Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal for safety.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before starting any inspection.

3. Inspect Suspension Components

Visually inspect the control arms, struts, and shock absorbers for any visible signs of damage or wear.
Use a pry bar to check for play in the ball joints; if excessive movement is observed, replacement is necessary.

4. Tighten Loose Hardware

Check all suspension bolts and nuts, including those on the control arms and sway bar links.
Torque all fasteners to manufacturer specifications using a torque wrench. Refer to the service manual for specific torque values.

5. Replace Worn Components

If any components are found to be worn or damaged during inspection, proceed with replacement.
- Remove the old component using the socket set.
- Install the new component, being careful to align it properly.
- Re-torque all fasteners to specifications.

6. Reassemble and Lower the Vehicle

Ensure all tools are removed from under the vehicle.
Carefully lower the vehicle back to the ground and reconnect the negative battery terminal.
