Mercedes-Benz Power Steering Line Replacement

Do your Mercedes-Benz steering feel stiff, and you’re constantly adding power steering to your reservoir? Maybe you leak your power steering hoses/lines. Learn how to replace the hoses by following the procedures below.

What you will need

• Power Steering Line
• Floor Jack
• Jack Stands x2
• Mechanic Metric Toolset
  • 17mm Socket

Instructions

1. Jack up the vehicle and secure it with jack stands.
2. Drain the power steering fluid from the reservoir. You will have to suck it out with a syringe or similar.
3. Remove the 17mm bolt at the power steering pump.
4. Get under the car to access the other end of the line. You will be right below the driver’s footwell. Be careful because two lines go to the power steering rack here. The bolts are very close, and you may remove the wrong bolt.
5. Disconnect the wire harness if necessary to make more room.
6. Remove the bolt that secures the power steering line to the steering rack.
7. Install the new line in reverse order. Ensure you install the copper washers, or you will have a PS leak.
8. The bolt that connects to the PS pump has an O ring that needs to go back on.
9. Top off the power steering reservoir.

We had a 2001 Mercedes-Benz that had burned the power steering pump. The problem was that the car was losing power steering and needed to be topped off every week.

Well, eventually, the power steering pump burned, and it needed to be replaced. While replacing the power steering pump, we noticed a large leak in the high-pressure line of the PS pump. You could see a stream of power steering fluid as you moved the steering wheel.
