🔧 Edge - Power Steering Pump Replacement

Your Edge does not use a hydraulic power steering pump. It uses EPAS (Electric Power Assisted Steering), which has an electric motor and control module on the steering gear (rack), so there’s no pump or power steering fluid to replace.

To help you fix the real issue, we need to identify whether you’re dealing with a steering gear/motor problem, an electrical issue, or a front-end/mechanical problem.

Difficulty Level: Intermediate (diagnosis) / Advanced (steering gear replacement) | Estimated Time: 0.5-1.0 hours (checks) / 4-8 hours (steering gear)

---

⚠️ Safety & Precautions

• ⚠️ Support the Edge with jack stands before going under it.
• ⚠️ Keep hands clear of steering/suspension joints while turning wheels.
• ⚠️ Disconnect the negative battery cable before unplugging steering/airbag-related connectors.
• ⚠️ If the steering gear is replaced, the vehicle will require alignment and steering angle/EPAS relearn with a scan tool.

📋 Before You Begin

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the symptom (so you don’t chase the wrong part)

• Start the Edge and note the exact symptom: heavy steering, warning message, noise, pull, or intermittent assist.
• Check the dash for a steering warning (ex: “Steering Assist Fault”).
• If steering is heavy only at idle, tell me.

Step 2: Scan for EPAS/PSCM fault codes

• Plug in an OBD2 scan tool with Ford EPAS/PSCM access (specialty).
• Read codes from the Power Steering Control Module (often listed as PSCM/EPAS).
• Write down any codes and freeze-frame data.

Step 3: Quick mechanical check (rules out binding)

• Lift the front safely using a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
• Remove both front wheels using a 21mm socket.
• Turn each hub by hand and move the steering left/right to feel for binding.
• Inspect outer tie rods and ball joints for torn boots or seizure.

Step 4: If replacement is needed: plan for steering gear replacement (not a pump)

• Steering gear replacement on the Edge is an advanced job and typically requires lowering the subframe and disconnecting the steering intermediate shaft.
• You’ll need a scan tool for post-install setup (relearn/center) and you must get a professional alignment afterward.
• I can give exact steps once we confirm it’s the rack.

✅ After Repair

• Clear EPAS/PSCM codes using the OBD2 scan tool with Ford EPAS/PSCM access (specialty).
• Perform any required steering/PSCM initialization or relearn (scan-tool guided).
• Get a 4-wheel alignment after any steering gear or tie-rod work.
• Road test: verify steering assist is normal and no warnings return.
