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.

Follow the Bouncing Vehicle (Bad Struts and Shocks)

If you hit a bump in the road and your vehicle just keeps bouncing up and down for a lot longer time than it used to, you may have bad struts and shocks.  They’re the things that help to keep your vehicle’s wheels and tires planted to the road surface.

But they don’t last forever.  With care and depending on where and how you drive, shocks and struts should be replaced at intervals ranging from 50,000 miles/80,000 km to 100,000 miles/160,000 km.  If you drive on bumpy roads with a lot of potholes, that interval will likely be shorter. Rough surfaces can take their toll.

But how do you know if your shocks and struts are doing their job properly? The best way is to have your vehicle checked by a technician.  He or she can inspect the shock absorbers and struts for leaks, corrosion and damage.  Mounts and bushings can also go bad and they should be evaluated as well.  A thorough examination by a technician will also include looking at other suspension parts. Some may contribute to making your vehicle behave the same way if they’re broken, corroded, worn or bent.     

If you need new shocks and struts, your service advisor will make sure that you get those that meet manufacturer’s specifications.  That’s important because they want to make sure you’re getting the handling and performance engineers designed your vehicle to have.

Them’s the Brakes (Brake Rotor Resurfacing)

Your vehicle’s brakes wear out.  It’s inevitable. You’ll notice it when you step on the brake pedal and feel it harder to stop, or there’s vibration when you are braking. 

Most modern vehicles have disc brakes that each use a brake pad that press on a disc (disc brakes!) called a rotor.  The friction between them enables you to stop, and each time you do a little bit of the pad and the rotor wears down.

The original brakes on vehicles used a rotor that was thick enough to last through at least two replacements of the pads.  But vehicle manufacturers who want to save costs and weight now make them thinner, and sometimes the rotors have to be replaced after the first pad replacement.  But not always.

Vehicle manufacturers specify a minimum thickness to provide safe braking.  Sometimes rather than having to have your rotors replaced, they can be put on a lathe and resurfaced.  In other words, the surfaces of the disc can be slightly shaved off so the surface is flat and doesn’t wobble. 

Whenever you bring your vehicle in to have the brakes checked, the technician will measure the thickness of the rotors to see if they can be resurfaced without leaving them too thin for safe braking. If they can, with the right tools and skill, the rotors can be resurfaced.  If not, the rotors should be replaced. 

Discuss the options with your service advisor.  Our service center can recommend replacements that are designed to help stop your vehicle as well as or better than the vehicle’s original rotors.

Either way, keep in mind that keeping your brakes in top condition can supply the margin of safety that may one day save your life or the lives of those around you.
