Solution

1. Preparation

Gather Tools: Obtain a jack, jack stands, tire iron, pry bar, and a torque wrench.
Safety Precautions: Ensure the vehicle is on a flat surface, engage the parking brake, and use wheel chocks.

2. Lift the Vehicle

Jack Up the Vehicle: Use the jack to elevate the front or rear of the vehicle.
Secure with Jack Stands: Place jack stands under the vehicle for safety before working underneath.

3. Inspect Suspension Components

Control Arms and Bushings: Visually inspect for cracks or excessive wear. Use a pry bar to test for play.
Ball Joints: Check for movement by pushing the ball joint with the pry bar; if there is excessive play, replacement is necessary.
Struts and Shocks: Look for oil leakage and inspect the mounting points for rust or corrosion.

4. Replace Worn Parts

Control Arms/Bushings Replacement:
1. Remove the wheel and tire.
2. Unbolt the control arm from the vehicle chassis and the steering knuckle.
3. Replace bushings if worn, using a bushing press if necessary.
4. Reinstall the control arm and torque bolts to manufacturer specifications.
Ball Joint Replacement:
1. Remove the wheel and tire.
2. Unbolt the ball joint from the control arm.
3. Use a ball joint tool to remove the old ball joint and install the new one.
4. Reattach and torque to specification.
Strut Replacement:
1. Remove the wheel and tire.
2. Unbolt the strut from the top mount and lower control arm.
3. Replace with a new strut and ensure proper torque on all fasteners.
