### Tools and Equipment Needed
– **Jack and Jack Stands**
– Used for lifting the vehicle securely to access the strut assembly.
– **Lug Wrench**
– A cross-shaped or socket-style tool designed to remove the wheel lug nuts.
– **Socket Set**
– A variety of sockets (typically metric sizes) to remove bolts and nuts from the strut assembly.
– **Torque Wrench**
– Ensures that all bolts are tightened to the manufacturer’s specified torque settings.
– **Strut Spring Compressor**
– A tool used to safely compress the coil spring on the strut assembly before disassembly.
– **Pry Bar**
– Helpful for leveraging components apart if they are stuck.
– **Hammer**
– Can be used for tapping stuck components free.
– **Penetrating Oil**
– To loosen rusted or stubborn bolts.
– **Safety Glasses and Gloves**
– For personal safety during the replacement process.
### Replacement Procedure
– **Preparation and Safety**
– Park the vehicle on a flat, stable surface.
– Engage the parking brake and place wheel chocks behind the rear wheels.
– Wear safety glasses and gloves for protection.
– **Remove the Wheel**
– Loosen the lug nuts slightly while the vehicle is still on the ground.
– Use the jack to lift the front of the vehicle and secure it with jack stands.
– Completely remove the lug nuts and take off the wheel to expose the strut assembly.
– **Access the Strut Mounting Bolts**
– Identify the top and bottom mounting points of the strut.
– The top mount is usually located under the hood, while the bottom mount is at the wheel assembly.
– **Remove the Strut Assembly**
– First, remove any components obstructing access to the strut, such as brake lines or sway bar links. Use penetrating oil to help with stubborn bolts.
– Unscrew the bolts holding the bottom of the strut to the steering knuckle. Keep track of any washers or spacers.
– Support the strut with one hand and remove the top mounting bolts from the strut tower under the hood.
– **Compress the Coil Spring**
– Using a strut spring compressor, carefully compress the coil spring on the strut assembly. Follow the manufacturer’s instructions for safe operation.
– Ensure the spring is evenly compressed and secured before proceeding.
– **Disassemble the Strut**
– Once the spring is compressed, remove the top nut of the strut mount using a socket wrench. This will allow you to separate the strut from the top mount and bearing.
– Carefully remove the spring from the strut assembly and set it aside.
– **Install the New Strut**
– place the new strut into position, ensuring it aligns with the lower mounting point.
– Reinstall the spring onto the new strut, ensuring it is seated properly in the spring seat.
– Remove the spring compressor carefully, ensuring the spring is securely in place.
– **Reattach the Strut Mount**
– Reinstall the top mount and bearing onto the new strut. Tighten the top nut to the manufacturer’s torque specification.
– Secure the bottom of the strut to the steering knuckle with the previously removed bolts
and torque them to specification.
– **Reassemble Other Components**
– Reattach any components that were removed (brake lines, sway bar links, etc.).
– Ensure all connections are tight and secure.
– **Reinstall the Wheel**
– place the wheel back onto the hub and hand-tighten the lug nuts.
– Lower the vehicle from the jack stands and back onto the ground.
– Finish tightening the lug nuts in a crisscross pattern using a torque wrench to the recommended specification.
– **Final Checks**
– Inspect the area for any tools or loose components.
– Test the suspension by pressing down on the front of the vehicle; it should bounce back smoothly.
– Drive the car at low speed to ensure everything is functioning correctly.
### Conclusion
Replacing the MacPherson strut on a Mitsubishi Colt Plus Ralliart is a detailed process that requires care and attention to safety. Always consult your vehicle’s service manual for specific torque specifications and procedures tailored to your model. If you are unsure at any step, it’s advisable to consult a professional mechanic.
A wheel speed sensor (WSS) is a critical component of modern automotive systems, primarily found in vehicles equipped with anti-lock braking systems (ABS), traction control systems (TCS), and electronic stability control (ESC). Its primary function is to monitor the rotational speed of each wheel, providing real-time data to the vehicle’s onboard computer. This information is crucial for ensuring optimal vehicle performance, safety, and stability.
Wheel speed sensors operate based on either magnetic or optical principles. Magnetic sensors typically use a magnet and a toothed wheel, where the sensor generates a signal as the teeth pass by it, creating a frequency that corresponds to the wheel’s speed. Optical sensors, on the other hand, utilize light and photodetectors to measure wheel rotation. The data collected by the sensors is transmitted to the vehicle’s electronic control unit (ECU), allowing it to make immediate adjustments to braking and engine power.
By monitoring wheel speed, the sensor plays an essential role in preventing wheel lock-up during hard braking, which can lead to skidding and loss of control. Additionally, it helps in managing wheel slip, enhancing traction during acceleration, and improving overall handling. A malfunctioning wheel speed sensor can lead to erroneous readings, resulting in compromised safety features and potentially hazardous driving conditions. Therefore, maintaining the proper functioning of wheel speed sensors is vital for vehicle safety and performance.
