Your Hyundai power steering lines and hoses are the way the hydraulic pressure is carried from the power steering pump to the steering box in the front of your vehicle. This is a closed system and any leak will adversely affect its ability to function properly. If a leak occurs in your Hyundai power steering line or hose, a puddle of clear oil will appear under the front of the vehicle on the pavement. If this is seen an investigation to its source should occur immediately. This is because a leak in the power steering line means air will be replacing the hydraulic fluid which will adversely affect this closed loop system. When air enters the lines, the feel on the steering wheel will change for the driver of the Hyundai vehicle. This will be in a stiffening of the turning motion or even jerkiness to it. The process for investigating the leaking of a power steering hose occurs when the system has pressure being applied to so the leaking fluid can be spotted easily. The fluid rushing out of the leak from the power steering hose will appear to be like a small fountain. As the pressure decreases, so does the amount that's being expelled from the hose on your Hyundai. If this is noticed at all, then the immediate replacement of the power steering line should take place. If that does not occur, your hydraulic system will lose all of is fluid and complete power steering lose will occur in a very short period of time. The replacement of this component on your Hyundai can be accomplished by the owner who just has a set of wrenches as tools. Once the new part is on the vehicle, the system needs to be bled before returning to the road.
