Parts for your 2005 Toyota Highlander-Universal joints

2005 Toyota Highlander universal-joints

Based on Toyota’s factory repair information (Drivetrain/Axle – Propeller Shaft section for 2001–2007 Highlander), the Toyota Electronic Parts Catalogue, and independent manuals such as Haynes/Chilton, the 2005 Toyota Highlander fitted with All-Wheel Drive (AWD) uses universal joints on the rear propeller shaft, along with a centre support bearing. Front-Wheel Drive (FWD) Highlanders do not have a rear prop shaft, so universal-joints are not used on those models.

On AWD 2005 Highlanders, universal-joints (U-joints) sit at either end of the propeller shaft linking the transaxle/transfer assembly to the rear differential. Their job is to let the shaft transmit torque smoothly even as the angles change with suspension movement. That bit of compliance keeps the driveline quiet and the ride tidy, especially on rough Kiwi and Aussie roads.

From the factory, the Highlander’s prop shaft uses sealed, non-greaseable joints, Toyota supplies the shaft as a complete assembly rather than listing the U-joints as separate service parts. Plenty of driveline specialists can rebuild one with quality serviceable joints, but for dealer-style servicing the usual fix for a worn joint is replacement of the whole prop shaft. During routine servicing, it’s smart to inspect the rear shaft for free play, rust-coloured dust at the bearing caps, torn dust shields, and to check the centre support bearing rubber for cracking.

Common signs the universal-joints are on the way out include a chirp or squeak at low speeds that comes and goes with vehicle motion, a thump on take-off or when shifting from reverse to drive, and a buzz or vibration around 60–100 km/h that feels like it’s under the floor. If any of those crop up, get it checked promptly—if a joint lets go, it can take other components with it.

• Inspection: every 20,000–30,000 km or at each service, check for play and leaks, there are no grease nipples on the OEM joints.
• Replacement: mark the flange relationships before removal to preserve balance, torque the flange bolts to spec and road test for vibrations. If the centre bearing rubber is tired, replace it at the same time.
• Rebuild vs replace: complete shaft replacement is straightforward, a specialist rebuild can add greaseable joints and may be more economical.

For owners of FWD Highlanders, there’s no rear prop shaft and no universal-joints to maintain, which is why this part isn’t relevant on those vehicles—front drive is handled by constant-velocity (CV) shafts at the wheels instead.

Does every 2005 Highlander have universal-joints?

No. Only AWD models have them, fitted on the rear propeller shaft. FWD versions don’t use a rear driveshaft, so there are no universal-joints in the driveline. If unsure, check for a rear differential and a shaft running down the middle of the vehicle—if that’s there, it’s AWD.

Can the Highlander’s universal-joints be greased or replaced individually?

From the factory, they’re sealed and non-greaseable. Toyota generally supplies the prop shaft as a complete assembly. A driveline shop can often press out the staked joints and fit quality replacements, sometimes adding greaseable joints for easier future maintenance.

What are the warning signs of a failing U-joint, and is it safe to keep driving?

Listen for squeaks at low speed, feel for clunks on take-off, and watch for vibrations at highway speeds. Continued driving with a failing joint risks losing the shaft or damaging the transfer, diff, or exhaust. It’s best to book it in as soon as symptoms appear.
