Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Using a hydraulic jack, lift the vehicle and secure it with jack stands.
Remove the wheels to access the suspension components.

3. Remove Worn Components

Control Arms/Bushings:
- Remove the bolts securing the control arm to the chassis and the wheel hub.
- Replace the bushings if they show signs of wear.
Struts/Shocks:
- Detach the top mounting bolts of the strut assembly from the strut tower.
- Remove the lower mounting bolts from the wheel hub.
- Replace the strut or shock absorber.
Ball Joints/Tie Rod Ends:
- Remove the cotter pin and nut from the ball joint/tie rod end.
- Use a ball joint separator to detach it from the control arm or steering knuckle.
- Install the new component and secure it with a new nut and cotter pin.

4. Reassemble and Torque

Reattach all components in reverse order of removal.
Use a torque wrench to tighten all bolts to the manufacturer's specified torque settings.

5. Reinstall Wheels

Mount the wheels back onto the vehicle.
Tighten the lug nuts in a star pattern to the manufacturer's specifications.

6. Lower the Vehicle

Carefully lower the vehicle back to the ground.
