CV Joint on the 2017 Toyota Crown: Purpose, Maintenance, and Replacement Advice

The 2017 Toyota Crown is a sophisticated luxury sedan that blends comfort, performance, and advanced technology. When considering the drivetrain components like Constant Velocity (CV) joints, it is important to determine whether this part is relevant to the vehicle. Based on technical references and drivetrain configurations, the 2017 Toyota Crown, especially in its rear-wheel-drive and hybrid variants, does not use traditional front axle CV joints. Instead, it employs more conventional rear-wheel drive or hybrid power transfer systems that rely on other drivetrain components such as universal joints or driveshafts.

To break this down, CV joints are primarily used in front-wheel-drive and all-wheel-drive vehicles to allow the front axle shafts to transmit power smoothly to the wheels while accommodating steering angles and suspension movement. Since the 2017 Toyota Crown is fundamentally a rear-wheel-drive platform with a longitudinal engine layout, the front wheels are not driven and do not need CV joints. Instead, the power is sent to the rear wheels using a driveshaft with universal joints, which handle the angular movement and rotation differently from a CV joint.

So, why is no CV joint needed on the 2017 Toyota Crown? This comes down to the vehicle's drivetrain design. CV joints are engineered to maintain a constant rotational speed between the transmission and the wheels, even as the wheels turn left or right and as the suspension moves. They are essential in front-wheel-drive vehicles where the front wheels both steer and drive the car. The Toyota Crown's rear-wheel-drive setup means the driven wheels don't steer, making traditional CV joints unnecessary. Rear-wheel-drive vehicles typically use simpler universal joints located in the driveshaft, as these joints do not have to accommodate steering movement.

For hybrid versions of the Crown, the electric motors often drive the rear wheels or use a different transmission layout that also avoids the need for CV joints on the front axle. Instead, specialised joint types and motor coupling systems handle the power delivery.

Given that CV joints are not used on the 2017 Toyota Crown, the focus of maintenance should be on other drivetrain components that do wear out, such as universal joints, driveshafts, and differential gears. However, it is still useful to understand the role of CV joints in vehicles where they are fitted, especially to appreciate what this part does and best practices if your vehicle did have them.

Constant Velocity joints are crucial in front-wheel-drive and all-wheel-drive cars because they transmit power from the transmission to the wheels at a constant speed without increases or decreases, even while the wheels are turning and the suspension is moving. This prevents vibrations or interruptions in power delivery, which makes for smoother driving and more reliable traction. The unique design of a CV joint allows it to flex in multiple directions, dealing with the need to turn the wheels for steering and move up and down with suspension travel.

CV joints are typically covered by rubber boots that keep grease in and dirt and moisture out. It's these boots that are often the first signs of trouble, as cracks or tears can allow contaminants to enter, which leads to joint wear and eventual failure. When a CV joint starts to fail, common symptoms include clicking or popping noises during sharp turns, vibrations during acceleration, or grease splattered inside the wheel arch caused by a torn boot.

Maintaining CV joints is pretty straightforward but very important for longevity and driving comfort. Regular servicing checks during vehicle maintenance should include inspecting the condition of the CV boots for any damage, grease leaks, or signs of wear. If a boot is damaged, it is best to replace it immediately to prevent dirt ingress and joint failure. Sometimes the whole CV joint assembly needs replacement, especially when the joint has started making noise or can no longer transmit power smoothly.

When it comes to replacing a CV joint on vehicles that use them, the process generally involves removing the damaged joint from the axle shaft and fitting either a new joint or a new axle shaft assembly, depending on the extent of damage. It is not recommended to ignore worn or damaged CV joints as continued use can lead to complete joint failure, leaving the vehicle undriveable and potentially unsafe.

Routine vehicle servicing in Australia, particularly for those in urban or rougher rural driving conditions, should pay attention to these components, especially if the vehicle originates from a front or all-wheel drive platform. Keeping CV joints in good condition improves driving smoothness, extends the life of the drivetrain, and enhances safety by preventing sudden drivetrain faults.

Ultimately, while the 2017 Toyota Crown does not use CV joints due to its rear-wheel-drive design, understanding the importance of this component helps highlight why some vehicles require specific care for their drive systems. For Toyota Crown owners, focusing on the driveshaft, universal joint, and differential service schedules is crucial. If ever faced with a Toyota model that does use CV joints, regular inspection and prompt maintenance make all the difference in keeping the car running quietly and efficiently for many thousands of kilometres.
