How to Replace the Power Steering Pump of a Freightliner

We know you were tired of having to pull full force on the steering wheel and you finally bought that new power steering pump to save you from a needless workout and your Freightliner from more damage. Now, the idea of paying a mechanic a few hundred dollars to replace the old one doesn’t appeal to you, and that’s why you’re here. No further ado, let’s get to work:

 

Tools You'll Need:

  • Socket and wrench set
  • Drain pan
  • Jack and jack stands
  • Power steering fluid
  • Torque wrench
  • New power steering pump

 

1. Ensure safety

Before you get started, park your truck on secure ground and engage the parking brake. Turn off the engine and wait for it to cool down, then disconnect the battery.

2. Drain the power steering fluid

Get the drain pan and place it under the power steering system. Locate the power steering fluid cooler line or a low point in the system, and disconnect it to allow the fluid to drain. Be prepared for some mess here.

3. Disconnect power steering pump

Now that you have the belt off, locate and disconnect the hydraulic lines from the pump. Use a wrench to loosen the bolts securing the pump to the engine block or mounting bracket. Make sure you do this slowly, otherwise you may end up damaging the lines.

4. Remove the power steering pump

Start by locating and unscrewing the mounting bolts securing it to the engine block. Use a socket wrench for this task, and keep the bolts safe for reinstallation. After you removed the bolts just pull the pump away from its mount and disconnect any hydraulic lines attached​. It’s that easy.

5. Install the new pump

Bolt the new power steering pump to the engine block and make sure you torque it to the correct specifications as per your service manual. When you’re done, reconnect the hydraulic lines.

6. Refill with power steering fluid

Fill the power steering reservoir with new fluid, and while the vehicle is still raised, turn the steering wheel left and right several times to help bleed air from the system. Refill the reservoir as necessary.

7.Test the system

Now you can lower the vehicle and reconnect the battery. Start the engine and turn the steering wheel in both directions to check if you did everything right. It’s good practice to check for leaks under the vehicle and verify if the fluid level is correct.

Conclusion

You should be ready to take on smooth rides from now on. To keep your new power steering pump in good condition, make a routine of checking the steering fluid regularly and top it off if necessary. Keep hauling!
