Solution

1. Preparation

Tools Required: Jack and jack stands, tire pressure gauge, alignment tool, torque wrench, basic hand tools (wrenches, sockets).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Adjust Tire Pressure

Use a tire pressure gauge to check the pressure in all tires.
Inflate or deflate tires to the manufacturer-recommended specifications (typically found on the driver’s side door jamb).

3. Inspect and Replace Tires (if necessary)

Check for signs of uneven wear or bulges on the tire surface.
If tires are worn beyond acceptable limits, replace them with new tires of the same specifications.

4. Check and Repair Suspension Components

Visually inspect the control arms, bushings, and shocks/struts for signs of wear or damage.
Replace any worn or damaged components with OEM or equivalent parts.
Torque values: Follow manufacturer specifications for all fasteners during replacement.

5. Perform Wheel Alignment

Use a wheel alignment tool to measure camber, caster, and toe settings.
Adjust the alignment to meet the manufacturer specifications.
Safety Warning: Make sure the vehicle is securely supported on jack stands during this process.

6. Inspect and Repair Steering Components

Examine the steering linkage for play or worn components.
Replace any damaged parts, ensuring all connections are tightened to the appropriate torque specifications.
