Parts for your 2012 Subaru Exiga-Universal joints

2012 Subaru Exiga universal joints: what they do and how to look after them

Based on Subaru’s own technical literature for the Exiga YA-series (Driveline & Axle – Propeller Shaft section of the Subaru Service Manual) and the Subaru global service information used by dealers, the 2012 Subaru Exiga is fitted with universal joints. They’re on the two-piece propeller shaft that runs from the transmission to the rear differential, and there’s also a small universal joint in the steering intermediate shaft. The driveline U‑joints are a sealed, non-greaseable (staked) design and are treated by Subaru as part of the propeller shaft assembly.

On this AWD people-mover, the universal joints let the prop shaft transfer torque smoothly even as the suspension moves and the angles between gearbox and diff change. That flexibility keeps the Exiga’s ride civil and the cabin quiet, while protecting the gearbox and differential from binding.

For servicing, there isn’t a scheduled replacement interval for the Exiga’s U‑joints, but regular inspection is smart. At each service (or at least annually/15,000 km), a technician should check for axial or radial play in the joints, split seals, rust-coloured dust around the caps, and any roughness when the shaft is articulated by hand with the car safely raised. It’s also worth checking the centre support bearing and the prop shaft’s carrier mount at the same time.

Because Subaru uses staked, sealed U‑joints on the Exiga’s prop shaft, there are no grease nipples and no factory procedure to replace just the cross and bearings. If a joint is worn, noisy or seized, Subaru’s workshop guidance is to replace the complete propeller shaft assembly, then torque the flange bolts to the service manual spec and recheck for vibration on-road. Owners who prefer a more budget-friendly approach can talk to a driveline specialist, many can de-stake and rebuild the Exiga shaft with circlip-style serviceable joints, provided the yokes are within tolerance.

Common signs it’s time to act include:

• Driveline vibration that rises with road speed, especially between 60–100 km/h
• Clunk or shunt taking off or shifting between Drive and Reverse
• Chirping/squeak from under the floor that changes with speed
• Visible play or corrosion dust at a joint

Keeping tyres matched and pressures even, replacing worn engine/gearbox mounts, and ensuring the diff and trans output flanges are clean and aligned will all help the new joints (or shaft) stay happy and quiet for the long haul.

Popular questions about 2012 Subaru Exiga universal joints

Are the Exiga’s universal joints greaseable?

No. The factory prop shaft uses sealed, staked U‑joints with no grease nipples. When they wear, Subaru specifies replacing the whole propeller shaft assembly. Some driveline shops can rebuild the shaft with serviceable joints, but that’s a specialist job.

What’s the easiest way to spot a failing U‑joint on an Exiga?

Look for speed-related vibration, a clunk taking up drive, or a squeak that follows road speed. On a hoist, any notchiness when articulating the joint by hand, or rust-coloured dust at the bearing caps, are red flags.

How often should the Exiga’s U‑joints be inspected?

Have them checked at regular services (roughly every 10–15,000 km) and after any off‑seal use or water crossings. There’s no set replacement interval, condition-based inspection is the go.
