Differential Service At Autotronics of ST Peter: Viva la Difference

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.

Differential Service At Autotronics of ST Peter: Vive ala Difference 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.

Automotive Detective Work In St. Peter

There’s a reason we use the word “diagnose” when we talk about fixing cars in St. Peter. Figuring out what’s wrong with your minivan has a lot of similarities to figuring out what’s wrong with someone who is ill. Vehicles are a mass of complex systems that can produce a variety of symptoms when something goes wrong. As with human diagnoses, a specific symptom may be indicative of a number of problems, and figuring out the specific cause takes training and experience.

Sometimes the diagnosis of your minivan’s trouble comes down to a matter of trial-and-error. This can be frustrating for St. Peter motorists because time and money are on the line. You may feel you should only be paying for repair work. Of course, you only want to pay for the right repair – and a proper diagnosis is part of getting it right. Like at the St. Peter doctor’s office — some of what you pay for is the doctor’s time and effort to figure out what’s wrong with you, not for the actual cure.

The good news is that St. Peter motorists can do a lot to help out their knowledgeable Autotronics of ST Peter service professional in figuring out what’s wrong with their minivan. Again, the medical office is a good analogy. The more information you can give your doctor about where it hurts, when it hurts and how it hurts, the more quickly he will be able to help you. In the same way, the more you can tell your St. Peter service technician about when the problem occurs, what is sounds like, how often it occurs, where it occurs, etc., the more efficiently he will be able to get you back on the road.

Good auto advice: learn how to talk to your St. Peter tech.

If fluid is leaking from your minivan, you should note the color of the fluid, where under the car the puddles form, and when they form (e.g. only when it’s parked for a while, only if the engine’s hot, when the weather turns cold, etc.). For example, if your minivan is making an unusual sound, you should indicate where the sound is coming from, what kind of sound it is, and when you hear it (again, be very specific). The more details you can give, the more helpful you will be. “I hear the sound when I turn left” is more helpful than “I hear the sound when I turn.” After a few conversations with your Autotronics of ST Peter service professional, you should get a feel for the kind of information he needs.

If you drop your car off, leave a detailed note describing information about your minivan’s problem. A quickly scrawled “Making a funny noise” will only lead to frustration for both your technician and for you. Good communication leads to better car care for St. Peter drivers.

If your minivan is occasionally stalling or sputtering, you may need a little more patience than with other types of car trouble because these types of problems are intermittent. In order to fix the trouble, your tech often finds it helpful to reproduce the symptoms. And if the problem is intermittent, it may take a while to do so.

In these cases, specific information can be invaluable, as it can significantly reduce the time it takes for your knowledgeable technician to get your minivan to misbehave. For example, if you can tell your technician that the vehicle only acts up after it’s been driven for 20 minutes and over 50 mph, it will allow him to quickly reproduce your problem, greatly reducing the time it will take for a car diagnosis in St. Peter and then get it fixed.

Good preventive maintenance goes a long way to keeping your car out of the Cleveland repair shop, but if you need to get it corrected, good communication will get you back on the road quickly.
