Automotive Tips from Matt Davis Auto: Where Should New Tires Be Placed

Posted June 30, 2019 10:12 AM

When Garner drivers need to replace tires, they need to know how many they should get and on which axle they should be placed. Replacing a damaged tire may leave you with three others with significant wear, which could affect your traction control, stability control and anti-lock brake systems.

If you can’t afford to replace all four tires at once, you should at least replace two on the same axle. New tires should always be put on the rear axle for stability in slippery conditions. Your friendly and professional Matt Davis Auto tire professional can help you know when your worn tires should be replaced, if you can have a damaged tire repaired as well as selecting the right tires for your needs.

The Matt Davis Auto Guide to Caring for Your Transmission

Posted June 23, 2019 7:41 AM

Most vehicles have automatic transmissions, yet a lot of Garner drivers only have a fuzzy understanding about what a transmission does. Think back to the last time you rode a bike in Garner. You started out in a lower gear and shifted to higher gears as you went faster. Down shift for hills, stuff like that. Think of your legs as the engine – there's an ideal speed you can pedal and you change gears to leverage the work you're doing.

Lower gears for power on hills or for starting out. Higher gears for more speed. That's what the automatic transmission does – it automatically starts in lower gears and shifts up to higher gears to go faster on NC roads. And it automatically shifts back down to climb Garner hills, pass or start up again.

Vehicle automatic transmissions have certainly gotten more sophisticated in recent years. They have more speeds than before: the base is four speeds, five is very common.

At Matt Davis Auto, we routinely service transmissions with six speeds and several have seven or even eight speeds. As you can imagine, this means more parts. Any they all have to fit into roughly the same space.

Transmissions are computer controlled these days, with some high end transmissions having two or three computers. Transmissions are engineered to last. But they are also engineered to tighter tolerances. If a portion of the transmission is starved for lubrication, it can lead to failure.

Not enough fluid can starve the transmission, or dirty transmission fluid can clog small passages in the transmission. Then the lubricant is blocked and can't get to all the parts to protect them, so they wear out prematurely. The technicians at Matt Davis Auto see far too many transmissions that needlessly failed due to neglect.

And, as you can imagine, repairing one of these new transmissions at any Garner service center can be quite costly. That's why owner’s manuals have a schedule for how often you should change the fluid and what type of fluid to use.

It's really important for Garner area drivers to carefully follow the manufacturer's transmission service schedule.

At Matt Davis Auto in Garner, we hope you never become shiftless in Garner because you didn't take care of your transmission.

Power Steering Service in Garner

Posted June 16, 2019 7:09 AM



Most Garner drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine; a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea for Garner drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why power steering fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owner's manual for the right type - or just ask your friendly and knowledgeable pros at Matt Davis Auto in Garner.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so Garner drivers need to replace it from time to time. Many vehicle manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the car maintenance schedule for many of us. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your technician at Matt Davis Auto will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some  warning signs of trouble with your power steering: It's harder to turn the wheel, there's erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump quickly.

Other steering components can be bent or damaged from wear or hard knocks: ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear and an off-center steering wheel. An annual alignment check at Matt Davis Auto in Garner will reveal bent or damaged steering components.

Most SUV's, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. The team at Matt Davis Auto also recommends the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners' manual maintenance schedule. It's usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Garner area, the bearings will need service more often.

Matt Davis Auto Service for Your Exhaust System

Posted June 9, 2019 7:30 AM

Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle.

drive

The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important Garner residents keep their exhaust system in good repair.


The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.

The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn't require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in NC. Call Matt Davis Auto at (919) 600-5125 if you suspect a problem with your catalytic converter.

Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the vehicle engine's computer keep the fuel-to-air mixture at optimal levels.

The muffler is also part of your vehicle exhaust system, but it deals with a different kind of emission. It keeps your vehicle from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.

It is important that damaged mufflers be replaced immediately at your Garner automotive service center, especially if they are leaking. Not only will the extra noise annoy your Garner neighbors, a leaky muffler could be serious.

The entire exhaust system is attached to your vehicle by hangers and clamps. These fasteners can rust, come loose or break. The components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.

Caring for your vehicle exhaust system at Matt Davis Auto yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.

DOG FOOD IN YOUR ENGINE (Keeping Rodents out of your Engine)

Posted June 2, 2019 7:31 AM

A technician was telling us the other day that he was servicing an engine and spotted something he'd never seen before: A collection of dry dog food siting on a horizontal metal ledge near the base of the engine.  It was neatly stashed and was in a spot where the food pellets couldn't have simply fallen down in there.

Even though it's the first time he'd seen dog food in an engine, he immediately knew what was going on.  Critters like mice or chipmunks had found the dog food somewhere nearby and had used the engine as a nice storage unit. 

Mice, squirrels, chipmunks—you name it—like the heat of the engine.  And they'll use that to store up supplies of food for use in cold weather when outside food supplies are scarce.  The problem is they'll also chew on engine components while they're there. And they can do a lot of damage if they start gnawing on the wires.  Depending on how much of your electrical system needs to be replaced, repairs can mount up to the thousands of dollars. 

Those electrical problems can be tricky to track down, too, because the rodents can get to spots technicians don't have easy access to.  Oh, the signs are there; they'll find mouse droppings, acorns… even full mouse nests in your engine.  Yikes.

OK, but even if you get your vehicle fixed, how do you keep the critters from simply setting up their personal pantry again? Here are some things to try:

  • Don't leave any food in your vehicle
  • Get rid of that sweet-smelling air freshener. The rodents can mistake the scent for food and head right for your vehicle.
  • If you have a garage, block all access points for rodents. This can be very hard since they can squeeze through the tiniest spaces you can imagine.
  • Some people keep mothballs under the hood; rodents don't love 'em.
  • Pop the hood every couple of weeks and look for signs of mice: nests, droppings or stored nuts, acorn shells and pet food.

The next time you bring your vehicle into Matt Davis Auto for maintenance or service, your technician will be on the lookout, too. Hey, the dog food belongs in the dog's dish, not supplying fast food for little critters with razor-sharp teeth that can create electrical system mayhem.
