Every minivan on MN freeways has a differential, and it is essential to the proper operation of the vehicle, but most St. Peter auto owners don’t have a clue what it is.

The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the minivan must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.

Have you ever seen the large bugle-shaped object in the middle of the rear axle of a truck? That’s the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV’s have differentials on both the front and the rear axle.

You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You’d be right. But the differential is called a transaxle on a front-wheel drive vehicle because its location allows it to be combined with the transmission.

In an all-wheel drive vehicle, an additional differential or transfer case is located between the front and rear axles. Differentials are strong: They have to be because of the critical job they do. But those tough parts need proper lubrication. You don’t want your differential to seize up. That results in costly damage to your minivan.

So you need to have your minivan differential serviced regularly. It’s not a complicated job. At Autotronics of ST Peter in St. Peter we’ve been servicing differentials for 13 years. The used lubricating fluid is simply drained and then replaced. Some vehicles require specific additives in the differential fluid; your St. Peter service center will ensure you are getting what your minivan needs.

The intervals in time or mileage for servicing your differential vary greatly from vehicle to vehicle. Check with your owner’s manual or Autotronics of ST Peter to find out how often your minivan differential needs to be serviced.

Generally, however, front-wheel drive vehicles need their differential serviced more often than rear-wheel drive vehicles. Also, if you spend a lot of time off-road or on Cleveland area dirt or gravel roads, or if you drive through water, you will need to service your differential more often than the standard recommendation – check with your knowledgeable Autotronics of ST Peter technician.

Preventive maintenance for your differential is good car care that can spare you pricey repair bills. Knowing what your differential is and how it operates is important and will help you understand why this is good auto advice. Remember, take care of your minivan, and it will take care of you.

When St. Peter motorists talk about vehicle safety, they think of tires and brakes. But do we think about our windshields? Isn’t the ability to see a prime safety factor when it comes to driving around MN? Yet we often don’t even notice our windshields until we can’t see through them, or until our wiper blades fail.

It’s estimated that around 46 million people are driving with wipers that won’t keep their windshields clear during a storm — that’s 46 million people with impaired vision during a storm. For safety’s sake, St. Peter drivers need to change the way they think about wiper blades. Most of us, 78% in fact, only change our wiper blades after they fail. In other words, we don’t get new ones until the old ones become a dangerous safety hazard. Instead, we St. Peter auto owners need to make wiper blades an important part of our preventive maintenance routine.

Wiper blades should be changed twice a year, in the spring and in the fall. In MN areas that experience harsh winter weather, special blades are available that prevent ice and snow from collecting on the wiper. Ask your knowledgeable Autotronics of ST Peter technician about wiper blades that repel ice and snow.

No matter what blades you use on your vehicle in the winter, don’t expect them to clear the ice and snow from your windshield after your vehicle has been parked for a while. Using your wipers will shred your blades and may even damage your wiper motor. And don’t drive on St. Peter roads with a frosted windshield. That’s a serious safety hazard. It can cause accidents, and you could be held liable.

Wiper blades are subjected to harsh conditions in St. Peter. They’re out in the Cleveland sun and in the cold. Over time, they become hard and brittle and lose their flexibility. Then they start to tear. Without flexibility, wipers just can’t clear a windshield of water or snow. And torn wipers can actually scratch your windshield. Then the entire windshield has to be replaced — along with the wiper blades. It’s a prime example of how preventive maintenance could have saved you an expensive repair bill.

St. Peter drivers can purchase new wiper blades at an auto service center or at any St. Peter auto parts store. They cost about the same. But the auto service center will throw in the installation.

Once you have good wipers installed, don’t forget to top off your windshield washer fluid. If you take your vehicle in for a full-service oil change at Autotronics of ST Peter in St. Peter, your washer fluid will get topped off then. But it’s good auto advice to purchase a jug of washer fluid to keep at home — just in case. And pack it in the car when you go on long trips.

While we’re on the subject, Autotronics of ST Peter advises St. Peter auto owners to always fill their washer fluid reservoir with window washer fluid. Don’t ever use water. Water can freeze in the reservoir, which can damage it. It can also freeze onto your windshield. Besides, plain water just can’t get a windshield clean. Think about it. Do you use plain water to clean your bathroom mirrors? And a bathroom mirror doesn’t get exposed to anything near the gunk that can end up on your windshield. Windshield washer fluid was designed to do one thing — to clean windshields. Let it do its vital job.

A clean windshield is not just good car care for St. Peter motorists — it’s an essential safety feature. Let’s keep it that way.

We find that a lot of St. Peter service and repair at Autotronics of ST Peter are a little tentative when they talk with their automotive advisors. They want to ask questions, but don’t want to be embarrassed or to seem pushy. Cars are very complicated and there’s more to know about them than most of us have the time to learn. Maybe it’s because cars have become so much more reliable that the average person just doesn’t need to know as much to keep their vehicle on the road.

You know, your local hospital has a Patient’s Bill of Rights that they post throughout the hospital. We think our St. Peter automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.

It’s all about the communication. It’s a little harder when you’re trying to find the right service center in St. Peter. But once you’ve developed a relationship, the communication should come easier.

What are some of the barriers to communication? Well, let’s go back to the medical example. When your doctor’s explaining something to you, it’s something that she understands very well and is very familiar with. So she may use jargon you don’t understand or that you don’t have the education and training that’s foundational to understanding what she’s trying to explain.

So you fall behind and get frustrated.

It can be the same with your St. Peter automotive service advisors. Most of them are very busy trying to service and fix cars to get their customers back on the road. So, just ask when you feel you need more information.

Financial related issues seem to be most frustrating to customers. If you’re not sure, ask what the payment policies are. For example, there’s a big difference between giving your car a quick once over and doing a thorough inspection. Diagnosing a problem may take quite a while. Make sure you know what’s done as a courtesy and what has a fee. Remember, you still have to pay for the office visit even if the doctor says you only have a cold.

Communication is a two way street. If you have some real budget concerns, ask your St. Peter service advisor what he can do. He can give you priorities and options. He can tell you what needs to be taken care of right away for safety or financial reasons. Then you can work out a plan for when to get the rest done. He can also help you with options on the parts. The preference is to always use a high-quality part with a reputation for reliability. But if money is real tight, he might be able to find a rebuilt part or a used part. He should tell you the difference in the guarantee for the part so you can make a good decision.

Ask about warranties for parts and labor. Be sure to get all the paperwork you need to make a possible claim in the future. Your service center and its technicians stand behind their work and want you to understand precisely what that means.

Be sure to ask for and keep a detailed explanation of all the work that’s done on your vehicle. These records will help you keep track of service, warranties and document the good care your vehicle has received when the time comes to sell it.
