However, if you've recently replaced the power steering pump, hoses, or had major work done on the system and are experiencing problems like hard steering or groaning noises, here's what you can try. But be aware, this isn't a guaranteed solution and improper procedure could damage the system.
Before you begin:
* Consult a repair manual: A Haynes or Chilton manual specific to your year and model will be incredibly helpful. It will show you diagrams of the system and any specific instructions.
* Safety first: Wear safety glasses. Power steering fluid is corrosive. Have rags and a drain pan ready.
Steps (if absolutely necessary and only after consulting a repair manual):
1. Check Fluid Level: Make absolutely sure the power steering fluid reservoir is filled to the correct level with the correct type of fluid (check your owner's manual).
2. Start the Engine: With the engine running, slowly turn the steering wheel fully to the left, then fully to the right, repeatedly. Do this several times.
3. Monitor Fluid Level: Keep an eye on the fluid level. If the level drops significantly, you may have a leak somewhere in the system which needs addressing *before* you continue. Top off the fluid as needed.
4. Check for Air Bubbles: If the reservoir has a clear side, you might see air bubbles. Continuing to turn the wheel helps them escape.
If this doesn't work:
It's highly likely there's a more serious issue. Possibilities include:
* Leaking hose or seal: A leak will introduce air into the system constantly. Inspect all hoses and connections carefully.
* Faulty pump: If the pump is damaged, it might not be able to build sufficient pressure, even if there is no air.
* Internal leak: A leak inside the steering gear itself requires professional attention.
Important Note: Bleeding the power steering system usually isn't a DIY-friendly fix. If the simple steps above don't resolve the hard steering, it's best to take your Ranger to a qualified mechanic for proper diagnosis and repair. Attempting to force the system to bleed could damage the pump or other components.
