Parts for your 2014 Subaru Outback-Driveshafts

Understanding Driveshafts on the 2014 Subaru Outback

The 2014 Subaru Outback is a popular choice for Aussies who want a reliable, versatile wagon that can handle a bit of dirt, gravel, and everything in between. It rolls out with Subaru's signature all-wheel drive system which is key to its strong off-road and all-weather performance. When it comes to the topic of driveshafts on this vehicle, it's important to clarify whether this part is used and what role it plays in the Outback's driveline.

Technically speaking, a driveshaft is a mechanical component used to transfer power from the engine, through the transmission or transfer case, to the wheels. In many rear-wheel drive and part-time four-wheel drive vehicles, driveshafts are essential as they carry rotational force to the rear wheels, especially in vehicles with separate front and rear axles. However, the 2014 Subaru Outback is a bit different.

The 2014 Outback uses a full-time all-wheel drive system powered by Subaru's symmetrical AWD setup. This means power is distributed to all four wheels all the time via a central differential paired with viscous coupling systems. The Outback's powertrain layout is primarily a boxer engine up front, connected directly to a transmission that sends power forward to the front wheels and backward to the rear wheels through relatively short shafts known as half-shafts or drive axles.

Simply put, the 2014 Subaru Outback does not have a traditional long driveshaft running the length of the vehicle like some larger trucks or SUVs with body-on-frame construction. Instead, it uses these half-shafts which are essentially short driveshafts that connect the differential to each wheel. Because it's a unibody vehicle with a flat boxer engine mounted longitudinally at the front, the power delivery system is inherently compact and integrated differently.

So what does this mean for someone curious about driveshafts in the 2014 Outback? While it does not have a conventional driveshaft, it certainly relies on its half-shafts to transmit power from the AWD system to the wheels. These are critical for the drivability and safety of the vehicle especially on slippery roads or rugged terrain.

If you are a Subaru Outback owner or considering buying one, it's good to know a bit about these half-shafts since they perform essentially the same function as a conventional driveshaft but are different in size and application. Proper maintenance and inspection of these components plays a role in the overall health of the vehicle's AWD system.

Half-shafts on the 2014 Outback connect the front and rear differentials to the wheels via constant velocity (CV) joints. These CV joints allow the shafts to flex and pivot with suspension movement and steering angles whilst transferring torque smoothly. Over time, the rubber boots covering these joints can crack or tear, letting dirt and water in, which accelerates wear on the joint itself.

During routine servicing, technicians check these CV boots and shafts for any signs of damage or leaks. If a torn boot is spotted early, it might be possible to replace the boot only, however, once the joint has been contaminated or worn out, the entire half-shaft usually needs replacement. Replacing a damaged half-shaft on an AWD vehicle like the Outback is crucial because ignoring problems can lead to vibration, noise, or even loss of power delivery to one or more wheels.

Replacing a half-shaft might seem like a fair bit of work but Subaru designed the Outback with serviceability in mind. In most cases, half-shaft replacement is straightforward for a skilled mechanic and uses OEM or high-quality aftermarket parts to ensure reliability and performance.

Some key tips for maintaining driveshaft-related components on the 2014 Subaru Outback include regular visual inspections during oil changes or tyre rotations, paying attention to any clicking or clunking sounds when turning or accelerating, and addressing any grease leaks promptly. Following the recommended service intervals and using Subaru-approved parts will help keep your Outback's AWD system running smoothly for many kilometres.

In essence, while the 2014 Subaru Outback does not have a traditional single driveshaft running from front to rear, it utilises half-shafts with CV joints to distribute power effectively to all four wheels. Treating these components with care and conducting proper maintenance is important to maintain the vehicle's signature traction and balance, no matter where the journey takes you.
