Your Vehicle's Other Power Plant (Alternator Replacement)

Your vehicle's engine is probably the first thing that comes to mind when you think of a power plant.  But it has another power source that is vital as well: the alternator.

The alternator is what puts out the electricity that powers such things as your lights, power windows, sound system, and navigation.  Maybe you've started seeing those electrical components behaving in strange ways.  Maybe your power windows are going up and down a little bit more slowly than they used to.  Or perhaps your engine doesn't start as easily or is misfiring.  

Other signs of a failing alternator are headlights that are either brighter or dimmer than usual.  If your battery keeps going dead, it could be that the alternator isn't recharging it.  

The alternator has to get its power from somewhere, and in vehicles with internal combustion engines, that power comes from a drive belt powered by the engine.  Sometimes that belt can fail.  If you hear a whining sound, it could mean bearings in the alternator aren't turning as freely as they used to. You could even notice a burning smell.  Oh, and when you see your battery light illuminated on your dash (it looks like a rectangle with a - and + inside), it may be warning you that your alternator is not healthy.

Bring your vehicle in to us for a diagnosis if you notice any of these symptoms.  If your alternator is bad, we can recommend a new or remanufactured one to replace it.  Some new alternators are warranted for life and remanufactured units usually are guaranteed as well.  

It's important to your vehicle's health to have its alternator putting out the right power consistently.  It may not be as well known as the other power plant under the hood, but it's a vital part of helping your vehicle run the way it is designed to.

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!

Out of Joint (CV Joint and Boot Replacement)

If you have a front-wheel-drive vehicle, it has components called CV joints which enable you to turn your wheels smoothly. The CV stands for “constant velocity.” In essence, it’s a set of gears that connect a shaft that allows power from the transmission to be sent to the wheels.  When you turn the wheels, no matter what angle, the input velocity rotation will be equal to the output. Thus, the name, CV (constant velocity) joint. Other vehicles with 4-wheel drive and all-wheel drive also use CV joints.  

If one of your CV joints isn’t working right, you may find your vehicle difficult to handle.  If one breaks, your vehicle may stop moving.  So, it’s important that CV joints be in top working condition.  The joints need a lot of lubrication, so they are surrounded by grease.  There’s a rubber enclosure around them called the boot which holds the grease in and protects CV joints from the elements. 
 
The biggest problems come when one of those rubber boots cracks.  Water and dirt can then get into the joint, causing it to wear down and lose all its vital lubrication.  It’s important to have your CV joints inspected regularly so a technician can spot cracks before the CV joints are ruined.  Sometimes just the boot can be replaced before any major damage is done.  But when the joint does go bad, it must be replaced.  

Signs your CV joint needs changing out? You might hear a clicking sound when you turn if the CV joint is worn out. You might notice some thick, black grease around your wheel or on the pavement where you park your vehicle.  You might also feel your vehicle vibrate when you’re going fast.

If you suspect you might have a bad CV joint, bring your vehicle in so a technician can determine what’s going on.  Keep your CV joints in good shape and reduce the risk of them seizing up at an inopportune time so you can avoid being stranded.

Differential Essential (Differential Fluid Exchange)

What's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels.  The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn).  

Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there.  (Your vehicle may have more than one differential in it depending on the drivetrain.) 

As you can imagine, it's important that the lubricant in those differentials do its job.  Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down.

So, it's important to have the differential fluid exchanged every so often.  Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km-100,000km.  Regular exchange of differential fluid can reduce premature wear of the gears inside.

Scheduled maintenance goes a long way to preventing differential problems, but sometimes when they begin to fail, you may hear the vehicle sounding a little louder than usual where the differentials are located.  

When it comes to changing the differential fluid, some have a drain plug in them. Others require the entire cover to be removed to drain the fluid.  There are often gaskets that must be changed at the same time to make sure there are no leaks.
Now when someone asks you, "What's the dif?" You’ll know how essential the differential is and how to keep it running in top shape.
