Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Worn Components

Inspect Strut Assembly:
- Use a socket set to remove the strut assembly from the vehicle.
- Check for leaks in the strut; if any fluid is present, replace the strut.
Replace Bushings and Mounts:
- Remove any worn bushings using a bushing removal tool.
- Install new bushings and ensure they are properly seated.
- Torque the bushings to the manufacturer's specifications (typically around 55-65 ft-lbs).
Check Ball Joints:
- If play is detected, replace the ball joint.
- Use a ball joint separator tool to remove the old joint and install the new one.

3. Reassemble Suspension Components

Reinstall the strut assembly using the original bolts, ensuring they are torqued to specifications (usually around 80-100 ft-lbs).
Reconnect the sway bar links if they were removed.

4. Final Checks

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Perform a visual inspection to ensure all components are properly aligned and secured.
