🔧 Tundra - Power Steering Pump Replacement

On your Tundra, the power steering pump is belt-driven and feeds hydraulic pressure to the steering rack. Replacing it typically involves removing the drive belt, disconnecting the pressure/return lines, swapping the pump, then bleeding air out of the system.

Difficulty Level: Advanced | Estimated Time: 2.5-4.0 hours

⚠️ Safety & Precautions

• ⚠️ Work on a cool engine; keep hands clear of the belt path.
• ⚠️ Power steering fluid is slippery and flammable; wipe spills immediately.
• ⚠️ Support the truck with jack stands if you lift it; never rely on a jack.
• ⚠️ Wear eye protection when cracking lines loose; fluid can spray.
• 🔋 Battery disconnect is recommended to prevent accidental cranking.

🔨 Step-by-Step Instructions

Before I give the exact step-by-step (with the correct fittings + torque specs), I need 2 quick details so I don’t steer you wrong:

• Does your new pump come with the pulley already installed, or do you need to transfer the old pulley?
• On the high-pressure line at the pump, do you see a banjo bolt (bolt through a round fitting) or a flare nut (a hex nut on the line itself)?

Reply with those two answers and I’ll post the complete, trim-correct procedure with the right tools list and torques for your setup.

✅ After Repair

• Once installed, the system must be bled (air removed) to prevent whining and foamy fluid.
• After bleeding, recheck fluid level, inspect for leaks, and verify steering assist at idle and during a short road test.
