Solution

1. Preparation

Tools Required: Jack and jack stands, tire pressure gauge, torque wrench, alignment machine, basic hand tools.
Ensure the vehicle is parked on a level surface and turn off the engine. Wear safety gloves and goggles.

2. Adjust Tire Pressure

Sub-steps:
1. Remove the valve caps from each tire.
2. Use a tire pressure gauge to measure the pressure of each tire.
3. Inflate or deflate tires to reach the recommended pressure as indicated on the driver’s door jamb.

3. Perform Wheel Alignment

Sub-steps:
1. Position the vehicle on an alignment rack.
2. Follow the manufacturer’s specifications to adjust the camber, caster, and toe angles.
3. Ensure all adjustments are within the acceptable range.
4. Tighten all bolts to the specified torque values.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Remove any necessary components to access control arms and bushings.
2. Inspect for signs of wear, such as cracks or excessive play.
3. If damaged, replace control arms or bushings as needed, following the torque specifications for reinstallation.

5. Brake System Check

Sub-steps:
1. Remove the front wheels to access the brake calipers.
2. Inspect the calipers for proper operation by checking for any binding.
3. If a caliper is found to be sticking, replace it and bleed the brake system.
