Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety: Ensure the vehicle is secure and use wheel chocks.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all four tires.
Inflate tires to the manufacturer’s recommended pressure, usually found on a sticker inside the driver’s door.
Inspect tires for any signs of damage or uneven wear.

3. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack stands, pry bar.
Lift the vehicle and secure it on jack stands.
Visually inspect struts, shocks, and bushings for signs of wear or damage.
Replace any worn components with OEM parts:
- Remove the damaged strut or shock by unbolting the upper and lower mounting points.
- Install the new strut or shock and torque to manufacturer specifications (usually around 30-50 ft-lbs).

4. Wheel Alignment Adjustment

Tools Required: Alignment machine (or visit a professional alignment shop).
After replacing any suspension components, take the vehicle to a professional for a full wheel alignment.
Ensure that all alignment angles (camber, caster, toe) are set within manufacturer specifications.

5. Steering Linkage Inspection and Repair

Inspect the steering rack and tie rod ends for wear.
Replace any damaged tie rods or steering components:
- Remove the cotter pin and nut from the tie rod end.
- Use a tie rod removal tool to separate the tie rod from the steering knuckle.
- Install the new tie rod and torque to manufacturer specifications.
