![]() Where a rubber hose transitions to a hard line or where a hard line screws into the rack or pump are the most common. Another common location for a leak is in the hoses or tubing that carry the power steering fluid from the pump to your steering gear or rack. This is usually a relatively inexpensive maintenance item and these leaks can indicate future problems like bearing or pump failures. ![]() ![]() In this case, the best thing to do is replace your power steering pump. If you have a leak here, you will find fluid dripping from behind the pump pulley. The leak would be at the point where the pump shaft exits the pump body and is connected to the pulley. First, your power steering pump itself may leak. No matter what type of fluid used, it always has the chance to leak under the right conditions.īased on the design of your system there are 3 different places you might find a leak. Certain metals will need certain additives in the fluid to inhibit corrosion and the seals used will require the correct fluid for lubrication and wear prevention. Also, the different types of materials used in the system affect the type of fluid required. First, the pump design that your system uses has to match the viscosity of the fluid used. The type of power steering fluid your system uses is dependent on two things. Different power steering systems use different types of fluid to build pressure and power the steering mechanism but the purpose is always the same. The most common issue you find in a power steering system is a power steering fluid leak. Since this system is so simple, it rarely has problems so you rarely think about it. This pump pressurizes hydraulic fluid then pumps it down to the actual mechanism that turns your wheels, either a steering gear or rack and pinion. Hydraulic power steering systems use a pumped attached to the motor of your vehicle and driven by a belt. The hydraulic power steering system in your vehicle is relatively robust so chances are it hasn’t broken before and has never left you working to get your wheels turned. You may have never considered your power steering system, or how it works so your first thought when you find a leak won’t be to check the power steering fluid level. A power steering fluid leak can be one of the most mysterious leaks you can have in your vehicle.
