In order for your power steering system to operate, it has to connect with the steering shaft. This runs down from the steering wheel, and provides driver input to the power steering system (motion of the steering wheel).
The steering shaft connects with the power steering system at the gearbox, and there are two seals that are used to ensure that dust does not enter, and that power steering fluid is retained. The first seal is just a dust cover, the second seal is the input shaft seal and is responsible for preventing power steering fluid from leaking out.
All seals are subject to wear and tear, and replacement is inevitable. The amount of use and system age are the largest determining factors in how long the seal will last. If you notice excessive power steering noise or a fluid leak, your power steering input shaft seal may be leaking.
Over time and through wear and tear, your power steering input shaft seal can crack and begin to leak. It must be replaced before the leak becomes problematic. Low fluid levels can cause damage to the power steering rack and pump, and the fluid itself is flammable so contact with a hot exhaust system can be dangerous.
Without a working power steering input shaft seal, your system will lose fluid. This can be detrimental to the power steering pump and other components. Have your system inspected and repaired by a one of our expert mechanics if you suspect there are any problems.
