Parts for your 2012 Subaru Exiga-Driveshafts

2012 Subaru Exiga driveshafts — purpose, servicing and replacement advice

Per Subaru’s technical literature for the YA-series Exiga (2012 Driveline/Axle section in the Subaru Workshop Manual and STIS service data), the model uses driveshafts. Every 2012 Exiga has front CV driveshafts (left and right). All-wheel drive variants also run a centre propeller shaft (often called the driveshaft) from the transmission to the rear differential, plus rear CV shafts. Some front-wheel drive trims skip the prop shaft but still rely on front CV driveshafts. So, driveshafts are absolutely relevant on the 2012 Subaru Exiga.

What do they do? Driveshafts transfer engine torque to the wheels while allowing for suspension travel and steering angles. At the front, constant-velocity (CV) joints and boots keep the motion smooth and the grease clean. On AWD Exiga models, the prop shaft sends torque rearward, with universal joints and a centre bearing supporting smooth rotation.

Service-wise, they’re largely fit-and-forget until a boot cracks or a joint wears. The smartest play is regular visual checks at each service: look for split boots, thrown grease, or rusty staining near joints. Catching a torn CV boot early and replacing it can save the cost of a whole shaft. For AWD cars, inspect the prop shaft centre bearing and listen for droning or vibration at highway speeds.

• Common symptoms: clicking on full lock, shudder on take-off, vibration under load, grease flung around the inner guard, or a rhythmic thump with road speed.
• Good practice on replacement: use new axle nuts, confirm ABS tone-ring specs (tooth count/placement), and torque to Subaru figures. For the prop shaft, mark orientation before removal to preserve balance.
• After heavy rain or river crossings common in NZ and Aus, re-check CV boots and re-grease if a clamp’s wept.

Quality parts matter. Reman or new OE-equivalent CV shafts last longer and keep NVH in check. If the centre bearing is noisy, many workshops recommend a complete prop shaft assembly to maintain balance and warranty. Wheel alignment isn’t usually required after a front shaft swap, but if the knuckle’s been disturbed, a quick check won’t hurt. With sensible servicing every 10,000–15,000 km and prompt attention to any boot damage, Exiga driveshafts typically deliver a long, quiet life.

Does the 2012 Subaru Exiga have a driveshaft?
Yes. All trims have front CV driveshafts. AWD models also have a centre propeller shaft to the rear diff, plus rear CV shafts. Some FWD variants omit the prop shaft but still rely on the front CV shafts for drive.

How long do Exiga driveshafts usually last?
In typical Aussie and Kiwi conditions, CV shafts commonly run 150,000–250,000 km if the boots stay intact. Once a boot splits and water or grit gets in, wear accelerates quickly. The AWD prop shaft often lasts the life of the vehicle unless its centre bearing or a universal joint develops play.

Is it better to repair a CV boot or replace the whole driveshaft?
If the joint is still quiet and play-free, a fresh boot and quality grease can be cost-effective. If there’s clicking, vibration, or metal contamination in the grease, replacing the complete shaft is the safer, longer-term fix. For the AWD prop shaft, balance is critical, so many shops prefer assembly replacement if the centre bearing or U-joint is failing.
