Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electronic systems related to steering.

2. Tire Inspection and Replacement

Sub-steps:
1. Inspect tires visually for any bulges, cuts, or uneven wear.
2. If tires are damaged or excessively worn, replace with new tires of the same specifications.
3. Rotate tires if uneven wear is detected and it’s within the service interval.
Tools Required:
- Jack and jack stands
- Tire pressure gauge
- Torque wrench

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle.
2. Place each wheel on a tire balancing machine.
3. Add weights as indicated by the machine to ensure proper balance.
4. Reinstall the wheels and torque to manufacturer specifications (typically around 100 Nm).

4. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect all suspension components for any signs of wear or damage (e.g., control arms, bushings, tie rods).
2. Replace any worn or damaged components with OEM parts.
3. Reassemble all components and ensure all bolts are torqued to the specified values.

5. Wheel Alignment

Sub-steps:
1. After repairs, take the vehicle to a professional alignment shop.
2. Adjust camber, caster, and toe angles to meet manufacturer specifications.
3. Test drive the vehicle post-alignment to ensure steering responsiveness.
