Below is a step-by-step guide to replacing the main O-rings on the Mopar electronic power steering pump P05154663AB Dodge Durango 3.6L 2014–2015) to stop fluid leaks.

This pump is an electro-hydraulic unit (electric motor + hydraulic pump), so care is required around electronics.

⚠️ Important Before You Start

• Disconnect the battery before touching the pump.
• Power steering systems operate at very high pressure.
• Work clean — dirt inside the pump will destroy it.
• If the electric motor housing is leaking internally, rebuilding may not fix it.

Tools & Supplies Needed

• Basic metric socket set
• Torx bits (typically T25–T30)
• Snap ring pliers
• Small pick set
• Torque wrench (inch-lb preferred)
• Drain pan
• Clean lint-free rags
• Brake cleaner (non-chlorinated)
• Power steering fluid (correct spec for your vehicle)
• Replacement O-rings
• Assembly lube or clean PS fluid

Step 1 – Remove the Pump from the Vehicle

1. Disconnect the negative battery terminal.
2. Remove engine covers and intake components for access.
3. Place a drain pan underneath.
4. Disconnect:
• Pressure line
• Return line
• Electrical connector
5. Remove mounting bolts.
6. Remove the pump assembly from vehicle.

Drain remaining fluid.

Step 2 – Clean the Exterior

Before opening:

• Spray the outside with brake cleaner.

2. Install:
• Cam ring
• Rotor
• Vanes (rounded edge outward)
3. Reinstall thrust plates.
4. Install rear cover with new O-ring.
5. Torque bolts evenly in criss-cross pattern.

(Typical small pump cover bolts: ~80–120 in-lb. Verify for your application.)

Step 7 – Rejoin Pump to Electric Motor

1. Install new large perimeter O-ring.
2. Align dowel pins.
3. Carefully mate hydraulic section to motor.
4. Install housing bolts.
5. Torque evenly.

Step 8 – Reinstall in Vehicle

2. Reconnect pressure and return lines.
3. Reconnect electrical connector.
4. Reinstall removed components.

Step 9 – Refill & Bleed System

1. Fill reservoir with correct fluid.
2. Leave cap off.
3. Turn steering wheel slowly lock-to-lock (engine OFF) 10–15 times.
4. Start engine.
5. Continue slow lock-to-lock cycles.
6. Check for:
• Foaming
• Whining
• Leaks

Top off fluid.

 Pro Tip

Use our Viton (FKM) O-rings rated for hydraulic fluid and temperature. Cheap rubber rings will swell and fail.
