Smooth Operator (Shock Absorbers)

When you are comfortably headed down the road, you may not realize how many of the imperfections in the driving surface are being smoothed out, so you hardly feel most of them.  You can thank your shock absorbers for a lot of that comfort, and it’s important to make sure you keep your shocks in good shape.

Newer vehicles have shock absorbers in the back wheels with another shock absorbing assembly in the front which may also have a spring component as well, called struts.  

Shock absorbers not only keep your vehicle traveling smoothly and comfortably, but they also contribute to its stability.  Increased stability will help you be able to handle sharp turns and sudden stops more easily.  Shocks also prolong the life of your tires because they’ll grip the road more tightly.  And a nice side benefit of that is your tires should last longer.  

After months hitting a lot of bumps on uneven road surfaces, eventually your shock absorbers will start to wear.  You may notice your vehicle begin to sway more when you go around a corner, and it might be more difficult to steer.  Your tires can start to wear unevenly, and the tread may show signs of cupping (flat spots).  

Other signs your shocks could need replacing is when you hit a hard bump in the road and your vehicle continues bouncing more than you remember.  Your shocks may have suffered extreme damage that can causes fluid inside to leak.  

If you notice any of these signs, head on over so we can check things out.  We also recommend you have your shocks regularly inspected so you can take care of problems before you start feeling some of those symptoms of wear.  Your vehicle’s manufacturer usually will include recommendations in your owner’s manual on how frequently you should have shocks inspected.

Don?t Meddle with the Pedal (Brake Caliper Replacement)

If you drive a newer vehicle, chances are it has disc brakes, and one of the components of that type of brake is called a brake caliper.  The caliper allows the pressure from your foot on the brake pedal to eventually move brake pads against discs in your wheels, which then slow and stop your vehicle.  

If you have disc brakes on all 4 wheels, your vehicle will have 4 calipers.  If you have them just on the front wheels, you’ll only have 2 calipers.  Because your wheels and brakes do their work outside and on the road surface, they are exposed to a lot of dirt and debris, as well as enduring heat, cold, moisture and tough treatment in daily driving.  

Your calipers have seals that are susceptible to the heat generated during the repetitive stops in normal driving, which can take a tough toll on those seals. If you drive when your vehicle’s brake pads and rotors are worn, you can ruin your calipers in the process.  

Here are a few signs that a caliper might be failing:  Your vehicle is pulling to one side when you apply the brakes.  Your pedal goes down to the floor when you push on it.  You hear squeaking from the wheels while braking.  You notice brake fluid on the pavement underneath your vehicle after you’ve parked it for a few hours.  

If you are getting any of those warning signs, it’s important to have one of our technicians determine what’s going on.  There are several brake components that contribute to your vehicle’s safe operation, including the calipers, pads, rotors, brake lines and brake fluid.  

Regular brake maintenance is recommended in your vehicle’s owner’s manual to prevent dangerous surprises.  And when you see issues, have your brakes serviced as soon as you see signs of trouble.

Why Maintaining Your Windshield Wipers and Washers Matters (Windshield Wiper and Washer Inspection)

What do mud, bird droppings and frost all have in common? When they’re covering your windshield, they can temporarily obscure your view of the road, leaving you driving blind.  And when you can’t see the road clearly ahead of you, it can be really scary. 

That’s one of the reasons it’s important to maintain your windshield cleaning system, which includes your wipers, blades and washers.  They’re three vital components that work together to ensure you’re clearly seeing what’s going on with the road and drivers around you.

Your wipers are doing the physical work on the surface of your windshield’s glass.  The rubber or silicone is what touches the surface of the glass, and after time and exposure to the elements, wiper blades can get brittle, lose their flexibility, rip and tear to the point where they simply can’t clear the glass.  

What holds the wiper blades close to the glass is important, too.  Conventional blades use a metal frame which holds flexible rubber inserts.  Just the inserts can be changed which keeps replacement costs down.

Another type that’s gaining more popularity is called a beam blade.  It doesn’t have a frame but instead has a stiff beam and blade combination.  Beam blades can conform more snugly to the curved glass used in many recent vehicle designs.  Plus they have a sweeping shape which harnesses the pressure of the air that passes over them to apply more pressure during wiping, especially effective at highway speeds. High-tech rubber wiper blades, what …?! Seriously, they are pretty cool.

If you crossed the conventional frame blade with a beam blade, you’d have the hybrid wiper.  It’s constructed like a traditional wiper with a plastic frame that takes advantage of the aerodynamic shape of a beam blade.

