Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, wheel chocks.
Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect the battery if working on electronic components.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Safety Warning: Always ensure the vehicle is securely supported before working underneath it.

3. Inspect and Replace Worn Components

Shock Absorbers/Struts:
- Remove the wheel to access the suspension.
- Detach the upper and lower mounting bolts using a socket set.
- Replace with new shock absorbers or struts, ensuring they are torqued to manufacturer specifications (usually around 20-30 lb-ft).
Ball Joints:
- Use a pry bar to detach the ball joint from the control arm.
- Replace if loose or damaged; install the new ball joint and torque the nut to specifications (typically 40-50 lb-ft).
Tie Rods:
- Remove the cotter pin and castle nut from the tie rod end.
- Disconnect the tie rod end from the steering knuckle.
- Replace with a new tie rod and ensure proper alignment; torque to approximately 35-40 lb-ft.
Bushings:
- If bushings are cracked, remove the bolts securing the control arm.
- Use a press or a suitable tool to remove the old bushings and install new ones.

4. Reassemble and Lower the Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically around 80-100 lb-ft).
