Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Remove Components

Front Suspension:
1. Lift the front of the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels using a socket set.
3. Detach the components requiring inspection (e.g., struts, control arms).
Rear Suspension:
1. Lift the rear of the vehicle similarly and secure on jack stands.
2. Remove the rear wheels.
3. Detach rear struts and any other problematic components.

3. Inspect and Replace

Inspection:
1. Inspect bushings for cracks or deterioration.
2. Check struts/shocks for leaks or signs of damage.
3. Inspect control arms for bending or cracks.
Replacement:
1. If any component is damaged, replace with OEM or high-quality aftermarket parts.
2. Reassemble components in reverse order, ensuring all bolts are torqued to manufacturer specifications.

4. Alignment

After reassembly, perform a wheel alignment to ensure proper handling and tire wear.

5. System Reset

Reconnect the battery and reset any suspension-related fault codes using the OBD-II scanner.
