Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface, engage the parking brake, and lift the vehicle using a jack and jack stands.

2. Inspect and Replace Components

a. Check Struts and Shocks

Inspection: Examine struts and shock absorbers for leaks or physical damage.
Replacement: If damaged, remove the strut assembly:
1. Detach the lower mounting bolts using a socket set.
2. Remove the top mounting nuts from the strut tower.
3. Replace with new struts, ensuring they are torqued to the manufacturer's specifications.

b. Examine Bushings and Ball Joints

Inspection: Inspect control arm bushings and ball joints for wear or damage.
Replacement: If faulty:
1. Remove the wheel and brake components to access the control arm.
2. Use a ball joint separator to detach the ball joint from the steering knuckle.
3. Replace the ball joint and bushings, ensuring they are properly seated.

c. Tighten Loose Hardware

Go through the suspension components and tighten any loose bolts or nuts found during the inspection.
