Easy on the Wheel (Power Steering)

Steering a vehicle these days doesn’t take much effort, but if you got behind the wheel back before power steering was invented, you’d need to practically have the strength of Hercules to turn the wheel.   

The first power steering systems widely available changed everything.  Chrysler introduced its Hydraguide power system in 1951. The “hydra” was for a hydraulic pump. It pressurized fluid that multiplied the force applied to the steering wheel so it was easier to turn the wheels on the ground. That pump got power from a belt attached to the engine, but unfortunately it wasted a lot of energy in the process. Plus, the system of hoses and pumps required a fair amount of maintenance and repair. Some say this system provides the most “natural” steering experience of power systems.

Recently, automakers have turned to electric power steering.  It gets its power from the car’s electrical battery and charging system and uses an electric motor to turn the wheels.  Since it’s not powered by the mechanical energy of your vehicle’s engine, electric power steering increases fuel economy.  Electric power steering also doesn’t require hoses and fluids, meaning there are fewer things that can go wrong.  That means less maintenance. 

There’s a third system that combines both of the others, called electro-hydraulic power steering. In this system, the hydraulic power steering pump is powered by an electric motor and, some say, gives the driver that more natural feel of hydraulic systems.  

Because steering is so important for the safe operation of any vehicle, it’s essential to make sure yours is working the way it should. Different types of systems require different kinds of upkeep. Regular, scheduled maintenance according to the manufacturer’s recommendations should help keep your steering in top shape so you can avoid any sudden steering failures.  Bring your vehicle to us so a technician can inspect your steering system.  And, of course, if you notice any steering problems, make an appointment right away to have those issues looked at.  Now that’s one stop that makes sense!

U and your U-Joints (Lubricate U-Joints)

If your vehicle’s power goes to the rear wheels, then you have something called U-joints in the drivetrain. U-joints are connectors that allow the rotating power from your vehicle’s engine to deliver its power through a driveshaft to make the rear wheels rotate.  You need U-joints because the surfaces you drive on aren’t perfectly flat, and the driveshaft has to allow for some flexibility when you are traveling over uneven surfaces.

As you can imagine, the U-joints have to move and flex a lot as your vehicle is going down the road.  They have bearings in them to allow that flexibility, and those bearings are lubricated when your vehicle is made.  Some U-joints have lifetime lubrication and are not designed to be serviced.  When they fail, they have to be replaced.  Others have grease fittings on them that need periodic lubricating by a technician at intervals recommended by your vehicle’s manufacturer. 

There are signs you can look for that your U-joints need attention.  You may hear a clunk when the gears shift into drive or reverse.  You may feel your vehicle vibrate as you move down the road.  Other signs are leaks at the back of your transmission or a banging sound right before you lose power.  Sometimes, though, if you wait until you notice these symptoms, the U-joints may already be damaged.  

That’s why it’s important that your vehicle’s U-joints be periodically inspected and lubricated.  At the same time, a technician should thoroughly inspect the driveshaft and other connected components.  

Keep your U-joints in good shape, and both of U will continue to enjoy years of reliable transportation.

Steering You Right (Power Steering Fluid Service)

It’s important for safe driving that two of the most important systems in your vehicle work right.  One is the brakes.  The other is the steering.  Nearly all vehicles on the road have some sort of power steering that allows you to direct a very heavy machine with little effort. 

There are two types, hydraulic and electric.  Many newer vehicles have electric power steering that uses an electric motor to make your steering easier.  But there are many vehicles on the road that use a system that has been around for years.  It uses a power steering pump, a cylinder, several valves, and hydraulic fluid to make it easy for you to turn the wheel. 

If you have hydraulic power steering in your vehicle, it’s important to change your power steering fluid every once in a while.  Over time, the fluid gets contaminated with dirt and other particles.  You might notice your steering is loose, maybe harder to turn and makes a low, straining noise. The first step in determining hydraulic power steering problems is to have your fluid checked.  Its color and smell can give a technician clues to any problems. They will recommend changing it if it has signs of being old, such as the wrong color or smell. 

Because steering is such a vital safety feature in your vehicle, the best strategy is to maintain your power steering according to the vehicle manufacturer’s recommendations.  That means periodically, the fluid should be changed.  That will prolong the life of the other steering systems components, such as hoses, seals, valves, and the power steering pump.  During this service, the technician will replace the fluid, bleed the system and check for leaks.  You’ll be back on the road knowing your vehicle is in top shape to steer you right.

Steering You Right (Power Steering Signs of Problems)

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the “good old days.”  Today, we take our steering for granted: until something goes wrong, that is.

Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid.

Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for:

  • A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn.
  • Signs of hydraulic fluid leaking, such as wet spots under your vehicle.
  • The smell of burning oil while you’re driving.
  • Steering wheel hard to turn or vibrating.

If you notice any of these signs, it’s a good idea to have a trained technician check them out.  They may be signs of:

  • Power steering pump going bad
  • Steering rack or gear seals wearing out, causing them to lose hydraulic fluid
  • Broken fluid hose
  • Defective power steering cooler
  • Loss of pressure in the power steering gearbox
  • Worn out steering pump belt
  • Failing electric power steering motor

It’s important to have these checked out sooner rather than later. You need to be able to steer properly in order to drive safely. Plus, some of these problems can cause more serious—and expensive—damage if they’re not fixed.  Power steering is a wonderful feature of your vehicle.  Keep it well maintained and it will steer you right.
