Parts for your 2010 Subaru Exiga-Universal joints

2010 Subaru Exiga universal joints: what they do and how to look after them

Based on Subaru’s factory literature for the YA‑series Exiga (MY2010)—notably the Service Manual sections Drivetrain/Propeller Shaft and Steering/Column, and the genuine parts catalogue—the 2010 Subaru Exiga does use universal joints. The AWD Exiga runs a two‑piece propeller shaft with cross‑type, staked (non‑greasable) universal joints and a centre support bearing, and it also uses a universal joint in the steering intermediate shaft. Those sources confirm the joints are part of the vehicle’s standard hardware.

On this model, the universal joints allow the prop shaft to transmit drive from the transmission to the rear differential even as the angles change with suspension movement. They keep the driveline smooth and happy, reducing vibration and letting the Exiga’s Symmetrical AWD put power down cleanly in everyday Kiwi and Aussie conditions. Up front, the axle shafts use CV joints, but the prop shaft relies on U‑joints for compact strength and proper phasing through its two‑piece layout.

From the factory, the Exiga’s prop shaft U‑joints are staked in. That means there are no grease nipples and, officially, the joints aren’t serviced separately—if a joint fails, Subaru specifies replacing the propeller shaft assembly. Some driveline specialists can rebuild or fit serviceable joints, but that’s outside standard dealer procedure.

Good servicing habits make a difference. During routine services (every 10,000–15,000 kilometres or 6–12 months), it’s smart to check for:

• Play at the prop shaft joints and at the steering intermediate shaft
• Rust staining (“fretting”) at bearing cup seals, or split boots on the steering joint
• Vibration on cruise or a shudder on take‑off, and a clunk when selecting Drive/Reverse
• Chirps or metallic squeaks at low speed that change with road speed

If replacement is needed, mark the flanges before removal so the new or rebuilt shaft goes back in the same orientation to protect balance. Keep the yokes in correct phase, renew any self‑locking fasteners as specified, and inspect the centre bearing and its rubber mount while you’re there. If an aftermarket serviceable prop shaft is fitted, add greasing of the joints and slip yoke to the normal service schedule.

Steering feel matters, too. Any notchiness or free play around centre can point to wear in the steering U‑joint, replacing the intermediate shaft restores direct feel and helps the Exiga track straight without fuss.

• Does the 2010 Subaru Exiga use universal joints or CVs on the prop shaft?
  The Exiga’s axle shafts use CV joints, but the propeller shaft uses cross‑type universal joints in a two‑piece layout with a centre bearing. That combo handles angle changes and keeps the driveline compact and well balanced for AWD duty.
• Can the Exiga’s prop shaft U‑joints be replaced on their own?
  From the factory they’re staked and not serviced separately—Subaru specifies replacing the whole prop shaft assembly. Some driveline shops can rebuild or fit serviceable joints, but that’s a specialist repair rather than standard OEM procedure.
• What are the common signs a universal joint is on the way out?
  Look for a low‑speed chirp or squeak, a clunk when taking up drive, or a vibration that worsens with speed. Rust bleed at the bearing cups and any detectable play at the joint are classic warning signs.
