🔧 Armada - Power Steering Pump Replacement

On your Armada, the power steering pump replacement procedure depends on which steering system you have and which pump/hose layout is installed. Once confirmed, the job is mostly removing the drive belt, disconnecting the hoses, swapping the pump, then bleeding air out of the system so it doesn’t whine or foam.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Work on a cool engine; hot belts and pulleys can burn you.
• ⚠️ Power steering fluid is slippery and flammable; clean spills immediately.
• ⚠️ Support the truck with jack stands if you raise it; never rely on a jack.
• ⚠️ Keep hands clear of the belt path before any engine start.
• ⚠️ Battery disconnect is recommended if you’ll be near the main fan/engine harness: remove the negative cable first.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels with wheel chocks.
• Open the hood and locate the power steering fluid reservoir (if equipped).
• If raising the front, lift with a floor jack and support with jack stands under the proper front support points.
• Wipe the pump/hoses clean so dirt doesn’t enter the system when lines are removed.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm your steering system (this decides the exact procedure)

• Use a flashlight to verify you have a power steering fluid reservoir and hoses going to a belt-driven pump (hydraulic system).
• If you do not have power steering fluid anywhere (no reservoir/hoses), you likely have electric power steering and the “pump” replacement steps won’t apply.

Step 2: Identify your pressure line connection style

• Use a flashlight to look at the high-pressure line at the pump: it will typically be either a banjo-style fitting (bolt with sealing washers) or a flare fitting (threads into the pump).
• This matters because the seal parts and tightening method differ.

Step 3: Pause here (I need 2 quick confirmations to give the exact OEM-accurate steps + torque specs)

• Question 1: Do you see a power steering fluid reservoir and hoses (hydraulic), or is it electric (no fluid anywhere)?
• Question 2: At the pump’s high-pressure line, is it a banjo bolt connection or a threaded flare fitting?

✅ After Repair

• Do not start the engine until the correct bleeding procedure is followed for your confirmed system type.
• After bleeding, verify no foaming in the reservoir, no whining noise, and no leaks at the pressure/return connections.
