Replacing the struts on a Lexus IS is a crucial maintenance task that can improve ride quality and handling. Properly replacing the struts ensures your vehicle remains safe and comfortable on the road. This guide provides a step-by-step overview of the process, suitable for DIY enthusiasts and professional mechanics alike.
Tools and Materials Needed
- Socket set and ratchet
- Spring compressor
- Jack and jack stands
- Wrench set
- Replacement struts for Lexus IS
- Torque wrench
- Penetrating oil
- Safety gloves and glasses
Preparation Steps
Begin by parking your Lexus IS on a flat surface. Engage the parking brake and wear safety gear. Loosen the lug nuts on the wheel where you’ll replace the strut, but do not remove them yet. Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel to access the suspension components.
Removing the Old Strut
Locate the strut assembly in the wheel well. Spray penetrating oil on bolts and nuts to ease removal. First, disconnect the brake line or ABS sensor if necessary, then remove the bolts securing the strut to the steering knuckle. Support the strut with a jack or assistant to prevent it from falling.
Next, open the hood and locate the strut mount bolts at the top of the strut tower. Remove these bolts carefully. With the strut free, carefully lower it out of the wheel well. Be cautious of any remaining connections or components.
Installing the New Strut
Position the new strut into the wheel well, aligning it with the mounting points. Secure the top mount bolts first, tightening them to the manufacturer’s specified torque. Reattach the lower bolts to the steering knuckle, ensuring they are tight and secure. Reconnect any disconnected lines or sensors.
Before reinstalling the wheel, double-check all bolts and connections. Lower the vehicle carefully and tighten the lug nuts to the specified torque. Replace the wheel and lower the vehicle completely onto the ground.
Final Checks and Test Drive
Once the vehicle is back on the ground, double-check all fasteners. It’s recommended to perform a wheel alignment after strut replacement to ensure optimal handling. Take the Lexus IS for a test drive to assess the ride quality and listen for any unusual noises.
Replacing struts on a Lexus IS can be straightforward with the right tools and precautions. Regular maintenance helps keep your vehicle performing at its best and extends its lifespan.
