Driving does not need to be that hard, and that is why there are a lot of components created to make the experience easier. One of these car parts is the power steering pump. It is a small hydraulic pump that gets its power from the engine and helps you control the steering wheel without needing much effort. This component has become standard in vehicles since its introduction in 1925, and today, these pumps may use rotors, vanes, or slippers to create pressure in the fluid inside the housing. Once this built-up pressure is released, the steering wheel becomes a lot easier to turn to the left or right. When your steering wheel starts to become stiffer, it is a sign that you have to get a new pump. One brand that you might try is ZF, but before buying its product, let us first take a look at its specifications and performance.
- Remanufactured component
- Sold individually
- Without a pulley
- Without a reservoir
- With power steering core
We tested this component on a 2010 Lotus Evora and a 1991 Audi S4, and here is what we have to say:
- The unit looked quite good. It was just a piece of housing, so we just had to look at the critical parts that could easy deteriorate. The thickness of the power steering pump wall seemed equal all throughout, even at the bends.
- The installation of the component was not really that difficult even without instructions from the manufacturer of the replacement pump. We just had to remove the existent hoses and fittings of the pump, replace the old pump with the new unit, and connect the hoses and fittings back. The entire procedure took only forty-five minutes for each vehicle.
- We drove the two vehicles around and made sure that we would perform a lot of turning of the steering wheel. The control with the steering wheel did not change at all, but we were thankful that it did not deteriorate after the installation. After the drive, we checked for leaks around the pump. Luckily, we found none.
- The unit did not come with a reservoir and a pulley for the power steering. With these components, the power steering system of the two cars would have been a renewed one.
- The manufacturer did not include a puller for the power steering pulley. So, we had to look around for this tool in order to pull out the old pulley from the power steering pump of the Evora and the S4.
- It could have been better if the product came with new hoses and fittings to renew the power steering system of the two vehicles.
For a remanufactured unit, this product is kind of pricey. Some units are even twice the cost of products from other remanufacturers. In addition, the price does not justify its not having a pulley and a reservoir. We really think that it is expensive, so if you are not comfortable with its price, shopping other brands would be advisable.
