Parts for your 2013 Subaru Outback-Driveshafts

2013 Subaru Outback driveshafts — purpose, care, and when to replace

Yes, driveshafts are absolutely used on the 2013 Subaru Outback. Technical references including the Subaru Factory Service Manual for 2010–2014 Outback/Legacy, the Subaru Technical Information System (STIS), and OEM parts catalogues list three key driveline components on this model: left and right front driveshafts (CV axle shafts), left and right rear driveshafts (half-shafts), and a centre propeller shaft linking the transmission to the rear differential. Being an all-wheel drive Subaru, it relies on these shafts to deliver torque to all four wheels.

On this Outback, the driveshafts do the hard yards transferring engine power smoothly through constant-velocity (CV) joints that can articulate with steering and suspension movement. The centre prop shaft handles fore–aft power delivery and includes a centre support bearing, its U-joints are non-serviceable on this generation, so the complete assembly is replaced if worn.

Good servicing keeps the driveline quiet, smooth, and dependable:

• Inspect CV boots at each service (around every 10,000–15,000 km). Split boots fling grease and quickly destroy CV joints.
• Listen and feel: a rhythmic clicking on turns points to a front CV joint, a shudder on take-off or a droning vibration at highway speeds can suggest a worn prop shaft bearing or U-joint.
• Check for sling marks of grease around the inside of the wheels or underbody — a tell-tale of a failing boot.
• If a boot has only just split, some joints can be cleaned and rebooted, if the joint’s noisy or gritty, replace the shaft.

Replacement tips specific to the 2013 Outback:

• Use quality shafts that match OEM specs, cheap units can vibrate or have short boot life.
• Always fit a new axle nut and torque it to the specified value from the Subaru service data. Recheck torque after initial kilometres if recommended.
• For the centre prop shaft, replace the complete unit if the staked U-joints or centre bearing are worn, they’re not designed to be serviced individually on this model (per Subaru service information).
• After front shaft work, an alignment check is a smart idea if any suspension bolts were loosened.

Look after the driveshafts and the Outback’s trademark sure-footed AWD feel will stay crisp, quiet, and ready for long Kiwi or Aussie road trips.

FAQs

What are common signs my 2013 Outback driveshafts need attention?
Clicking on full lock, grease flung near a wheel, vibrations under acceleration, or a humming that follows road speed are the big giveaways. If the centre prop shaft bearing goes, expect a droning or a thump on take-off.

How often should the CV boots be checked?
At every routine service — roughly 10,000–15,000 km in Aussie/NZ conditions. More often if the vehicle sees gravel roads, coastal salt, or heavy towing.

Are the propeller shaft U-joints serviceable on this model?
No. Per Subaru’s service documentation for the 2010–2014 Outback, the prop shaft uses staked U-joints and a non-serviceable centre bearing. If worn, the complete assembly is replaced.
