NOTE

SUSPENSION SYSTEM II

A hydraulic suspension system is a type of vehicle suspension that uses hydraulic fluid to provide adjustable ride height and stiffness. It typically consists of hydraulic cylinders, pumps, valves, and a control system to regulate fluid flow and pressure, allowing the vehicle's suspension characteristics to be adjusted according to driving conditions or driver preferences.

To remove and replace a suspension system, follow these general steps:

1. Lift the vehicle: Use a jack or lift to raise the vehicle off the ground safely and securely.
2. Remove wheels: Take off the wheels to access the suspension components.
3. Disconnect components: Unbolt and disconnect the various suspension parts, such as control arms, sway bars, and shock absorbers.
4. Remove old components: Take out the old suspension parts from the vehicle.
5. Install new components: Install the new suspension parts, ensuring proper alignment and attachment.
6. Reconnect components: Bolt and reconnect all suspension parts securely.
7. Reinstall wheels: Put the wheels back on the vehicle.
8. Lower the vehicle: Lower the vehicle carefully from the jack or lift.
9. Test drive: Take the vehicle for a test drive to ensure the suspension operates correctly and the vehicle handles properly.

Fault finding

Fault finding, also known as troubleshooting, is the process of identifying and resolving problems or malfunctions in a system. In the context of a suspension system, fault finding involves diagnosing issues such as noise, vibration, uneven tire wear, or handling problems.

To find faults in a suspension system;

1. Visual inspection: Look for obvious signs of damage or wear on suspension components such as bushings, ball joints, and springs.
2. Road test: Drive the vehicle and pay attention to any unusual noises, vibrations, or handling issues.
3. Suspension bounce test: Push down on each corner of the vehicle and release. The vehicle should bounce once and settle. Excessive bouncing may indicate worn shock absorbers.
4. Wheel alignment check: Check the alignment of the wheels to ensure they are properly aligned, which can affect tire wear and handling.
5. Suspension component inspection: Check for leaks, cracks, or loose connections in hydraulic lines or suspension components.

EVALUATION: 1. What is hydraulic suspension system

2. Briefly describe how to remove and replace a suspension system
3. Define fault finding
4. Mention 4 means of fault finding.
