Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

- If damaged, proceed to replace the affected tie rods.
Power Steering Fluid Check
- Locate the power steering reservoir and remove the cap.
- Check the fluid level; top off with the manufacturer-recommended fluid if low.
- If the fluid is dark or contaminated, perform a fluid flush and replace with new fluid.

3. Suspension Component Replacement (if needed)

Ball Joint Replacement
- Remove the wheel using a lug wrench.
- Use a socket set to detach the ball joint from the control arm.
- Install the new ball joint and torque it to the manufacturer’s specifications.
Alignment Adjustment
- After replacing any suspension components, take the vehicle to a professional alignment shop.
- Ensure the alignment is set to factory specifications.

4. Final Assembly
