Parts for your 2010 Subaru Exiga-Universal joints

2010 Subaru Exiga universal joints (U‑joints) – what they do and how to look after them

Universal joints are absolutely relevant on the 2010 Subaru Exiga. The Subaru Exiga (YA series) Factory Service Manual identifies a two‑piece propeller shaft with cross‑type universal joints and a centre support bearing in the driveline, and the Subaru electronic parts catalogue lists the universal‑jointed intermediate steering shaft for this model year as well. Those technical sources confirm the Exiga uses U‑joints in both the drivetrain (prop shaft) and the steering column.

On the Exiga’s Symmetrical AWD, the propeller shaft U‑joints let the shaft transmit drive from the transmission to the rear differential while dealing with suspension and angle changes. When healthy, they run quiet and smooth. When worn, they can cause clunks on take‑off, a shudder under load, or a droning vibration around highway speeds. Left too long, a failing U‑joint can damage the centre bearing, flanges, or even the gearbox output and rear diff input.

Most Subaru OE prop shafts from this era use sealed, non‑greaseable, staked‑in U‑joints. That means routine greasing isn’t part of normal servicing, and once there’s play or binding, the usual fix is to replace the complete propeller shaft assembly. A driveline specialist can sometimes rebuild the original shaft by machining out the staked joints and fitting circlip‑type serviceable U‑joints, but that’s a workshop decision based on shaft condition and cost.

Good servicing practice for a 2010 Exiga includes an underbody check every 20,000 km or during major services:

• Listen and feel for a clunk on take‑off or shift transitions.
• Check for rust‑coloured dust at U‑joint caps, looseness in the yokes, or any notchiness when the shaft is rotated by hand (with the vehicle safely raised).
• Inspect the centre support bearing rubber for cracks and the steering intermediate shaft U‑joints for stiffness or corrosion.

If replacement’s on the cards, mark the flanges so the new or rebuilt shaft can be installed in the same orientation to preserve phasing. Use new self‑locking hardware where specified, apply thread locker if called for, and torque to the factory spec from the service manual. After fitting, a road test to confirm the vibration is gone is essential, if there’s still a shake, consider tyre balance, wheel alignment, or centre bearing condition.

For owners who tour long distances or tow, keep an ear out for early signs and have the driveline inspected proactively—catching a tired U‑joint early keeps the rest of the AWD system happy and the Exiga cruising smoothly.

Popular questions

How long do U‑joints typically last on a 2010 Exiga?
With normal city and highway use, many see well over 150,000 km before any fuss. Vehicles that tow, carry heavy loads, or regularly drive on corrugated roads can see earlier wear. Listening for new clunks or feeling a fresh vibration at speed is the best early warning.

Can the Exiga’s prop shaft U‑joints be greased or replaced individually?
The factory joints are sealed and staked, so there are no grease nipples and Subaru supplies the propeller shaft as a complete assembly. A driveline shop may be able to rebuild the original shaft with serviceable circlip‑type U‑joints if the tube and yokes are in good nick.

Is a vibration always the U‑joints, or could it be something else?
Not always the U‑joints. Tyre balance, a tired centre support bearing, bent wheels, or even engine/trans mounts can mimic U‑joint symptoms. A proper inspection—checking joint play, bearing condition, and tyre/wheel balance—pins it down quickly.
