Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level; if low, top off with the manufacturer's recommended fluid type.
Check the fluid's condition; if it appears dark or contaminated, it may need to be replaced.

3. Inspect Power Steering Pump

Locate the power steering pump.
Use a wrench to check for any loose bolts on the pump.
If the pump is noisy or shows signs of leaks, replace it:
1. Disconnect the hoses from the pump.
2. Remove mounting bolts and take out the old pump.
3. Install the new pump and reconnect hoses, ensuring no leaks.

4. Examine Steering Rack

Inspect the steering rack for any visible wear or fluid leaks.
If the rack is faulty, replace it:
1. Disconnect the steering column and tie rod ends.
2. Remove the mounting bolts securing the rack to the frame.
3. Install the new rack, reversing the removal steps.

5. Check CV Joints and Axles

Inspect CV joints for any cracks or tears in the rubber boots.
If damaged, replace the affected CV joint or axle:
1. Lift the vehicle and remove the wheel.
2. Remove the axle nut and disconnect the joint from the steering knuckle.
3. Slide out the old axle and install the new one.
