub/bearing assembly is typically replaced as one piece.
