Parts for your 2006 Toyota Highlander-Centre bearing

2006 Toyota Highlander/Kluger centre-bearing: fitment, purpose, and service tips

Technical sources confirm that a centre-bearing (also called a centre support or carrier bearing) is used on 2006 Toyota Highlander/Kluger AWD models, but not on front-wheel-drive (2WD/FWD) versions. The Toyota Electronic Parts Catalogue (EPC) lists a centre support bearing within the propeller shaft assembly for AWD Highlander/Kluger of this generation, and the Toyota Repair Manual for the propeller shaft section details inspection and replacement procedures for the centre support. Major aftermarket catalogues (e.g., Dorman, Westar, and similar driveline suppliers) also list a carrier/centre support bearing specifically for 2001–2007 Highlander/Kluger AWD. So, the centre-bearing is relevant if the vehicle is AWD, it’s not present on FWD models because they have no rear propeller shaft.

On an AWD 2006 Highlander/Kluger, the centre-bearing supports the two-piece propeller shaft running from the transfer output to the rear differential. Think of it as a sturdy hanger in the middle of the shaft that keeps everything aligned, dampens vibration, and helps the universal joints live a long, quiet life. When it’s healthy, the driveline stays smooth under load and at highway speeds. When it’s crook, drivers may feel a shudder on take-off, a hum or vibration around 60–100 km/h, or hear a dull thud when getting on and off the throttle. A cracked rubber isolator or sloppy bearing play at the bracket are tell-tales during an underbody check.

As part of regular servicing, it’s smart to visually inspect the centre-bearing every service or two—say each 20,000–30,000 km—especially if the vehicle tows, sees rough roads, or runs larger tyres. Look for perished rubber, misalignment, or any contact marks on the shaft or heat shields. While there’s no routine lubrication for the sealed bearing itself, checking surrounding fasteners, mounts, and the condition of the prop shaft universal joints helps prevent knock-on issues.

Replacement is straightforward for a well-equipped workshop: mark the flanges for phasing, support the shaft, then drop it out as an assembly. Many technicians replace the centre-bearing on the bench, others opt for a complete propeller shaft if U-joints are non-serviceable or if the shaft shows wear. The bracket position should be set square, and all fasteners torqued to the factory spec from the Toyota Repair Manual. It’s good practice to use new self-locking nuts/bolts where specified and to re-check for vibration after a short road test. If a shake persists, also inspect engine, transmission, and rear diff mounts, as they can mimic centre-bearing symptoms.

• Common symptoms: take-off shudder, mid-speed vibration, clunk on throttle lift.
• Service tip: inspect every 20–30k km, replace if rubber is cracked or bearing has play.
• Fitment note: AWD only, FWD models do not have a centre-bearing.

Popular questions

How can someone tell if the centre-bearing is failing on a 2006 Highlander/Kluger?
They’ll often feel a vibration under load or around 60–100 km/h, notice a shudder on take-off, or hear a dull thud when getting on and off the throttle. Underneath, the rubber hanger may be cracked or the bearing may feel loose when the shaft is supported. It’s worth ruling out tyre/wheel issues and worn mounts too.

Can the centre-bearing be replaced separately, or does the whole prop shaft need to be swapped?
On many AWD Highlander/Kluger models, the centre-bearing can be replaced separately using quality aftermarket parts. However, if the universal joints are non-serviceable or the shaft shows wear or imbalance, replacing the complete propeller shaft assembly is often the better long-term fix. A driveline specialist can advise after inspection.

What sort of labour time and cost should be expected in Australia or New Zealand?
Labour typically ranges from about 1.5–3.0 hours depending on equipment and condition, plus parts. A standalone centre-bearing is usually the cheaper route, while a complete prop shaft costs more up front but can save time if multiple components are tired. Prices vary by region and brand, so a firm quote after inspection is best.
