Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level against the minimum and maximum markings.
If low, top off with the manufacturer-recommended power steering fluid.
Inspect for any signs of contamination (dark color or debris).

3. Check for Leaks

Examine the hoses and connections of the power steering system.
Look for wet spots or drips around the power steering pump and rack.
If leaks are found, replace damaged hoses or seals as necessary.

4. Inspect Power Steering Pump

Remove any obstructions to access the power steering pump.
Listen for unusual noises while the engine is running and the steering is being turned.
If the pump is noisy, consider replacing it as it may be worn out.

5. Assess Steering Gear and Components

Inspect the steering gear for any signs of wear or damage.
Check the steering linkage for looseness or play.
If damaged, replace the steering gear or associated components.

6. Evaluate CV Joints and Axles

Raise the vehicle using a jack and secure it with jack stands.
Inspect the CV joints for cracks or tears in the rubber boots.
If the joints are damaged, replace the CV axle assemblies.
