Parts for your 2020 Subaru Xv-Universal joints

2020 Subaru XV universal joints: what they do and how to look after them

Referencing Subaru’s factory service information (Subaru TechInfo/STIS) for the 2018–2020 XV (GT series) and dealer parts catalogues, universal joints are indeed used on the 2020 Subaru XV. The front and rear drive axles use constant-velocity (CV) joints, while the propeller shaft (driveshaft) that sends torque to the rear differential is a two-piece assembly with a centre support bearing and non-serviceable universal joints (U-joints). Subaru specifies that these U-joints are integral to the prop shaft and are not serviced separately, if worn, the complete shaft assembly is replaced.

On a 2020subaruxv, the universal joints in the propeller shaft are there to let the shaft transmit power smoothly despite changes in angle as the body and suspension move. Unlike the CV joints at the wheels, these U-joints live mid-vehicle, coping with driveline angles and rotation speed rather than steering angles. They’re sealed from the factory, so there are no grease nipples to hit during a routine service, but they still deserve attention during scheduled checks of your 2020subaruxv universaljoints.

What does good care look like? During regular servicing, a tech should inspect for tell-tales like rust-coloured dust around the bearing caps, split seals, sling-off of old grease, and any free play in the cross. On road test, a failing U-joint may show up as a low-speed clunk when taking off or shifting from drive to reverse, or a steady vibration that increases with road speed. Because the XV’s universal joints are non-rebuildable from the factory, the cure for wear is to replace the propeller shaft assembly and renew the centre support bearing hardware as needed.

Owners chasing a smooth, quiet ride should also keep an ear out for droning or thrumming under load, which could point to both U-joint wear and a tired centre support bearing. If the shaft comes out, it’s smart to mark its orientation, follow the factory torque specs, and have the assembly checked for balance if any components have been disturbed. For mixed city–highway use around Australia and New Zealand, a quick visual underbody check each service interval is a safe bet, especially if the vehicle tows or sees corrugated roads.

• Symptoms to watch: take-off clunk, speed-related vibration, chirping or metallic tick, rust “weeping” at the caps.
• Service reality: universal joints on this model aren’t greasable or individually replaceable, replace the prop shaft as a unit.
• Good habits: keep underbody shields intact, address torn seals early, and have driveline angles rechecked after suspension mods.

Does the 2020 Subaru XV use universal joints or just CV joints?

Both are used. The front and rear axles run CV joints for steering and suspension travel, while the propeller shaft uses universal joints to handle driveline angles between the transmission and rear differential. Subaru’s service manuals and parts catalogues list the prop shaft as a two-piece unit with U-joints and a centre support bearing.

How can someone tell if their 2020subaruxv universaljoints need attention?

Typical clues include a clunk when taking off or selecting reverse, a steady-speed vibration, chirping that changes with road speed, or rust staining around the bearing caps. During a service, any free play in the joint or roughness when the shaft is rotated by hand is grounds to replace the propeller shaft assembly.

Can the universaljoints on a 2020 Subaru XV be greased or rebuilt?

No. On this model the universal joints are sealed and not serviceable on their own. If wear is found, the accepted repair is to replace the complete propeller shaft, then road test to confirm the vibration is gone and alignment is spot-on.
