We're currently in a period of transition in the power steering industry. A variety of different steering systems are still common on the road today, including plenty of cars still using hydraulic power steering units. As recently as 2005, HPS systems were installed in over 50% of cars produced in Europe, Japan, Korea, and North America. While that number is changing today, plenty of those models are still on the road, and in need of service, today.
The power steering hose is a critical piece of the hydraulic power steering (HPS) system puzzle. Not only does it connect the steering pump to the cylinders, allowing for easier turning, but it transfers the pressurized steering fluid into the rack and plays a role in proper system lubrication and cooling. But what happens when an HPS hose fails? And how do you know when to replace it? In this post, we'll discuss HPS hose failure symptoms and maintenance best practices to keep your shop on the right track with every HPS rebuild.
One of the most important parts that protects the inner components that drive a power steering system is the input shaft seal. In order for a power steering system to operate, it must connect with a steering shaft. The steering shaft runs from the steering wheel and provides driver input to the power steering system. There are two seals that are used to make sure that dust does not enter while the power steering fluid is retained. The first seal is, quite literally, a dust cover. The second seal is the input shaft seal. This seal is responsible for preventing power steering fluid from leaking. If the seal is damaged, hydraulic fluid can leak from the power steering input shaft and eventually overheat the system or break down all together. So you can see why protecting these units is vital in order to keep your customers' vehicles in tip-top condition. So today, we're going to look at the most foolproof method used to install hydraulic power steering seals.
