Parts for your 2006 Toyota Highlander-Driveshafts

2006 Toyota Highlander Driveshafts

Yes, driveshafts are relevant to the 2006 Toyota Highlander. Toyota’s New Car Features (NCF) and Electronic Parts Catalogue (EPC) show all 2006 Highlander/Kluger variants use front drive shafts (CV axles). AWD petrol models (e.g., MCU28) also have a propeller shaft running to the rear differential. The 2006 Highlander Hybrid (MHU38), however, uses an electric rear motor (e‑AWD) and therefore has no mechanical propeller shaft to the rear. That layout is also described in the Toyota Repair Manual and NCF for the hybrid system.

On vehicles fitted with them, the driveshafts do the heavy lifting of getting torque to the wheels smoothly and reliably. Up front, the CV axles transmit drive from the transaxle to the hubs, allowing full steering and suspension travel without drama. In AWD petrol models, the centre propeller shaft links the transfer to the rear diff, using universal joints and a slip section (plus a centre support bearing on two‑piece shafts) to handle length changes and angles as the vehicle moves.

As part of routine servicing, it’s smart to give the driveshafts a proper once‑over. At each service interval, check CV boots for cracks or splits, look for flung grease, and listen for clicking on full lock. On AWD petrol models, inspect the prop shaft for play in the uni joints, wear in the centre bearing, and any dents or missing balance weights. A shudder under load or a humming/vibration at open‑road speeds can point to a worn joint or out‑of‑balance shaft. Keeping the transaxle and diff oils fresh helps protect the whole driveline, too.

Replacement is straightforward for a trained tech and worth doing promptly if there’s damage. For CV axles, replace any leaking or split boots early to save the joint
