Solution

1. Preparation

Gather necessary tools and parts.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Ensure the vehicle is on a level surface and the engine is off.

2. Inspect and Remove Components

Sub-step 1: Check the sway bar links for wear. If damaged, remove the bolts securing the links using a socket set.
Sub-step 2: Inspect the struts for leaks or damage. If necessary, remove the strut assembly by loosening the top mount bolts and lower strut bolts.
Sub-step 3: Examine bushings for cracking or wear. Replace any damaged bushings by using a bushing removal tool.

3. Replace Components

Sub-step 1: Install new sway bar links by aligning them with the sway bar and securing with the bolts. Torque to manufacturer specifications.
Sub-step 2: Replace struts with new units. Ensure proper alignment and torque all bolts to specified values.
Sub-step 3: Install new bushings by pressing them into place. Ensure they are fully seated without gaps.

4. Reassembly

Reinstall any components that were removed during inspection.
Ensure all bolts are tightened and torqued to manufacturer specifications.

5. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Perform a bounce test again to ensure all components are functioning correctly.
