Toyota Pickup Power Steering Pumps and Parts

Toyota pickup trucks rely on a power steering system to turn the front wheels left or right. A power steering pump is used to move hydraulic fluid and apply pressure to pistons inside the steering system. If you are going to be working on or replacing the power steering pump in your Toyota pickup truck, it will help if you understand how they work and what types there are.

How do power steering pumps work in Toyota pickups?

The power steering pump relies on a number of components to work properly. There is a reservoir to hold the hydraulic liquid for the power steering system. The liquid from the reservoir flows into the spinning rotor inside the power steering pump. The rotor spins around to create enough pressure to force pistons to move in the steering system. The liquid travels from the power steering pump to the pistons via a high-pressure hose. The liquid returns back to the reservoir via a return hose. There is a relief valve on the power steering pump that will pop open if the pressure in the steering system gets too high.

How are Toyota pickup power steering pumps made?

The main difference between the different types of power steering pumps is the mechanism used with the rotor to increase pressure in the system.

  • Vane pumps: Vane pumps consists of a rotor and vanes. The vanes are inserted into slots in the rotor. As the rotor spins around, the vanes push the fluid into the steering system. The vane-styled steering pumps are the most common ones used and come standard in most vehicles.
  • Roller pumps: A roller pump works by cutting V-shaped grooves into the rotor and attaching steel rollers to the rotor. Centrifugal force is applied to the rotor so it can move the fluid out of the pump and into the steering system.
  • Slipper pumps: Slipper pumps use little slippers attached to the rotor. Springs press the slippers tightly against the inside wall of the pump to create a good seal.
