Lexus RX 2020-present Drivetrain Specifications

The 2020-Present Lexus RX offers two drivetrain options: Front-Wheel Drive (FWD) and All-Wheel Drive (AWD). The AWD system, known as Lexus Dynamic Torque Control AWD, automatically distributes torque between the front and rear wheels for optimal traction and stability. Both drivetrains are paired with a 3.5L V6 engine or a hybrid powertrain, depending on the model variant.

Regular maintenance for the Lexus RX drivetrain includes checking and replacing the transmission fluid every 60,000 miles, inspecting the driveshaft and differential for wear, and ensuring the AWD system's electronic components are functioning properly. Additionally, tire rotation every 5,000 miles is recommended to maintain even wear and drivetrain efficiency.

Replacing drivetrain components, such as the driveshaft or differential, requires lifting the vehicle and removing the undercarriage panels. Disconnect the driveshaft from the transmission and differential, then unbolt and replace the faulty component. For AWD models, ensure the torque distribution system is recalibrated after replacement. Always refer to the service manual for detailed instructions and torque specifications.

Unusual noises from the drivetrain, such as clunking or whining, may indicate issues with the driveshaft, differential, or transmission. First, check for loose or worn components. If the noise persists, inspect the transmission fluid level and quality. For AWD models, ensure the torque distribution system is functioning correctly. If the issue remains unresolved, consult a certified technician for further diagnosis.

To optimize drivetrain performance, use high-quality transmission fluid and ensure regular maintenance. For AWD models, keep tires properly inflated and rotated to maintain balanced traction. Avoid aggressive driving, which can strain the drivetrain. Additionally, consider upgrading to performance-grade components, such as a limited-slip differential, for enhanced handling and power distribution.
