Parts for your 2007 Subaru Outback-Driveshafts

2007 Subaru Outback driveshafts: what they do and how to look after them

Yes, driveshafts are absolutely relevant and fitted to the 2007 Subaru Outback. Technical references including the Subaru Factory Service Manual for Legacy/Outback BP/BL (Driveline/Axle and Propeller Shaft sections), the Subaru Electronic Parts Catalogue for BP Outback, and general guides like the Haynes Repair Manual (Legacy & Outback 2000–2009) all show two key driveshaft types on this model: front CV axle shafts to each hub, and a two‑piece propeller shaft running from the transmission to the rear differential. That’s true across 2.5 and 3.0 petrol variants, manual and auto, as they’re all full‑time AWD.

The job of these shafts is to send torque from the gearbox to the wheels, smoothly and reliably, while the suspension moves and the front wheels steer. Up front, constant‑velocity (CV) joints let the Outback turn lock‑to‑lock without shudder. Underneath, the propeller shaft uses a centre support bearing and joints that handle angle changes as the car loads up over bumps and corrugations. When they’re healthy, everything feels quiet and vibration‑free.

As part of regular servicing, they’re worth a look. A quick visual check during oil changes can save a lot of grief later:

• Inspect CV boots for splits, perishing or grease fling around the inner guards.
• Listen for clicking on tight turns (front CV joints) and feel for shudder or vibration on take‑off or at highway speeds (prop shaft joints or centre bearing).
• Check for oil seepage at transmission and diff output seals that can contaminate joints.

If replacement’s on the cards, stick with quality shafts and new hardware as specified in the factory manual. Rebooting and regreasing a sound CV joint is often viable if caught early, if the boot’s been torn for a while and the joint’s gritty, a complete axle is the better bet. For the propeller shaft, inspect the centre support bearing and rubber mount, if they’re cracked or sloppy, replace them when the shaft is out. Mark the shaft orientation before removal to help preserve balance, and always support the vehicle on stands—never just a jack.

After any driveshaft work, recheck torques after a short drive, keep an eye out for new leaks, and make sure any retaining pins, clips or flange bolts match the Subaru spec noted in the workshop manual or STIS. Done right, the Outback’s driveline will stay quiet, tight and ready for the long haul across Aussie or Kiwi back roads.

• Popular questions about 2007 Subaru Outback driveshafts

Do all 2007 Outbacks have a rear driveshaft?
They do. The 2007 Outback is full‑time AWD, so every model uses a two‑piece propeller shaft to drive the rear differential. This layout is shown in the Subaru Factory Service Manual and the Subaru parts catalogue for BP/BL models.

What are the common signs a driveshaft is failing?
Front CV issues usually show up as clicking or knocking on tight, low‑speed turns, plus grease flung from a split boot. Propeller shaft wear more often feels like a vibration under acceleration or a droning hum at certain speeds, sometimes accompanied by a perished centre support bearing.

Can a torn CV boot be repaired, or does the whole axle need replacing?
If the tear is recent and the joint hasn’t run dry or gritty, a new boot and fresh CV grease can be a cost‑effective fix. If there’s noticeable play, rust‑coloured grease, or persistent noise, a complete axle assembly is the smarter long‑term solution.
