Parts for your 2013 Subaru Exiga-Universal joints

2013 Subaru Exiga universal joints (U‑joints): what they do and how to look after them

Drawing on the Subaru Exiga (YA series) factory service manual’s Propeller Shaft section and the Subaru FAST electronic parts catalogue, the 2013 Subaru Exiga is fitted with universal joints in its two‑piece propeller shaft. These U‑joints are sealed, non‑greasable items typically supplied as part of the complete propeller shaft assembly with a centre support bearing, which is how Subaru specifies service on many AWD models.

On the Exiga’s Symmetrical AWD driveline, the universal joints sit on the prop shaft connecting the transmission to the rear differential. Their job is to let the shaft articulate as the car moves and the suspension works, keeping torque delivery smooth even when the angles between components change. At the wheels, the Exiga uses constant‑velocity (CV) joints, but in the middle of the car the U‑joints handle the angle changes with minimal fuss.

Because the factory U‑joints are sealed, there’s no routine greasing. The smart play is regular inspection during scheduled servicing. A quick check for play at the joints, dried rust‑coloured dust, torn boots on nearby components, or a weeping centre bearing can save headaches. Many owners will notice early hints such as a light vibration on throttle at highway speeds, a clunk on take‑off, or a shudder when shifting from reverse to drive—classic signs the prop shaft U‑joints or centre bearing need attention.

If wear is found, Subaru’s official repair path is to replace the complete propeller shaft assembly rather than press out the staked U‑joints. In Australia and New Zealand, driveline specialists can often rebuild and rebalance an Exiga shaft with serviceable U‑joints, but that’s best left to a reputable shop with the right jigs and balancing gear. When fitting a new or rebuilt shaft, mark the flange positions, use new self‑locking hardware, torque to spec, and recheck for NVH on a road test.

Good habits help the U‑joints live a long life:

• Inspect at each service or at least every 20,000–30,000 km.
• Listen for clunks and feel for vibrations under load or on overrun.
• Check the centre support bearing and mounts while you’re there.
• Avoid deep water crossings where possible, if unavoidable, have the driveline inspected soon after.

Treated well, the Exiga’s U‑joints will rack up plenty of kilometres, keeping the family wagon smooth, quiet and happy on the open road.

Popular questions

Does the 2013 Subaru Exiga have U‑joints or only CV joints?

It has both. The wheel half‑shafts use CV joints, while the two‑piece propeller shaft running down the centre uses universal joints with a centre support bearing. The factory U‑joints are sealed and not intended for periodic greasing.

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

They’re sealed, so there’s no greasing interval. Instead, include a driveline inspection at regular services—roughly every 20,000–30,000 km—checking for play, vibration, clunks on take‑off and the condition of the centre bearing and flange bolts.

Can the U‑joints be replaced separately, or does the whole shaft need changing?

Subaru’s service literature specifies replacing the complete propeller shaft if a U‑joint is worn. However, many driveline specialists in AU/NZ can rebuild and rebalance the shaft with serviceable U‑joints. If choosing that route, use a trusted shop with proper balancing equipment.
