- Check the ball joints by shaking the wheel while it is off the ground.
- If there is excessive play, replace the ball joints.
Examine the Steering Rack:
- Look for leaks or wear on the steering rack.
- If damaged, consider replacing the steering rack assembly.

3. Adjust Steering System

Alignment Check:
- Have a professional perform a four-wheel alignment to ensure that the steering components are correctly aligned.

4. Refill Power Steering Fluid

If the fluid level was low, top off with manufacturer-recommended power steering fluid.
Bleed the steering system if necessary to remove air pockets.

5. Reconnect Battery
