Drive Train Service in Sierra Vista at Arizona Auto and Radiator Repair

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.

Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.

Arizona Auto and Radiator Repair service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise in your wheel wells when you turn, you may have a damaged CV joint. A damaged CV joint should be replaced.

Rear-wheel drive vehicles generally have a transmission in the front of the car and the differential in the back. A driveshaft (it looks like a long tube) connects the transmission to the differential. Some vehicles may have a two-piece driveshaft, which are connected to the differential with universal joints or U-joints. Again, the differential is connected to two half-shafts that go out to the wheels.

Arizona Auto and Radiator Repair service on the drive train on a rear-wheel drive vehicle starts with servicing the differential. It will need its fluid drained and replaced regularly. The seals on the axles should also be inspected for wear or leaks. Leaking or damaged seals may mean the axle needs to be serviced as well. Also, U-joints can wear out. If you hear clunking or feel a jolt when you shift into drive or into reverse, it could indicate a driveline problem.

All-wheel drive vehicles provide power from the transmission to all of the wheels, instead of just to the front or rear. The advantage is that the vehicle can adapt to different driving conditions and transfer more power to the front or back wheels as needed. The disadvantages are that the driveline is more complicated, and the vehicle weighs slightly more.

Many all-wheel drive vehicles are based on a front-wheel drive set-up. They also have a differential in the rear and one in the center of the vehicle that allows power to transfer to the front and rear. A shaft runs from the transfer case to the center differential, and another from the center differential to the rear differential.

Servicing an all-wheel drive at Arizona Auto and Radiator Repair involves servicing ALL of the differentials and inspecting the joints and seals for wear, leaks or damage.

Four-wheel drive vehicles are rear-wheel drive vehicles that have an option to transfer power to the front wheels. In other words, they can be driven as either rear-wheel or four-wheel drive vehicles. These vehicles are specifically designed for the harsh driving conditions Sierra Vista drivers encounter off-road. The driveline in a four-wheel drive vehicle is similar to that of an all-wheel drive vehicle. The center differential, however, is a transfer case. Maintenance requires servicing both of the differentials and the transfer case, as well as an inspection of the joints and seals.

Sierra Vista auto owners would be wise to check with their owner's manual for recommendations on how often to service their vehicle drive train. It's also good auto advice to check with your friendly and knowledgeable Arizona Auto and Radiator Repair service advisor as well. You may live in an area in AZ where weather or driving conditions require more frequent servicing of the drive train.


Good car care at Arizona Auto and Radiator Repair in Sierra Vista always includes taking care of your driveline. Without it, your vehicle becomes a very large paperweight.

Straight and True in Sierra Vista: Wheel Alignment

Most Sierra Vista folks worry about running out of gas or having a breakdown on the side of the road. That is why we practice preventive maintenance on our vehicles — that and to keep our repair bills down. But one important part of preventive maintenance that may get overlooked by drivers in Sierra Vista is a periodic alignment inspection.

Poor alignment causes tires to wear rapidly, unevenly or both. This means they will have to be replaced early, and new tires are more expensive than an alignment check in Sierra Vista. Bad alignment can also cause damage to suspension and steering systems, which can be expensive to repair in Sierra Vista.

Tire wear on misaligned wheels can also lead to blowouts, which are dangerous, can lead to serious accidents and can seriously damage your vehicle. Also, poor alignment itself can be the cause of an accident since the vehicle may not steer properly.

One or more wheels on your vehicle can be knocked out of alignment by running over a curb or a pothole on a bumpy Sierra Vista street. An accident —  even a minor one — that involves a wheel on your car can lead to misalignment. The small bumps and bangs of everyday driving can also gradually put your wheels out of alignment.

If you have had wheel damage to your vehicle, or if you suspect that your wheels are out of alignment, you should get your alignment checked NOW. Any service center will give you that piece of auto advice. But good vehicle care suggests that you also get your alignment inspected on a regular basis. At Arizona Auto and Radiator Repair in Sierra Vista, we can take care of that for you.

Your owner's manual or Arizona Auto and Radiator Repair can give you a suggestion on how often your alignment should be checked. If it doesn't, then once a year is a good rule of thumb. However, if you drive a lot — and especially if you drive on rough surfaces a lot — then you may want to consider alignment more often. Ask the pros at Arizona Auto and Radiator Repair for a recommendation.

If your vehicle is out of alignment, one or more of the wheels is not tracking correctly and will “pull” against the others. Thus, one sign of poor alignment is that your vehicle pulls to one side when you drive around Sierra Vista. Also, if you are driving a straight path and your steering wheel is off-center, that usually indicates an alignment problem.

Sierra Vista drivers should also check the wear on their tires. If they seem to be wearing out too quickly, or if you notice that a tire is wearing on one side more than the other, you should get your alignment checked.

When you get an alignment inspection, your vehicle will be put on a rack and all the parts of the steering and suspension systems will be inspected for wear or damage. The alignment of the tires will be charted and compared to the original factory settings. If no repairs are needed on the steering or suspension systems, the wheels will then be adjusted to bring them back into alignment.

This may seem like a lot of bother for drivers, but it's a lot less trouble than a blowout or an accident. The old adage is good auto advice for all Sierra Vista residents: an ounce of prevention is worth a pound of cure.

So keep on driving, and keep all four tires on the road.

Maintaining Your Diesel in Sierra Vista

Diesel engines have been used extensively in Europe and Asia for many years. They haven't been as common in the Sierra Vista area because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more Sierra Vista diesel-fueled vehicles on the road, especially in passenger cars and SUV's.

Diesels are popular in AZ because they get better fuel economy than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you're not up with the times. That smoke is a thing of the past.