Equally important to your windshield is the washer system since wiper blades simply don’t work on dry glass.  The washers use a pump to shoot fluid on your glass to remove debris, dust and other contaminants. 

All these systems need to always be at the ready since we never know what elements we’ll encounter on the road. Regular inspections and maintenance of your wipers and washers can ensure you’ll be able to see far down the road ahead of you for clearer vision and safer traveling.

Gearing Up (Differential Fluid Service)

You may have never thought about it, but when you turn a corner, the wheels on one side of your vehicle turn at a different speed than the other side.  What is this magic? The answer is something called the differential.  

A differential is a gear box placed between the drive wheels and needs lubrication to work.  Over time, that fluid can become contaminated, reducing its effectiveness. You likely won’t be able to detect any signs that it’s happening, though it may get a little noisier over time. 

If you continue to drive with contaminated and degraded differential fluid, the gears may wear prematurely. That can also contribute to excess wear on the drive-wheel tires.   

Two-wheel drive vehicles have one differential while all-wheel and 4-wheel drive vehicles will have two or three.   Your vehicle’s manufacturer has guidelines on how often you should have the differential fluid changed, and we recommend you follow those.  

Changing the differential fluid is different depending on what model and year of vehicle you own.  Some have a drain plug so the fluid can be removed and replaced.  In others, a cover and gasket on the differential will have to be removed and replaced.  

Because differentials have constantly moving parts, they generate heat.  That’s why some have a vent to help dissipate the heat caused by friction, and sometimes that vent will need replacing.

When you bring your vehicle in for differential fluid replacement, our technician will also inspect the differential for other issues and test drive it to make sure it’s operating the way it should.

In the Red (Why a Vehicle Overheats)

Heat is one thing that can damage a vehicle, especially if a problem isn’t taken care of soon.  Be on the lookout for signs that it’s getting too hot in some parts of your vehicle, starting with the most obvious one: the heat gauge/warning light on your instrument panel.

When you see that heat gauge heading into the H zone or the warning light comes on, it’s often because your engine’s coolant is contaminated or running low.  It’s important to let a pro look at it soon before serious damage is done,

The radiator is another trouble spot that can cause overheating.  It has a fan that needs to run properly, and it needs to be free of debris and dirt. Another radiator trouble spot is the core.  When it gets clogged and coolant isn’t circulating as it should, an overheated engine can be the result. Have your cooling system checked regularly, including its thermostat.

Your water pump is another part of the cooling system that can wear out, and when it’s not working right, your engine can get hot quickly.  It should also be on the list of regularly checked engine components.

Finally, your vehicle has several rubber belts and hoses that play vital roles in making sure the coolant is getting where it needs to be.  It’s important to have those inspected by a technician before they fail and heat starts to build up.

Your vehicle’s cooling system is complex and critical to its operation. Plus, it must be maintained so it does what a vehicle’s engineers designed it to do.  When it comes to your vehicle, cool is cool, hot is not.

Before You Buy a Used Vehicle (Car Inspection before Buying a Used Vehicle)

Before You Buy a Used Vehicle (Car Inspection before Buying a Used Vehicle)

Perhaps this sounds familiar. Your vehicle seems like it’s been around forever, and you’ve decided it’s time to move on.  But when you check the price of new vehicles, the sky-high price tags have you considering a nice, pre-owned one.  

So, you start looking through the ads and find a few prospects.  A couple look great, and the owners say they’re in like-new shape.  But most of us aren’t trained mechanics, nor do we have the equipment to run the tests to determine what’s right and what’s wrong with a used truck, car, SUV or van. 
 
The answer may be to consider having a trained professional perform an independent inspection on the vehicle you have your eye on. Some dealers may conduct their own inspection, but you are best served by having someone not associated with the seller thoroughly check that vehicle you have your eye on.

A technician puts the vehicle up on a lift to look for damage, corrosion or any signs of accidents or flood damage you can’t see when it’s sitting on the ground.  A used vehicle inspection includes checking brakes, wheels and tires, belts and hoses, suspension components and the heating/air conditioning systems.

In addition to inspecting the vehicle visually, the technician can use a professional, full-function scanner to look for codes stored in the vehicle’s memory and diagnose other electrical issues.  It may also show if there have been any warning lights that have come on recently or if someone has wiped the memory to try to hide something.

Unless you are a professional automotive technician, consider investing in a comprehensive, pre-purchase inspection.  No, it can’t guarantee to turn up everything that might fail in the future, but it can be a bargain to have peace of mind that the vehicle you’re considering is worth the considerable investment you are contemplating. It could also give you additional bargaining leverage.
