Differential Service in St. Peter, MN – What You Need to Know

Scratching your head? Don’t worry, if you don’t know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in St. Peter, MN, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some St. Peter vehicles might even have two or three.

Not surprisingly, a differential’s job is to compensate for differences; specifically, they’re the differences in wheel speed when turning. For instance, imagine taking a corner near your St. Peter, MN, home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, St. Peter residents’ tires would scrub and hop along the pavement during turns like the early cars.

Ever noticed the big bulge in the middle of the rear axle on trucks? That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. A front-wheel drive vehicle’s differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complex to some St. Peter drivers – but you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but- we’ve said it before – they need to be properly lubricated in order to stay strong. So from time to time, you need to schedule a differential service in St. Peter at Autotronics of St. Peter. The used fluid is drained and replaced with clean fluid. Some advise certain differentials to have special additives installed.

Catalytic Converter Replacement

Many of us have become aware of how important it is to keep our planet’s air clean, and your vehicle has a key component that helps do just that: the catalytic converter. It’s in the exhaust system, and its job is to superheat unburned, harmful byproducts in the exhaust, so they don’t get spewed out into the atmosphere.

There’s another important purpose the catalytic converter has: it improves your vehicle’s efficiency.

Most of us don’t give the catalytic converter much thought until it breaks or someone steals yours, something that’s been happening much more frequently in recent years. The reason people steal them is that catalytic converters use precious metals such as platinum, palladium, and rhodium to do their job. So, they contain valuable materials thieves can sell.

The most likely reason you will have to replace your catalytic converter is age. The more distance your vehicle travels and the more hours your engine runs, it’s putting wear and tear on the converter. T

You can tell if your catalytic converter is failing by looking out for these signs:

Smell of rotten eggs inside your cabin or outside near the exhaust
Check Engine light is on
Vehicle power isn’t what it used to be, or fuel economy has plunged
Vehicle backfires

If you need a new catalytic converter, it can be replaced with an original equipment part if it’s available, or an aftermarket converter can be welded into the exhaust pipe. It’s not uncommon for oxygen sensors to need replacing as well. The technician will also check for other problems in your powertrain that may have contributed to your converter failing.

Check to see if an emissions test is required where you live. If it is, you will have to have a properly functioning catalytic converter to pass it.

Steer Me Right! (Failing Power Steering Hose)

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank. Engineers have figured out a way to take some of your engine’s power to help you turn. Without it, steering can be quite a chore. New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it’s wise to keep them working the way they should so you don’t find yourself stranded without power steering.

Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily. It’s that pressure that presents the challenge. After your vehicle’s seen a few years on the road, you may find your steering isn’t quite as easy as it was. You may hear a groaning or humming sound when you turn.

One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism. The hose is made of rubber and can leak, crack, get damaged by heat and debris or just get too old. If yours is ten years old or older, it’s likely getting close to the end of its life.

If you think you can just wait until it fails completely, think of these possible consequences. If the hose or a coupling fails, power steering fluid can blow all over the hot engine. That fluid is flammable and can start a fire. Or if you’ve been driving for a few weeks with low power steering fluid, that could ruin your power steering pump. Replacing the pump is an extra expense you can probably live without.

A technician will replace the necessary parts and make sure air and contaminants are bled or flushed from the system. Then, he or she will check for leaks. Just think how important a properly working power steering system is for safe operation of your vehicle. Make sure you keep yours in top shape for your safety’s sake and the safety of others on the road around you.
