Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack and jack stands, socket set, torque wrench, steering wheel puller, and OBD-II scanner if needed for diagnostics.

2. Inspect and Replace Steering Components

Inspect Steering Linkage:
- Check for worn tie rods and steering rack components.
- Replace any damaged or worn parts as necessary.
Replace Tie Rods:
1. Lift the vehicle and remove the front wheels for better access.
2. Use a socket set to unbolt the tie rod ends from the steering knuckles.
3. Use a tie rod puller to detach the tie rod ends.
4. Install new tie rods by reversing the removal steps, ensuring they are torqued to the manufacturer's specifications.

3. Check and Refill Power Steering Fluid

Inspect Fluid Level:
1. Locate the power steering reservoir.
2. Check the fluid level and condition; top up with the manufacturer-recommended fluid if low.
3. If fluid is dark or contaminated, consider flushing the system.

4. Align and Balance Tires

Perform Wheel Alignment:
1. Take the vehicle to a professional alignment shop to ensure proper alignment.
2. Request a wheel balancing service to address any vibrations.
