Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, air compressor.
Check each tire's pressure and adjust to the recommended PSI.
Inspect tire tread depth and condition; replace tires if excessively worn or damaged.

3. Alignment Adjustment

Tools Required: Wheel alignment machine.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Adjust the front and rear toe, camber, and caster angles according to the manufacturer's specifications.
Tighten all adjustment bolts to the specified torque values.

4. Suspension Component Replacement (if necessary)

Tools Required: Socket set, torque wrench, pry bar.
If any components (e.g., control arms, struts, or bushings) are worn, remove and replace them:
1. Remove the wheel to access suspension components.
2. Disconnect any bolts or fasteners securing the worn component.
3. Install the new component, ensuring proper alignment.
4. Torque all bolts to the specifications provided in the service manual.

5. Steering System Check

Tools Required: Torque wrench.
Inspect tie rods and steering rack for wear:
1. If any components are found to be faulty, replace them.
2. Reassemble and ensure all connections are secured and torqued to specifications.
