Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, clean cloth
Check the power steering fluid reservoir for proper level and condition. If the fluid is low or dirty,:

Remove the steering components (e.g., tie rod ends, ball joints) that show signs of wear or damage.
- Loosen and remove the nuts securing the components.
- Use a ball joint separator tool if necessary to detach the components.
- Install new parts in reverse order, ensuring they are torqued to manufacturer specifications.

4. Wheel Bearing and CV Joint Inspection

Tools Required: Jack and jack stands, socket set
Lift the vehicle and remove the wheels for access.
- Check the wheel bearings for play by moving the wheel back and forth.
- Inspect CV joints for any signs of wear or damage.
- Replace any defective wheel bearings or CV joints as necessary, following proper removal and installation procedures.

5. Alignment and Balance

Tools Required: Alignment tools (if performing alignment yourself)
After replacing any components, take the vehicle to a professional for proper alignment and wheel balancing to prevent uneven tire wear.
