Duke Goes 4x4s (Maintenance of 4x4 Vehicles)

dukeDuke here and you know DOGS LOVE TRUCKS.  We love going for a drive in the 4X4 any time of the day so today we are going to truck right into 4X4's and maintenance.

 

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow.

But with that added capability comes additional complexity, drive-train components, and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on the pavement.  Here are some of the key things to keep an eye on:

  • Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisors, Matt and Travis will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfer case seal is working properly.  Otherwise, transmission fluid could get in and cause damage that is costly to fix.  Some transfer cases have an electric motor that shifts it through gears, and its connections are often exposed to the elements, making them vulnerable to damage and corrosion.  Proper maintenance will keep those connections working like they should
  • Front and rear differentials—These also have to have the right amount of fluid and should be checked regularly.  Your service advisors can let you know when you need that fluid changed as the owner's manual recommends.  It's important the service is performed correctly with the proper lubricant so it will work the way it is designed to.
  • Brake lines—Those 4x4s practically beg to go into wet spots. They also are great machines to conquer snow: road salt, brine and all.  Moisture, salt, and brake lines are a recipe for corrosion, so brake lines need to be inspected regularly.  There are anti-corrosion sprays or white lithium grease that can retard corrosion.  Remember, getting there is half the fun, but not being able to stop is no fun at all.

So enjoy your 4x4 and what it can do that other vehicles can't.  Just remember that even though it's tough on the outside, it needs special care to keep it going. 

 

Oh, and remember to take care of the environment when you go off-roading, too.

Duke's Differential Service at Allied Auto Works

 

Duke here and today it's all about Differential Service so watch my video and then let's bark about it.

duke

Here at AutoNetTV, we have national viewers, like your neighbors in Los Altos, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Allied Auto Works service advisors Matt and Travis that your differential needs serviced, or it's seen it as an option upon the service menu. Differential service at Allied Auto Works covers a lot of things, so let's first talk about what a differential does.

As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow on Los Altos area roads. Differentials have gears in them that transfer the power from the drive train to your wheels - which is why they're often referred to as gearboxes. The gears need to be very strong to do this work, and they need to be properly protected so that they'll last.

All vehicles in Los Altos have some form of differential. If you have a front-wheel drive car, your differential is sometimes called a transaxle and is located in the front. If you have rear-wheel drive, the differential is in the back of the car. Los Altos auto owners with a four-wheel drive vehicle have a differential in the front and the back - and in the middle as well. The center differential adjusts for differences in speed between the front and rear wheels.

Differential fluid lubricates and cools the gears. Over time, the fluid can get dirty from bits of the gears grinding off. The additives that keep the fluid clean and protect the differential break down over time. So your vehicle manufacturer has scheduled intervals for you to have your differential fluid changed. Talk to your friendly and knowledgeable Allied Auto Works service advisors Matt and Travis if you are not sure about your recommended schedule.

Have a great and free-wheeling day,

Duke  duke

Duke's Does Differential, What Is That and Do You Have One?

DUKEHey it's the Duke here and today on this wonderful Thursday, I bark to you all about the Differential.  You might be asking what is that Duke and do I have one?  Well I am here to help you on this subject.........so let's get barkin'!

 

With front-wheel drive being so common these days in Los Altos, CA, the differential is just taken care of during a transmission service, so most Los Altos drivers don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of Los Altos customers' minds. It's not uncommon for drivers to not know they have a differential let alone know that it needs service.

Call Allied Auto Works in Los Altos at 650.968.7227 for information about differential service, or stop by our Los Altos, CA, auto center at 2073 Grant Road, 94024.

To better understand what a differential does, think about our local Los Altos high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars in the Los Altos, CA area weigh between 3,000 and 6,000 pounds (1,400 and 2,800 kg) – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool.

The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So vehicle manufacturers recommend intervals for replacing your differential fluid.

The professionals at Allied Auto Works will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. Then they’ll replace the fluid and install the additives if necessary.

Your Allied Auto Works service advisors,Matt and Travis can look up the vehicle manufacture's recommended service interval or you can check your owner's manual. Give us a call at 650.968.7227 for more information about your differential service.

Well that is all for today and remember take care of that Differential!

Duke's Differential Service



Duke here and I get a lot customers, like you, from all across the South Bay who write to me with questions or feedback.

One common question I am asked is: What is a differential and what does it do? You may have been told your differential needs service, or seen it as an option up on the service menu. Differential service covers a lot of things, so let's first talk about what a differential does.

As you drive through a turn, your outside wheels and inside wheels turn at different speeds.

Differential fluid lubricates and cools the gears. Over time, the fluid can get dirty from bits of the gears grinding off. The additives that keep the fluid clean and protect the differential break down over time. So your vehicle manufacturer has scheduled intervals for you to have your differential fluid changed.

Differentials are hard working mechanisms, and, along with the gears in a manual transmission, need to be serviced regularly with high-quality, replacement fluid. Your La Honda automotive service advisor can give you more information as to when your next differential service is recommended. You can also ask if they have a record of when the service was last completed.

As with most service intervals, if you are driving under more severe conditions, you will want to service your differential more frequently. "Severe service" conditions are defined in most owners' manuals, and include: frequent starts and stops, short trips, cold weather, hot weather and towing. All these conditions add to the stress of the vehicle and its parts. Also, off-roading in CA can be especially hard on differentials, especially if you cross streams. Proper service will extend the life of your gears and keep them running more smoothly. If you have never had your differential checked, visit contact-us for more information.

Well I hope I was able to help with what  a Differential Service is today!

Cayenne's Drive Train Service at Allied Auto Works

cayTake a ride on the train, the drive train!

Hi Cayenne here and today we will learn about drive train service.

The drive train in your vehicle includes all the essential 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.

Allied Auto Works 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.

Allied Auto Works 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 sedans 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 Allied Auto Works 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 Los Altos 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.

Los Altos car owners would be wise to check with their owner’s manual for recommendations on how often to service their sedan drive train. It’s also good auto advice to check with your personal and trust Allied Auto Works tech as well. You may live in an area in CA where weather or driving conditions require more frequent servicing of the drive train.

If you drive off-road, it is important to service your driveline more often frequently than the typical recommendation. Conditions encountered off-road around the Los Altos area are particularly hard on your driveline.

Good car care at Allied Auto Works in Los Altos always includes taking care of your driveline. Without it, your sedan becomes a very large paperweight.

Allied Auto Works is located at 2073 Grant Road in Los Altos. We provide comprehensive auto repair and maintenance services for residents of Los Altos, Sunnyvale, Mt. View, Cupertino and Los Altos.

Thanks again for letting me bark at you!

Differential Service in Los Altos CA - 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 Los Altos, CA, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three.

Not surprisingly, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner near your Los Altos, CA 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, our 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. Front-wheel drive vehicles’ 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 Los Altos 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 have your differential serviced at Allied Auto Works. The used fluid is drained and replaced with clean fluid. Some auto manufacturers advise certain differentials to have special additives installed.

Get your differential serviced at our Los Altos automotive center:
Allied Auto Works
2073 Grant Road
Los Altos, CA 94024
650.968.7227

Recommendations for the time and mileage interval for servicing your differential, can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your Los Altos, CA Allied Auto Works service advisor or your auto manufacturers owner’s manual for recommendations.

How and where you drive in Los Altos will have an impact as well. If you drive on dirt roads or through streams around Los Altos, CA, you’ll need to service the differential much sooner than if you always stay on expressways.
