2018 Jeep Grand Cherokee Power Steering Pump Replacement? EPS System Check & Fix Guide
Step-by-step inspection to confirm EPS vs hydraulic steering, scan for codes, and plan the correct repair


đź”§ Grand Cherokee - Power Steering Pump Replacement
On your Grand Cherokee, the steering system is typically Electric Power Steering (EPS), which means there is no hydraulic power steering pump to replace (no belt-driven pump and usually no power steering fluid reservoir).
Before I write pump replacement steps, we need to confirm what you’re working on so you don’t buy parts you can’t use.
Difficulty Level: Intermediate | Estimated Time: 0.5-1.0 hours (verification/inspection)
⚠️ Safety & Precautions
- ⚠️ Turn ignition OFF and keep the key/fob away from the vehicle while working near steering components.
- ⚠️ Disconnect the negative battery cable before unplugging EPS connectors to prevent accidental motor movement and to reduce short-circuit risk.
- ⚠️ If you raise the front end, support with jack stands on proper lift points—never rely on the jack.
đź”§ Required Tools
You'll need the following tools for this repair:
- Safety glasses
- Nitrile gloves
- Flashlight
- Trim clip tool
- 10mm socket
- 3/8" ratchet
- Torque wrench (10-150 ft-lbs range)
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- OBD2 scan tool with Chrysler EPS/ABS access (specialty)

đź“‹ Before You Begin
- Park on level ground, set the parking brake, and chock the rear wheels.
- Center the steering wheel and confirm the front wheels point straight.
- Disconnect the battery: use a 10mm socket to remove the negative terminal and isolate it so it can’t spring back.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm whether your Grand Cherokee has a hydraulic pump
- Open the hood and use a flashlight to look for a round fluid reservoir labeled “Power Steering,” or a cap with a steering wheel icon.
- Use the flashlight to check the front of the engine for a belt-driven pump with two hoses (a thicker low-pressure return hose and a high-pressure line).
- If you do not see a reservoir/pump/hoses, you have EPS and there is no pump to replace.
- EPS uses an electric motor, not fluid.
Step 2: Identify what actually failed (EPS vs. mechanical issue)
- Plug in an OBD2 scan tool with Chrysler EPS/ABS access (specialty) and check for EPS-related fault codes (often stored in ABS/ESC/EPS modules).
- Use a flashlight to inspect battery terminals and main grounds for looseness/corrosion (low voltage can trigger “Power Steering Assist” warnings).
- Use a flashlight to inspect the steering rack area for damaged connectors/wiring.
Step 3: If you truly have EPS, plan the correct repair
- If the scan tool shows EPS motor/module/rack faults, the “pump replacement” equivalent is typically replacing the EPS steering rack assembly (bigger job) or repairing power/ground/wiring.
- If you want, I can write the full DIY steps for the EPS rack replacement, but I need one detail first (see questions below).
Step 4: If you truly have a hydraulic pump (rare on this platform), stop and confirm
- Before buying parts, tell me what you found: reservoir present (yes/no) and pump driven by belt (yes/no).
- If it is hydraulic, I’ll provide the correct pump R&R steps including fluid type and bleeding procedure for your Grand Cherokee.
âś… After Repair
- If you scanned codes, use the OBD2 scan tool with Chrysler EPS/ABS access (specialty) to clear codes and re-check after a short drive.
- Confirm steering assist feels normal at low speed and that no “Power Steering Assist” warnings return.
- If any steering/rack components are replaced, schedule a 4-wheel alignment.
đź’° DIY vs Shop Cost
Shop Cost: $150-$300 (diagnosis) / $1,600-$3,200 (EPS rack replacement if needed)
DIY Cost: $0-$50 (inspection) / $700-$1,800 (parts only if rack replacement is needed)
You Save: $150-$1,400+ by doing it yourself!
Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 1-6 hours depending on what’s actually failed.
