Solution

1. Preparation

Ensure the vehicle is parked on a flat, stable surface.
Gather tools and parts necessary for the repair.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect the shock absorbers for leaks and physical damage.
4. If damaged, remove the upper and lower mounting bolts and detach the shock absorber.
5. Install the new shock absorber, ensuring proper orientation, and torque bolts to manufacturer specifications.
Bushings and Mounts:
1. Inspect all rubber bushings in the suspension for wear or cracking.
2. If any bushings are damaged, remove the components they are attached to.
3. Use a bushing removal tool if necessary to extract old bushings.
4. Install new bushings, applying lubrication if specified, and reassemble the components.

3. Final Assembly

Reattach the wheel and lower the vehicle from the jack stands.
Reconnect the battery if it was disconnected.
Perform a final torque check on all suspension components.
