Parts for your 2016 Subaru Legacy-Centre bearing

Understanding the Centre Bearing and Its Relevance to the 2016 Subaru Legacy

When it comes to the 2016 Subaru Legacy, a common question that pops up is whether this vehicle features a centre bearing and what role it plays if it does. After referencing a range of technical sources including Subaru service manuals and drivetrain schematics, it's clear that the 2016 Subaru Legacy does not use a centre bearing.

So, what's the deal with centre bearings and why aren't they part of this particular vehicle? Centre bearings are typically found in vehicles with a two-piece driveshaft setup. They serve as a support point that sits between sections of the driveshaft, helping to balance the shaft and reduce vibrations that could lead to damage or excessive wear over time.

In many rear-wheel drive or four-wheel drive vehicles that have a long driveshaft, the driveshaft is split into two parts connected by a centre bearing. This helps to manage the length of the shaft and maintain smooth power delivery from the transmission to the axle. However, the Legacy's drivetrain design doesn't call for this sort of arrangement.

The 2016 Subaru Legacy is equipped with Subaru's renowned symmetrical all-wheel drive system combined with a horizontally opposed 'boxer' engine and a relatively short driveshaft. The design is compact and efficient, eliminating the need for a two-piece driveshaft and, by extension, a centre bearing.

The driveshaft on the 2016 Legacy is a single-piece design that connects the transmission to the rear differential (where applicable, depending on trim and drivetrain configuration). Because the driveshaft length is manageable within this setup, and the design maintains a good balance and alignment, a centre bearing isn't necessary to support it. This helps keep the drivetrain simple, rugged, and easier to maintain over time.

So with no centre bearing fitted, what should Subaru Legacy owners keep an eye on regarding the drivetrain? Well, while the centre bearing isn't relevant, the CV joints that connect the driveshaft to the wheels and differential are crucial in maintaining smooth power transfer and preventing vibrations. These joints should be checked regularly for boot damage, grease leakage, or wear.

Also, the constant velocity joints and the universal joints elsewhere in the drivetrain demand routine inspection and occasional servicing to ensure the Legacy maintains its smooth, reliable driving experience. The driveshaft itself is designed to be maintenance-free, but any noticeable vibrations, clunks, or unusual noises under acceleration or turning could indicate a problem with the drivetrain components.

You might wonder what happens if a centre bearing is neglected in vehicles that do have them. Generally, a worn or damaged centre bearing can cause driveline vibrations, noise, excessive wear on other drivetrain components, and in severe cases, complete failure of the driveshaft. But since the 2016 Subaru Legacy doesn't have this part, this particular concern doesn't apply.

Given the Legacy's design, if you're servicing the vehicle or troubleshooting drivetrain issues, focus on the CV joints, boots, and related axle components. Regular inspection, especially in dusty or wet environments typical in many parts of Australia, is key to prolonging the life of these parts. Wear and tear can happen much quicker if these protective boots crack or split and road debris or water gets in.

In short, while the term centre bearing is an important one for many car owners and mechanics, the 2016 Subaru Legacy's drivetrain setup makes this part unnecessary. Subaru's clever mechanical design reduces the number of components required without compromising performance or durability.

For those interested in servicing, routine checks on the driveshaft area are still important but it comes down to ensuring the CV joints and boots are intact and grease levels are sufficient. If your Legacy ever starts showing driveline vibrations or noises, a thorough check of the CV joints and related parts is the way to go rather than looking for a non-existent centre bearing.

That said, keeping up with your Subaru's service schedule and having a trusted mechanic perform these inspections will help keep the car running smoothly on Australian roads for years to come.
