The most common cause of stiff steering with power fluid is a low power steering fluid level. Power steering fluid helps lubricate the moving parts of the steering system and make steering easier. If the fluid level is low, the pump will have to work harder to circulate the fluid, which can make steering feel stiff.
Air in the Power Steering System
Air in the power steering system can also cause stiff steering. Air can enter the system when a hose is disconnected or if there is a leak. Air can also be introduced when new fluid is added to the system. Air can cause the pump to foam, which can make steering feel stiff.
Faulty Power Steering Pump
A faulty power steering pump can also cause stiff steering. The pump is responsible for circulating the power steering fluid and creating the pressure needed to assist with steering. If the pump is faulty, it may not be able to create enough pressure, which can make steering feel stiff.
Worn Steering Components
Worn steering components can also cause stiff steering. The most common worn components are the tie rods, ball joints, and idler arm. Worn components can make steering feel loose and imprecise.
If you are experiencing stiff steering and you have power steering fluid, it is important to have the system inspected by a qualified mechanic. The mechanic will be able to determine the cause of the problem and recommend the necessary repairs.
