Parts for your 2017 Lexus Is-Universal joints

Understanding Universal Joints on the 2017 Lexus IS

The 2017 Lexus IS is a sleek and well-engineered vehicle, designed with performance and comfort in mind. If you've been looking into its drivetrain components, you might have come across the term "universal joints" or U-joints. But are universal joints used in the 2017 Lexus IS? Getting to the bottom of this requires a quick look at the type of drivetrain this model has and what components typically serve in these systems.

The 2017 Lexus IS comes with rear-wheel drive or all-wheel drive configurations, depending on the specific model. In many vehicles with a rear-wheel or all-wheel drive layout that uses a driveshaft to transfer power from the engine to the rear differential, universal joints are typically part of the setup. Their job is to allow the driveshaft to flex and transmit torque smoothly even as suspension movement causes changes in angle between the transmission and the rear axle.

However, the 2017 Lexus IS uses a more modern approach. Instead of traditional universal joints in the driveshaft, the vehicle uses constant velocity (CV) joints where necessary, especially in the front axles of all-wheel drive models. CV joints serve a similar purpose but offer smoother power transfer at varying angles, and they are generally more durable and quieter than classic U-joints. Also, the driveshaft in the Lexus IS is designed as a solid, balanced piece with precision mounts designed to reduce the need for traditional universal joints.

So if you own a 2017 Lexus IS and are wondering about universal joints, the simple answer is that they either are not present in the traditional sense or have been replaced by other joint technologies that perform better with the modern drivetrain design. In this way, Lexus uses advanced engineering solutions to optimise performance, stability, and reliability.

Why doesn't the 2017 Lexus IS use traditional universal joints? There are a few key reasons. Universal joints can sometimes cause vibration or noise if they wear out or are not maintained properly. They also require regular greasing to keep working smoothly. By using CV joints and a precisely engineered driveshaft system, Lexus eliminates the common maintenance hassles associated with universal joints and improves overall driving refinement. The seamless power delivery and reduced drivetrain NVH (noise, vibration, harshness) really suit a luxury sports sedan atmosphere.

But for enthusiasts and DIY car lovers who want to learn a bit about universal joints in general, here is some useful info. Universal joints are flexible couplings that transmit rotational torque between shafts that aren't in a straight line. These joints can bend and flex to accommodate suspension movement, steering angles, or other changes in shaft alignment. You'll most commonly find them on rear-wheel drive vehicles with traditional propeller shafts and on front axles of some older front-wheel drive cars.

Due to their function, universal joints are a critical part of drivetrain integrity. When functioning correctly, they prevent drivetrain vibration, maintain smooth power transfer, and allow for necessary movement between drivetrain components.

Maintenance of universal joints is quite straightforward but important if the vehicle uses them. They should be checked regularly for signs of wear, such as:

• Clunking noises when shifting gears or starting off
• Vibration at certain speeds
• Visible rust or corrosion on the joint or yoke
• Loose or excessive play in the joint when manipulated by hand

Replacing a universal joint isn't overly complicated but does require some specialised tools or a trip to a mechanic. The worn joint will cause drivetrain imbalance and could ultimately lead to driveshaft failure if neglected. Replacing U-joints as soon as symptoms appear ensures safety and avoids more costly repairs down the track.

Even though the 2017 Lexus IS does not generally use traditional universal joints, understanding their role helps appreciate modern engineering choices. Lexus has opted for CV joints and sophisticated driveshaft designs that require less regular attention and offer improved performance - perfect for the smooth, quiet ride that Lexus drivers expect.

When maintaining your Lexus, it is always a good idea to keep an ear out for any unusual noises or vibrations from the drivetrain and have these inspected. While universal joints might not be a concern, other components like the CV joints, driveshaft, and differential will still need their share of care to keep your 2017 IS running at its best.
