Solution

1. Preparation

Gather tools and ensure the vehicle is on a level surface.
Disconnect the battery to prevent electrical issues during repair.

2. Check Power Steering Fluid

Tools Required: Fluid siphon, funnel, and a clean rag.
Remove the power steering fluid reservoir cap.
Use a fluid siphon to extract a small amount of fluid for inspection.
Check the fluid level and top up with the recommended power steering fluid if low.
Clean any spills with a rag and replace the reservoir cap.

3. Inspect for Leaks

Tools Required: Flashlight and mirror.
Visually inspect the power steering hoses and connections for signs of leaks.
Check around the power steering pump and steering rack for fluid accumulation.
If leaks are found, determine the source and proceed to replace the damaged hoses or seals.

4. Test Power Steering Pump

Tools Required: Pressure gauge and wrench set.
Reconnect the battery and start the engine.
Connect a pressure gauge to the power steering pump output port.
Measure the pressure while turning the steering wheel from lock to lock.
If pressure is below specifications, replace the power steering pump.

5. Inspect Steering Linkage

Tools Required: Jack and jack stands, socket set.
Safely lift the front of the vehicle and secure it with jack stands.
Inspect the steering linkage for any worn or damaged components.
Replace any faulty components, such as tie rods or ball joints.

6. Check Steering Rack and Pinion

Tools Required: Socket set and torque wrench.
With the vehicle still elevated, check the steering rack for excessive play or damage.
If the steering rack is faulty, remove it by disconnecting the steering column and mounting bolts.
Replace with a new or reconditioned steering rack and torque the bolts to manufacturer specifications.
