🔧 Wrangler - Power Steering Pump Replacement

The power steering pump supplies hydraulic pressure so the steering feels light and smooth. Replacing it means removing the serpentine belt, disconnecting the steering hoses, swapping the pump (and often the pulley), then refilling and bleeding the system to remove air.

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

Assumption: your replacement pump may arrive without a pulley.

⚠️ Safety & Precautions

• ⚠️ Work on a cool engine; belts and fluid can burn you.
• ⚠️ Keep fingers/clothes clear of the serpentine belt path.
• ⚠️ Power steering fluid is slippery—clean spills immediately.
• ⚠️ Support the Wrangler with jack stands if you lift the front for bleeding.
• 🔋 Disconnect the negative battery cable before working near the belt and pump.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Open the hood and let the engine cool fully.
• Use a fluid transfer syringe (a large suction syringe) to pull as much old fluid as possible from the power steering reservoir into a drain pan.
• Disconnect the battery negative cable using a 10mm socket.
• If you plan to bleed with the wheels off the ground, raise the front with a floor jack and support with jack stands.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the intake duct/airbox (access)

• Use a trim clip removal tool to pop any intake snorkel clips (if equipped).
• Loosen intake clamps using an 8mm socket or flat screwdriver head on your ratchet (whichever your clamps use).
• Remove the intake duct/airbox fasteners with a 10mm socket, then lift the assembly out for working room.

Step 2: Relieve serpentine belt tension and remove the belt

• Place a serpentine belt tool or 15mm serpentine wrench on the belt tensioner bolt head.
• Rotate the tensioner to relieve tension, then slide the belt off the power steering pump pulley.
• Tip: take a belt routing photo first.

Step 3: Drain remaining power steering fluid

• Position a drain pan under the pump area.
• Use hose clamp pliers to release the return hose clamp, then pull the return hose off the reservoir or pump (whichever is easiest to access).
• Let the fluid drain, and plug the hose end with a clean rag to reduce dripping.

Step 4: Disconnect the pressure line from the pump

• Clean around the pressure fitting using shop rags so dirt doesn’t enter the system.
• Use a flare-nut wrench to loosen the pressure line fitting (a flare-nut wrench grips more sides of the nut to prevent rounding).
• Remove the fitting and cap/cover the open line with a clean rag.
• Remove and discard the old pressure line O-ring/seal.

Step 5: Remove the power steering pump

• Unplug any nearby clips/retainers as needed using a trim clip removal tool for clearance.
• Remove the pump mounting bolts using a metric socket (commonly 13mm) with a ratchet and extensions.
• Lift the pump out carefully, keeping the pulley from catching wiring or hoses.

Step 6: Transfer or install the pulley (if your new pump doesn’t include it)

• Secure the old pump on a stable surface.
• Use a power steering pulley puller/installer kit (specialty) to pull the pulley off the old pump.
• Use the same kit to press the pulley onto the new pump.
• Press it until the pulley sits flush/aligned like the original so the belt tracks straight.

Step 7: Install the new pump

• Set the new pump in place and hand-start the mounting bolts.
• Tighten the mounting bolts with a ratchet, then final-tighten with a torque wrench to the factory specification.

Step 8: Reconnect the pressure line and return hose

• Install the new pressure line O-ring/seal on the pressure fitting.
• Thread the pressure fitting by hand first to avoid cross-threading, then tighten using a flare-nut wrench; final-tighten with a torque wrench to the factory specification if you have the fitting adapter.
• Reinstall the return hose and secure it with a new hose clamp using hose clamp pliers.

Step 9: Reinstall the serpentine belt

• Route the belt according to the under-hood belt routing diagram.
• Use a serpentine belt tool or 15mm serpentine wrench to rotate the tensioner and slip the belt onto the last pulley.
• Visually confirm the belt ribs are seated in every pulley groove.

Step 10: Reinstall intake parts and reconnect the battery

• Reinstall the intake/airbox using a 10mm socket and tighten the clamps with an 8mm socket.
• Reconnect the negative battery cable using a 10mm socket.

Step 11: Refill and bleed the power steering system

• Fill the reservoir with Mopar-approved power steering fluid (ATF+4 compatible) using a funnel.
• With the front wheels off the ground on jack stands, turn the steering wheel slowly from lock-to-lock 10–15 times with the engine OFF.
• Top off fluid as the level drops.
• Start the engine and let it idle. Turn lock-to-lock 5–10 more times slowly.
• Shut the engine off, wait 2 minutes, then recheck level and top off to the HOT/COLD mark appropriate for temperature.
• Tip: don’t hold full lock more than 2 seconds.

✅ After Repair

• With the engine idling, inspect the pump, pressure fitting, and return hose for leaks using a flashlight and shop rags.
• Verify steering is quiet and smooth (no whining or foamy fluid).
• Recheck fluid level after a 10-minute test drive and top off if needed.
• If the belt chirps or walks, recheck pulley alignment and belt seating.
