Parts for your 2011 Subaru Exiga-Universal joints

2011 Subaru Exiga universal joints — what they do and how to look after them

Technical sources confirm the 2011 Subaru Exiga (YA-series) does use universal joints. The Subaru Exiga (YA) Service Manual (Driveline &, Axle — Propeller Shaft) describes a two‑piece propeller shaft with cross‑type universal joints and a centre support bearing, and the Subaru FAST genuine parts catalogue for MY2011 lists the propeller shaft assembly with U‑joints. Note the wheel drive shafts use constant‑velocity (CV) joints, while the U‑joints live in the prop shaft that sends drive to the rear differential.

On the 2011 Exiga, universal joints allow the prop shaft to transmit torque smoothly from the transmission to the rear diff even as the angles change with suspension and engine movement. They’re compact, tough, and crucial for keeping the AWD system quiet and vibration‑free. From factory, these U‑joints are sealed and typically non‑greaseable, and on many OE shafts they’re staked in place. That means routine care is about inspection rather than lubrication.

During regular servicing, it’s smart to check the Exiga’s prop shaft for play and smoothness. With the vehicle safely raised, rotate and wiggle the shaft near each joint, any noticeable free play, notchiness, or rust “weep” marks around the bearing caps points to wear. Also look for sling marks from dried grease, cracked dust seals, and perished centre bearing rubber. A worn U‑joint can show up as a shudder on take‑off, a droning or buzzing vibration around 60–100 km/h, or a faint clunk when selecting drive or reverse.

If a U‑joint is worn, the reliable fix is to replace the propeller shaft assembly, or have a driveline specialist press in serviceable joints and rebalance the shaft. When refitting, mark the flanges so the shaft goes back in the same orientation, use new flange bolts where specified, apply threadlocker if called for, and torque everything to the figures in the Subaru service manual. There’s no set replacement interval, many last well past 150,000–250,000 kilometres depending on use and road conditions. Keeping underbody shields intact and avoiding deep water crossings helps the joints live longer.

• Typical symptoms: take‑off shudder, highway vibration, driveline clunk.
• Service tip: inspect at each service and after any underbody impact.
• Repair path: replace complete prop shaft or rebuild and rebalance with quality joints.

Does the 2011 Subaru Exiga have universal joints or CVs?

It has both. The propeller shaft uses universal joints to carry drive to the rear diff, while the front and rear drive shafts to the wheels use CV joints. If you’re chasing a click on full lock, think CVs, if you’ve got a straight‑line vibration, check the prop shaft U‑joints and centre bearing.

Can the Exiga’s universal joints be greased?

Factory Exiga U‑joints are sealed and usually non‑greaseable. If they’re worn or dry, plan on replacing the prop shaft assembly or having a driveline shop fit serviceable joints and rebalance the shaft. Trying to drill and fit grease nipples to OE staked joints isn’t recommended.

How can an owner check for a worn U‑joint at home?

Safely raise the car, chock the wheels and put it in neutral with the handbrake off. Rotate the prop shaft by hand and feel for rough spots. Then hold the shaft and try to move it up/down and side‑to‑side near each joint, any clunk or visible movement suggests wear. If in doubt, a mechanic can confirm with the Exiga service manual specs.