Diesels don't produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in AZ as for other vehicles.

Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from cellulosic waste like wood chips and sawdust. In AZ, we may soon see bio-diesel produced from algae. These fuel sources will lessen Sierra Vista drivers dependence on fossil fuels and may even become truly renewable and sustainable.

Diesel-powered vehicles also perform as well as other passenger vehicles. Most people don't notice a difference in driving one or the other. If you haul heavy loads or tow a trailer around AZ, however, the diesel is a definite improvement.

So, you may be asking, if diesels are so great, why don't all Sierra Vista people drive them? Surely there are disadvantages you haven't told me about. That's true. Diesel engines are heavier than gas engines, and they cost more in AZ. The better fuel economy of the diesel engine is partially offset by the higher purchase price.

Because of higher fuel prices, diesel engines used to be more expensive to drive in Sierra Vista. But now, with higher volatility in the prices of both gasoline and diesel fuel in AZ, that cost difference is less definitive. Whether a diesel or gas engine is more expensive for AZ drivers depends now on the current price of fuel and how far you drive.

Consider also that diesel-powered vehicles have a high resale value in the Sierra Vista area, and the costs of owning and operating a diesel vs. a gas-powered vehicle in AZ becomes a real toss-up.

Preventive auto maintenance for diesel vehicles has also become similar to that of gas-fueled vehicles in recent years. The major difference is that diesels require cleaner fuel, air and oil, so their filters are more expensive than those for gasoline engines. The engine air filter must be changed more frequently as well.

The costs for car care and repairs in Sierra Vista are similar. You may be thinking, wait:  You just told me that filters are more and have to be changed more regularly. True, but that is offset by the fact that diesel engines have a much longer lifetime than gasoline engines. So if you are the type of owner who prefers to hang on to a vehicle for a long time, you will be more than rewarded with a diesel engine.

So if you have been looking for Sierra Vista auto advice on whether to switch to a diesel vehicle or stay with a gas-powered one, then we hope this helps. The answer as to which type of vehicle is better is that it depends on the driver and their driving habits. Now that you know the facts, you can make an informed choice based on your own priorities and needs.

Budget for Maintenance in Sierra Vista

Sometimes busy Sierra Vista residents dream about going back to the “simpler” days of our grandparents. But if you could travel back in time and take a road trip around AZ in a Model T, you might change your mind. The improved designs and quality of today's automobiles have significantly reduced the amount of time Sierra Vista residents spend at the side of the road during breakdowns. With proper maintenance, today's vehicles can stay on the road longer than ever before.

Some of those improvements, however, have led to higher repair costs. For example, older cars often broke down from vapor lock. Gas vaporized while traveling from the gas tank to the fuel pump. No gas, no power. The car quits going. The solution was simple — you just sat by the road until the car would start up again. Today's Sierra Vista drivers would hardly tolerate that kind of inconvenience, and it's likely that yesterday's Sierra Vista drivers didn't care much for it, either. So on today's vehicles, the fuel pump is actually located inside the gas tank. Problem solved. No more vapor lock. The downside is that now it costs a lot more to repair or replace a fuel pump at Sierra Vista area auto service centers.

Sierra Vista drivers certainly should be grateful for the improvements in auto design that keep us off the side of the road, but it comes at a price. Vehicle care in AZ  simply costs more than it used to. So if you think about it, Sierra Vista drivers can avoid many vehicle repairs by preventive maintenance. If we plan for maintenance, we can avoid a lot of costly repairs.

Just a bit of auto advice from Arizona Auto and Radiator Repair: If you like new vehicles and can afford them, then buy them. But if you are buying a new vehicle every few years because you're afraid of the higher repair costs for older vehicles, then you ought to take a second look at the numbers. You can save a lot of money on car payments and AZ auto insurance with an older vehicle and preventive auto maintenance can help you avoid most car repair bills. And if you budget for preventive maintenance you have done at Arizona Auto and Radiator Repair, it can become as routine as a car payment — only a whole lot less!

Cool Breeze: Air Conditioning Service at Arizona Auto and Radiator Repair in Sierra Vista

Most AZ auto owners know that their vehicles need regular preventive maintenance like changing the oil and filters, rotating the tires and refilling the washer fluid. But did you know that your air conditioning system needs routine maintenance as well? Taking care of your air conditioning system can extend its life and prevent costly repair bills.

Why is it important for Sierra Vista area drivers to get routine maintenance on their air conditioning system? First, the refrigerant contains an added lubricant. As the refrigerant circulates through the air conditioning system, its parts are lubricated. This constant lubrication keeps the parts functioning well. But over time, this lubricant is used up, and without it, the parts will eventually seize up and fail.

Sierra Vista folks should understand, however, that the air conditioner will continue to pump out cool air even without the lubricant, so you won't know the system is sick until it actually dies. So good vehicle care includes regularly checking the refrigerant and lubricant in your vehicle air conditioning system and replacing it if needed.

The second reason your air conditioning system needs preventive maintenance is that air and water can get into the system. Air, water and the contaminants they contain will reduce the efficiency of the air conditioning system and can cause corrosion of the system's parts. Keeping the air conditioning system clean is a practice that will extend its life and keep you from losing your cool on hot Sierra Vista days.

How often should you get a routine car air conditioner inspection? It varies from vehicle to vehicle. Check your owner's manual for the vehicle manufacturer's recommendation.

Here's a good piece of advice from Arizona Auto and Radiator Repair for AZ vehicle owners that will extend the life of their air conditioning systems: You should run your air conditioner in the winter every once in a while. This circulates the refrigerant, which lubricates the seals. That way, they won't dry out during cold Sierra Vista weather.
