Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools and parts.
Disconnect the negative battery cable to ensure safety.

2. Inspect Steering Components

Tools Required: Socket set, wrenches, flashlight.
Visually inspect the tie rods, steering rack, and control arms for any signs of damage or excessive wear.
Check for loose bolts or connections.

3. Check Power Steering Fluid

Tools Required: Clean rag, funnel.
Remove the power steering fluid reservoir cap and inspect the fluid level.
If low, top off with the recommended fluid type (Refer to owner's manual).
Check for discoloration or contaminants in the fluid; if present, a fluid flush may be necessary.
