Parts for your 2021 Lexus Is-Cv joint

Understanding the CV Joint on the 2021 Lexus IS

The 2021 Lexus IS is a sporty luxury sedan that offers a smooth and reliable driving experience. When it comes to driveline components, one key part that may come up in discussions is the CV joint, or constant velocity joint. So, does the 2021 Lexus IS use CV joints? The answer is yes, but it depends on the specific drivetrain layout of the vehicle.

The 2021 Lexus IS comes with rear-wheel drive as standard, with an all-wheel-drive (AWD) variant also available. On the rear-wheel-drive models, the power from the engine is transmitted to the rear wheels via a driveshaft and differential system that utilises universal joints (U-joints) rather than CV joints. However, on the AWD versions, the front wheels are driven through half shafts that do use CV joints. This is because the front wheels require constant velocity joints to allow for smooth power delivery while the wheels are turning and oscillating with suspension movement.

So, if you own a rear-wheel-drive 2021 Lexus IS, CV joints are not part of your rear driveline. But if you have the all-wheel-drive model, CV joints are definitely fitted on the front axles. This makes understanding CV joints important, especially if you want to keep your AWD Lexus IS running smoothly and avoid unexpected repair costs.

Let's look at what a CV joint does and why it is crucial for your AWD Lexus IS, along with some tips on maintaining and replacing these components when needed.

The CV joint's main purpose is to transmit power from the car's transmission to the wheels while allowing for up-and-down suspension movement and steering changes. Unlike simpler universal joints, CV joints maintain a constant rotational speed regardless of the angle, which results in smoother power delivery with minimal vibration. This is particularly important on the front wheels of the AWD Lexus IS, which not only drive the car forward but also steer it left and right and move with the suspension.

CV joints are typically located inside rubber or plastic boots called CV boots. These boots protect the joints from dirt, debris, and moisture while trapping the grease that lubricates the moving parts. Over time, these boots can crack or split due to exposure to the elements, road debris, or just general wear and tear. When that happens, the grease escapes and contaminants get in, causing the CV joint to wear prematurely and eventually fail.

For Lexus IS owners with AWD, regular inspection of CV boots during servicing is essential. Mechanics will check for any tears, grease leaks around the boot edges, or unusual noises while driving - such as clicking or popping sounds when turning hard. These noises are a classic sign of a worn or damaged CV joint.

If a CV joint needs replacement, it's a task that should be tackled sooner rather than later. Continuing to drive with a failing CV joint can lead to complete joint failure, which could leave the vehicle immobilised or cause further damage to the driveshaft or suspension. Generally, replacement involves removing the old joint and boot, installing a new joint complete with a fresh boot and grease, then securing everything properly. Most modern replacement parts come as a kit that makes the job clean and reliable.

Maintaining your CV joints helps extend the overall lifespan of your car's drivetrain and ensures smoother, quieter operation. Here are some key tips for keeping those CV joints healthy on your 2021 Lexus IS AWD model:

• Have the CV boots inspected at each service interval or if you notice grease splattered around the wheel arches.
• Listen for clicking or popping noises when making tight turns, which can signal joint wear.
• Avoid aggressive driving over rough terrain, which can increase stress on the joints and boots.
• If a boot is damaged, have it replaced immediately to protect the joint.
• Use genuine or reputable aftermarket replacement parts to ensure quality and fitment.

For rear-wheel-drive Lexus IS models, the driveline does not incorporate CV joints on the rear axles. Instead, it relies on a traditional driveshaft with universal joints that handle the necessary shaft articulation. These universal joints are different components with their own maintenance and replacement routines but typically last a long time under normal driving conditions.

In short, the presence of CV joints on the 2021 Lexus IS really comes down to whether the vehicle is AWD or pure rear-wheel drive. AWD variants have CV joints on the front axles to handle power delivery and steering rotations smoothly. Maintaining these joints is an important part of ownership and can help avoid costly repairs down the track. For RWD models, CV joints are not part of the drivetrain, so owners need not worry about them, focusing instead on universal joint condition and other driveline components.

Keeping an eye on the CV joint boots, listening for warning noises, and addressing any issues promptly will help AWD Lexus IS owners enjoy the confident handling and refined ride their car is designed for. After all, proper care keeps your car moving smoothly and makes sure it can handle everything Aussie roads throw at it.
