Parts for your 2006 Toyota Highlander-Universal joints

Universal joints on a 2006 Toyota Highlander (Kluger): AWD models only

Based on technical references — Toyota’s Highlander/Kluger 2001–2007 Repair Manual (Drivetrain/Axle – Propeller Shaft), the Toyota Electronic Parts Catalogue, and the Haynes Highlander/RX manual — universal joints (U‑joints) are fitted only to 2006 Highlander/Kluger AWD models. Those vehicles use a two‑piece propeller shaft with a centre support bearing and U‑joints. Front‑wheel‑drive (2WD) models don’t have a prop shaft, so no U‑joints, they run constant velocity (CV) joints at the front instead. So universal joints are relevant for AWD 2006 Highlanders/Klugers, and not applicable to 2WD versions.

On AWD 2006 Highlanders/Klugers, the universal joints sit on the propeller shaft that sends drive to the rear differential. Their job is to let the shaft transmit torque while handling suspension movement and angle changes between the gearbox and rear end. When U‑joints are healthy, the driveline feels smooth and quiet, when they’re worn, drivers may notice a thud on take‑off, a shudder under load, or a vibration around 60–100 km/h.

Toyota typically supplies the propeller shaft as an assembly, and the factory U‑joints are often non‑greasable. That means routine maintenance is mostly about inspection rather than lubrication. As part of regular servicing, it’s smart to check for red/brown rust powder at the bearing caps, split seals, looseness in the joint, and play at the slip yoke. Also listen for clunks when shifting between drive and reverse, and feel for vibration on road test. Don’t forget the centre support bearing while you’re under there.

If replacement is needed, many workshops follow Toyota’s approach and fit a complete prop shaft assembly to maintain balance and phasing. A reputable driveline specialist can also rebuild the shaft with quality serviceable U‑joints. Either way, mark the flanges before removal to keep the phasing correct, use new hardware where specified, and torque to spec with threadlocker. After refit, a quick road test to check for vibration is worth its weight in gold. For drivers who tow or see lots of gravel and water crossings, more frequent inspections are a good shout — early attention to a noisy U‑joint can save a centre bearing and rear diff down the track.

Note: 2WD 2006 Highlanders/Klugers don’t use U‑joints at all, their driveline uses CV joints only, so any clunk or vibration up front is more likely CV‑related.

• Common symptoms: clunk on take‑off, shudder under load, vibration at highway speeds, visible rust dust at caps
• Service tip: inspect U‑joints and centre support bearing every major service, especially on AWD vehicles that tow

Popular questions

Does a 2WD 2006 Highlander/Kluger have universal joints?
No. The 2WD version has no propeller shaft, so no U‑joints. It uses front CV shafts only. Any front‑end clicking or vibration is typically a CV joint, wheel bearing, or tyre issue, not a U‑joint.

What are the signs the AWD Highlander/Kluger U‑joints are worn?
Look for a clunk when shifting between drive and reverse, a shudder on take‑off, or a steady vibration at 60–100 km/h. Underneath, rust powder around bearing caps or any looseness at the joints points to wear.

Can the U‑joints be greased or do you have to replace the whole shaft?
Factory U‑joints are commonly non‑greasable. Many shops replace the complete prop shaft to preserve balance, but a driveline specialist can rebuild the shaft with quality serviceable U‑joints if preferred.
