🔧 Murano - Power Steering “Pump” Replacement (Not Applicable: Electric Power Steering)

Your Murano uses Electric Power Steering (EPS), so there is no hydraulic power steering pump, no belt-driven pump, and typically no power steering fluid reservoir to replace or service.

If you’re having heavy steering, noise, or a warning light, the repair is usually diagnosis of the EPS system (battery/charging, fuses, wiring, steering rack/assist motor), not a pump swap.

Difficulty Level: Beginner (checks/diagnosis) | Estimated Time: 0.5-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF and remove the key/fob from the vehicle while inspecting EPS connectors.
• ⚠️ If you disconnect the battery, wait at least 3 minutes before working near airbag/SRS-related wiring.
• ⚠️ Support the vehicle with jack stands if you go underneath—never rely on a jack alone.
• ⚠️ Do not rotate the steering wheel with the intermediate shaft disconnected (can damage the clockspring).

📋 Before You Begin

• Park on level ground, set the parking brake, and use wheel chocks.
• Center the steering wheel and keep it centered during checks.
• If you will unplug EPS connectors: disconnect the negative battery terminal using a 10mm wrench.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm your Murano doesn’t have a hydraulic pump

• Open the hood and look for a power steering fluid reservoir (usually a small plastic tank labeled “Power Steering”).
• On your Murano, you should find no reservoir and no belt-driven pump—that confirms EPS.
• If you see a reservoir, tell me where it is.

Step 2: Check the battery and charging basics (EPS is voltage-sensitive)

• Use a digital multimeter to measure battery voltage at the battery posts.
• Key OFF: if voltage is low, EPS can feel heavy or set warning lights.
• Start the engine and re-check voltage; a weak charging system can cause EPS faults.

Step 3: Scan the EPS system for codes

• Plug in an OBD2 scan tool with Nissan EPS support (specialty) and scan all modules.
• Write down any codes from EPS/Power Steering and also ABS (they can share steering angle data).
• Codes tell you what to test next.

Step 4: Check the EPS-related fuses and connectors

• Use a flat trim clip tool and flashlight to access fuse box covers as needed.
• Use the fuse box cover legend (or owner’s manual) to locate EPS/Power Steering fuses and relays—do not guess locations.
• If you go underneath: raise the front with a floor jack, support with jack stands, then inspect the steering rack area connectors for damage or looseness.

Step 5: Decide the actual repair (there is no “pump” to swap)

• If you have EPS codes, the next repair may be wiring repair, battery/alternator service, or steering rack/assist motor assembly replacement.
• Rack replacement is an advanced job and typically requires a scan tool to calibrate/initialize steering angle after installation.

✅ After Repair

• Clear EPS codes using the OBD2 scan tool with Nissan EPS support (specialty) and re-check for returning codes.
• Road test in a safe area: verify steering assist feels normal and no warning lights return.
• If any steering angle/assist calibration is requested by the scan tool, complete it before driving normally.

💰 DIY vs Shop Cost

Shop Cost: $150-$300 (diagnosis) or $1,200-$2,500 (if steering rack replacement is needed)

DIY Cost: $0-$80 (basic checks) or $600-$1,600 (parts only if rack replacement is needed)

You Save: $150-$900+ by doing it yourself!

Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 1-2 hours to diagnose.

Two quick questions so I can guide the exact fix:

• 1) Do you have a power steering / EPS warning light on the dash?
• 2) What’s the symptom: heavy steering all the time, only at low speed, or intermittent?
