2022 Subaru XV universal joints: what they do and when to replace them

Based on the Subaru Workshop Manual for the XV (GT series, 2018–2022) and Subaru parts catalogues for these models, the 2022 Subaru XV uses a two-piece propeller shaft (driveshaft) with cardan-type universal joints (U‑joints) and a centre support bearing. The front and rear drive shafts to the wheels use constant velocity (CV) joints, but the propeller shaft between the transmission and rear differential relies on U‑joints that are sealed and non-greasable. Many listings note the assembly as “non-serviceable,” meaning Subaru supplies the shaft as a complete unit if the joints wear.

On the XV, the universal joints let the prop shaft transmit torque at slight angles as the engine and rear diff move under load. They’re the quiet achievers — keeping the all-wheel drive smooth while the suspension does its thing. Because the factory joints are sealed, there’s no greasing on routine services. Instead, smart servicing is all about inspection and catching wear early.

What to look and listen for:

• A dull clunk when shifting from reverse to drive, or when getting on/off the throttle
• Vibration or a buzz through the floor between about 40–80 km/h
• Chirping or squeaking that changes with road speed
• Red/brown dust around bearing caps, or any play at the joints when the shaft is unloaded

Recommended service habits for the 2022 XV’s U‑joints:

1. Inspection every 20,000–30,000 km during routine servicing, or sooner after off‑road water crossings or beach runs.
2. If any play, binding, or gritty movement is felt with the shaft disconnected, plan replacement. On this model the OE joints are staked in, Subaru specifies replacing the complete propeller shaft.
3. Specialist driveline shops can rebuild the shaft with serviceable U‑joints and rebalance it — a solid option if the centre bearing is tired too.
4. When fitting a new or rebuilt shaft, align the phasing marks, use new flange bolts/nuts, and torque to spec to avoid vibrations.
5. After installation, road-test for shudder under load and coast-down. If needed, recheck flange seating and balance.

With normal on-road use, XV U‑joints often last well past 150,000 km. Heavy towing, corrugations, and mud or saltwater can shorten that. Because the joints are sealed, prevention means regular underbody rinsing, periodic checks on the centre bearing rubber, and jumping on any driveline noises early. Technical documentation for MY18–22 XV/Crosstrek confirms the propeller shaft’s universal-joint design and “maintenance-free” construction, so a watchful eye and timely replacement is the right play.

Popular questions

Does the 2022 Subaru XV actually have universal joints?

Yes. Technical documentation for the 2018–2022 XV shows a two-piece propeller shaft with cardan U‑joints and a centre support bearing. The wheel shafts use CV joints, but the prop shaft to the rear diff is where the U‑joints live.

They’re sealed from factory and sold by Subaru as part of the complete propeller shaft assembly.

How long do the XV’s universal joints last, and what are the signs they’re worn?

Many last 150,000–250,000 km with gentle use. Harsh roads, water, and salt can bring that forward.

Clunks on take-off, speed-related vibration, and squeaks are the usual tell-tales. Any visible play at the caps or rust-coloured dust means it’s time to act.

Can they be greased or serviced, or is replacement the only fix?

The OE U‑joints are sealed and not greasable. Subaru supplies the whole prop shaft if the joints fail.

A driveline specialist can rebuild the shaft with replaceable U‑joints and then rebalance it, which is a practical alternative to a new assembly.
