Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery (if working on electrical components).

2. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, add manufacturer-recommended fluid.
If the fluid is dark or contaminated, consider a complete fluid flush.

3. Replace Accessory Belt (if worn)

Use a socket set to loosen the tensioner pulley and remove the old belt.
Install the new belt following the routing diagram usually found on the engine bay.
Tighten the tensioner to the manufacturer's specifications.

4. Repair or Replace Power Steering Components (if leaks are found)

Identify the source of any leaks (hoses, pump, or rack).
For hose replacement, use a hose clamp tool to remove the old hoses and install new ones.
If the power steering pump is faulty, disconnect the power steering lines and electrical connector, remove mounting bolts, and replace the pump.

5. Check Drivetrain Components

Inspect the differential fluid; if low, top it off with the appropriate fluid.
If any drivetrain components are damaged (e.g., CV joints), replace them as necessary.
