Parts for your 2017 Toyota Avensis-Driveshafts

Understanding Driveshafts in the 2017 Toyota Avensis

The 2017 Toyota Avensis is a popular mid-size family car in Australia, known for its reliability and smooth driving experience. When it comes to this vehicle's drivetrain components, one might wonder if driveshafts are involved and what role they play. To clarify, driveshafts are indeed an important part of many vehicles but whether they are used in the 2017 Avensis depends on the drivetrain layout.

The 2017 Toyota Avensis typically comes with a front-wheel-drive (FWD) system, which means the engine's power is delivered to the front wheels. Unlike rear-wheel-drive or all-wheel-drive vehicles, which often use a long driveshaft to transfer power from the gearbox or transfer case to the rear axle, front-wheel-drive cars like the Avensis don't require this type of driveshaft. Instead, they use shorter half shafts, sometimes called drive shafts or axle shafts, which connect the transaxle to each front wheel.

So, while the traditional driveshaft that runs longitudinally under the car from front to rear doesn't exist in the 2017 Toyota Avensis, the front axle shafts perform a similar function in transferring power from the transmission to the wheels. These half shafts are crucial components that allow the front wheels to spin and propel the car forward.

For those wondering why there is no classic driveshaft in this car, it's simply down to the layout. The FWD setup is compact, efficient, and reliable, removing the need for a lengthy driveshaft. It also contributes to better fuel economy and more cabin space since the bulky driveshaft tunnel is not required. This makes the 2017 Avensis ideal for everyday use and city driving where manoeuvrability and comfort are priorities.

Driving a car without a traditional driveshaft doesn't mean you don't have to think about drive components at all though. The half shafts or drive shafts fitted to the front wheels require attention for vehicle upkeep and safety. Here's a bit more about the purpose of these shafts and how they fit into regular maintenance for the 2017 Toyota Avensis.

The half shafts on the Avensis act as critical links between the transaxle and front wheels. As the engine generates torque, the transaxle converts this power and sends it through these shafts to the wheels, causing them to turn. Because they need to handle twisting forces and allow the wheels to move up and down with the suspension, these shafts have flexible joints known as constant velocity (CV) joints at their ends.

CV joints are vital as they accommodate the complex movements of the suspension and steering system, all while maintaining smooth power delivery. Over time, these CV joints and the driveshafts themselves can wear out due to normal use, exposure to the elements and road debris. The most common sign of wear is a clicking noise when turning or vibrations felt during acceleration.

Maintaining the driveshafts and CV joints on the Avensis involves routine checks during servicing. Mechanics will typically inspect CV joint boots for cracks or tears that can let grease escape and contaminants in. If these boots are compromised, the joints may fail prematurely, leading to costly replacements. Regularly greasing and ensuring the boots are intact can extend the life of your shafts significantly.

When it comes to replacements, if a driveshaft or CV joint is damaged or worn out, it's best to replace it promptly. Driving with a faulty driveshaft can cause further damage to the transmission or suspension components, and may result in loss of vehicle control in severe cases. Replacement parts for the 2017 Toyota Avensis are widely available and affordable, often sourced from both Toyota dealers or quality aftermarket suppliers.

It's also worth noting that while replacing half shafts or CV joints, mechanics typically recommend doing both sides at the same time if one is worn out. This helps maintain balanced performance and extends the overall service life.

On a day-to-day level, owners of the 2017 Avensis can help prolong driveshaft life by avoiding harsh acceleration, regularly washing the underbody to remove corrosive substances like road salt and addressing any strange noises or vibrations early on. Being proactive with these simple steps can save money and improve vehicle safety.

So, in short, while the 2017 Toyota Avensis does not have a traditional, full-length driveshaft like rear or all-wheel-drive vehicles, it absolutely relies on front axle shafts complete with CV joints to deliver power to the front wheels. Looking after these drive components through proper maintenance and timely repairs will keep the Avensis running smoothly and safely for many years to come.
