Differential Service

When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels.  The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn. 

That set of gears is called a differential.  In front-wheel drive vehicles, it's by the transmission and called a transaxle.  Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.)

Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer.  Sometimes you'll hear a whir that might change in pitch when you turn.  You may hear clicking sounds when you're moving.  Others describe rumbling sounds coming from underneath during a turn. Another symptom of possible differential problems may be vibrations or shakes the faster you go. 

All of these could be signs that you have problems with a differential. One common cause of differential problems is the gears aren't getting enough lubrication.

These can all have serious effects on your driving.  You may find it hard to turn, or your wheels may lock up. That could put you or drivers around you in a dangerous position. 

It's better to take care of differential problems before they get too serious.  Bring in your vehicle so we can have a technician check yours out.  They can see if there are any differential fluid leaks or failing gaskets.  In some cases, we may recommend your differential fluid be replaced.  And if there are any mechanical issues, some components may need to be replaced as well. 

When your differential is maintained, you'll be doing your vehicle a good turn.

Don't be Fuelish (Signs Fuel Pump is Failing)

A driver of a large SUV loaded with equipment was heading on a 7-hour work trip when he stopped at a gas station to refuel.  When he went to restart his SUV, it turned over but wouldn't catch.  Try as he might, he was never able to get it started again. 

Of course there are many things that can cause those symptoms, but the next day he had his SUV towed to a service repair facility.  Using their test equipment, they were able to pinpoint the problem.  His fuel pump had failed.  The pump, which was located in the fuel tank, had to be replaced, and after awhile he was back on the road, delayed, but happy to be up and running again. 

What had happened is that the pump was not strong enough to deliver adequate  fuel to his engine, vital to being able to start it.  It had delivered just enough pressure in the morning to get it started the first time, but it was on its last legs.  He had been having trouble starting his SUV in the days leading up to this trip, a clue that something was wrong. 

The engine relies on a certain pressure of fuel from the pump to run properly, and there are some other signs to be aware of that your fuel pump may need to be replaced.  If you are putting strain on your engine, such as going uphill or hauling a big load, and the engine sputters, it may be a sign that the pump isn't delivering that consistent pressure.  Another warning sign is if your engine is running hot and then stalls.  That could mean your fuel pump is getting weak.

Sometimes you might notice your vehicle suddenly speeds up on its own or your fuel economy goes from good to poor in a short time.  If your fuel gauge shows you have plenty of fuel in the tank and your engine stalls, that's another possible sign of a failing fuel pump. 

Technicians have special equipment to see where the fuel problems are, and there are many possibilities.  Have your vehicle checked before you're left stranded.  Oh, and one more tip to prolong the life of your fuel pump.  Since it is cooled and lubricated by the fuel in your tank, make sure you keep at least a quarter of a tank of fuel at all times.  Avoid your "low fuel" light going on and you may be helping yourself avoid having to replace your fuel pump.

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.
