Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, socket set, wrenches, alignment machine.
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake before lifting.

2. Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to match the recommended pressure specified in the owner's manual.

3. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Remove the wheels using a socket set.
- Check for any leaks or signs of damage on the shocks/struts.
- If damaged, replace the shocks/struts using the following sub-steps:
  1. Unbolt the strut assembly from the lower control arm and the top mount.
  2. Replace with new shocks/struts and torque to manufacturer specifications.
Check Ball Joints and Tie Rods:
- If wear is detected, replace the ball joints and tie rods:
  1. Remove the cotter pin and nut from the ball joint.
  2. Use a pickle fork to separate the ball joint from the control arm.
  3. Install the new ball joint and secure it with the nut and cotter pin.

4. Perform Wheel Alignment

After replacing any necessary components, perform a four-wheel alignment:
- Use an alignment machine to measure the alignment angles.
- Adjust camber, caster, and toe to manufacturer specifications.
