The Lexus IS has long been celebrated for its blend of luxury and performance. However, for enthusiasts looking to elevate their driving experience, particularly during cornering, installing a limited slip differential (LSD) can make a significant difference. This article will guide you through the benefits of an LSD and provide a step-by-step installation process.
Understanding Limited Slip Differentials
A limited slip differential is a type of differential that helps to distribute torque to the wheels with the most grip. This is particularly beneficial during cornering, where one wheel may lose traction. By allowing for better power distribution, an LSD enhances stability and performance.
Benefits of Installing a Limited Slip Differential
- Improved Cornering Performance: An LSD allows for better traction when navigating turns, reducing understeer and oversteer.
- Enhanced Stability: With power being sent to the wheel with the most grip, the vehicle remains stable during aggressive driving.
- Increased Acceleration: A limited slip differential can improve acceleration out of corners, providing a quicker exit speed.
- Better Handling: The overall handling of the vehicle is improved, allowing for a more confident driving experience.
Preparing for Installation
Before starting the installation of a limited slip differential in your Lexus IS, it’s crucial to gather the necessary tools and materials. Here’s what you’ll need:
- Limited Slip Differential Kit
- Floor Jack and Jack Stands
- Socket Set
- Torque Wrench
- Gear Oil
- Safety Glasses and Gloves
Step-by-Step Installation Process
1. Prepare the Vehicle
Start by parking the vehicle on a flat surface and engaging the parking brake. Use a floor jack to lift the rear of the car and secure it with jack stands.
2. Remove the Rear Differential Cover
Using a socket set, remove the bolts securing the rear differential cover. Carefully pry the cover off and drain the old gear oil into a suitable container.
3. Remove the Old Differential
Once the cover is removed, take out the old differential assembly. This may require removing additional components like the axles or driveshaft, depending on your vehicle’s configuration.
4. Install the Limited Slip Differential
Carefully position the new limited slip differential into the differential housing. Ensure that it is seated properly and that all components align correctly.
5. Reassemble the Differential
Reinstall any components that were removed, including the axles and driveshaft. Once everything is in place, attach the differential cover using new gasket material or sealant to prevent leaks.
6. Fill with Gear Oil
Fill the differential with the appropriate gear oil as specified in your vehicle’s manual. Ensure that you do not overfill, as this can cause foaming and other issues.
7. Test Drive
Lower the vehicle from the jack stands and take it for a test drive. Pay attention to how the car handles during cornering and ensure that there are no unusual noises or issues.
Conclusion
Installing a limited slip differential in your Lexus IS can significantly enhance your vehicle’s performance, especially during cornering. With improved traction, stability, and handling, you’ll experience a more enjoyable and confident driving experience. Always ensure that you follow safety precautions and consult a professional if you are unsure about any part of the installation process.
