Disconnect the battery to avoid any electrical issues during repairs.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the min and max marks.

Start the engine and listen for unusual noises like whining or grinding.
If the pump is noisy or leaking, it may need to be replaced.

4. Examine Steering Gear and Linkage

Look for signs of wear or damage on the steering gear and linkage components.
Check for loose bolts or connections that may affect steering performance.
If any components are damaged, proceed to replace them using appropriate parts.

5. Check Drive Belt

Inspect the drive belt for signs of wear, cracking, or fraying.
Ensure the belt tension is within specifications; adjust or replace if necessary.
Reinstall any components removed for access.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and turn the steering wheel from lock to lock to purge any air from the system.
Check for proper steering feel and listen for any abnormal sounds during operation.
