Parts for your 2017 Lexus Is-Driveshafts

Understanding Driveshafts on the 2017 Lexus IS

The 2017 Lexus IS is a popular luxury sedan that offers a smooth driving experience and sporty handling. When talking about its drivetrain, "driveshafts" are a key component in many vehicles to transfer power from the engine or transmission to the wheels. But are driveshafts actually part of the 2017 Lexus IS? And if so, what role do they play and how important is it to maintain them? Let's have a closer look.

The 2017 Lexus IS is predominantly rear-wheel drive, although all-wheel drive variants exist as well. In rear-wheel drive vehicles like the Lexus IS, driveshafts are very much relevant. The driveshaft connects the transmission to the rear differential, transmitting engine power to the rear wheels which are responsible for propelling the car forward. In the all-wheel drive versions, additional driveshafts help power the front wheels, making the system more complex but maintaining the core purpose of delivering torque efficiently from the engine to the wheels.

So why are driveshafts needed on vehicles like the 2017 Lexus IS? To break it down simply, the engine and transmission produce power, but the power needs to get to the wheels to actually make the car move. The driveshaft is the vital link in this chain. It is a rugged steel or aluminium tube that spins at very high speeds and transmits torque from the transmission output shaft to the differential. The differential then splits this power to the rear wheels, allowing them to rotate at different speeds when cornering. Without driveshafts, none of this power transmission would be possible and the vehicle would remain stationary, no matter how much engine power was generated.

Driving involves constant changes in torque demand and suspension movement, so the driveshaft must be flexible yet strong. That's why the driveshafts typically include universal joints or constant velocity joints at either end. These joints help accommodate the car's suspension travel and steering angles without causing binding or vibration. Lexus engineers design these parts precisely to balance smooth operation with handling performance.

As a part of the Lexus IS's drivetrain, driveshafts are not generally considered a regular maintenance item in the way that oil or brake pads are. However, they do require occasional inspection and servicing to ensure longevity and prevent costly damage. Over time, the universal or constant velocity joints can wear out or lose lubrication, leading to symptoms such as noticeable clicking noises when turning, vibrations during acceleration, or even clunking sounds when shifting gears.

During servicing or if your Lexus IS exhibits these symptoms, it's a good idea to get the driveshafts checked by a qualified technician. The joints often come packed with grease and sealed to keep contaminants out, but these seals can deteriorate. If moisture or dirt gets inside, it accelerates wear. Regular inspection during service intervals can spot these issues early and prevent driveshaft failure.

If a driveshaft joint is found to be worn or failing, replacement or repair is essential. Driving with a compromised driveshaft can lead to loss of power transfer, vibrations that might affect handling, or even sudden breakdowns. Replacement often involves swapping out entire driveshaft assemblies or sometimes just the affected joints. Lexus genuine parts are recommended to maintain the highest quality and performance standards.

Besides joint wear, the driveshaft tube itself should be visually inspected for dents, bends, or corrosion, especially if the vehicle is driven in harsh conditions or off-road. Any physical deformities can cause imbalance leading to vibrations and premature joint wear. Maintaining the driveshaft balance is important for smooth, comfortable driving.

In everyday driving, owners don't need to think too much about the driveshafts on their Lexus IS, but keeping an ear out for unusual noises or vibrations helps catch early signs of trouble. Regular servicing at a Lexus dealership or a trusted specialist will include a thorough check of the drivetrain components, including the driveshafts.

So, to wrap up, driveshafts play a crucial role in the 2017 Lexus IS's powertrain. Whether it is the rear-wheel drive model that sends power to the back wheels or the all-wheel drive variation that powers all four corners, driveshafts are there spinning away, moving engine power down the line to keep the car moving smoothly. Proper maintenance and timely replacement of worn components ensure this vital part doesn't let you down on the road.
