Removing & Replacing The CV Axle

CV Axle Replacement

For most people, car repair is intimidating and painful. But when you have the experience or a step by step guide, working on the drivetrain can be relatively easy. Alongside a helpful guide, having high quality parts and a good set of tools typically makes car repair a breeze for most people. Removing and replacing a CV axle from the drivetrain can seem like a big job a first, but it is relatively simple once you know how to proceed.

A free day on the weekend, a bit of grease and the right tools is all anyone needs to replace a CV axle. Additional instructions are usually available at the local hardware or parts shop. Employees are generally experienced enough to answer any lingering questions you may have before stating the project. The repair manual and an experienced friend to help are usually the best ways to start off.

Always make sure there’s ample working room around so you can begin to remove some of the components under the hood that are probably in the way. The speedometer drive gears, the control arms and tie rods all typically need to be moved out of the way to access the drivetrain, but every vehicle is different. Always remember to be safe with dangling articles of clothing, sharp edges, heavy or hot components and always use the appropriate tools.

While the automobile is still on the ground, take the wheel cover, the hub cab, the washer and the wheel spindle nut off as well. The next step is to loosen the lug nuts and securely elevate the automobile so it remains level and stable by using a jack or a lift. Always use the parking brake so the car doesn’t move. Take off the tire and detach the stabilizer bar from the suspension. The next step is to dislocate the CV joint from the hub assembly and move it away from blocking the trans-axle. Sometimes a few gentle taps with a mallet or bar will help loosen it up. Now you can remove the CV axle from the trans-axle, use a crowbar with caution if necessary.

Don’t forget to place a new snap ring on the inner axle groove if the car uses one. After that, put grease on the spines at each end of the axle. Align the inner end of the axle shaft up with the trans-axle and push it in until it sets in place. Now install the outer end of the axle shaft back into the hub assembly. Once the CV joint back is in the hub assembly, finish replacing the other components and the project is now complete.

Driveshafts 101: What You Need To Know

Driveshafts

All automobiles have a driveshaft. This is the piece of equipment that transfers the energy created by the energy into the force that drives the wheels. It’s actually a very simple device.

The driveshaft looks like a simple cylinder. What it actually is is an outer tube that protects the shaft itself, which is a spinning cylinder. The frequency of the spin depends on the engine. In addition to automobiles, boats and motorcycles also have driveshafts. Some vehicles may, in fact, have more than one. It is important that the driveshaft balance be maintained.

If your car is rear wheel drive, it will have a long drive shaft that runs the length of the car and then a differential to transfer torque to the wheels, which are connected by short half-shafts. You may sometimes hear a mechanic talk about an automobile’s ‘diff’, shortening the word to something easier to say. A front-wheel drive vehicle has two short shafts, one to each front wheel or, more commonly, a device called a ‘transaxle’, which serves the purpose of the drive shaft, transmission and differential. Obviously, this is reversed in rear-engined vehicles. There are various different arrangements, dependent on the exact configuration. Four wheel drive vehicles have a slightly different configuration again, with front and rear shafts and differentials.

So, what do you need to know about your driveshaft? It’s a moving part and, as such, can fail. Being relatively simple, it is less likely to fail than your transmission (transaxles, of course, are as vulnerable to failure as standard transmission). The most common problem is with the balance of the shaft. An unbalanced driveshaft causes vibration and a loss of power. Race car drivers spend a lot of time worrying about balance because it can make the difference between winning and losing. For the ordinary person, making sure your driveshaft is balanced can help with both power and fuel efficiency. In some cases the universal joints attached to the shaft have to be repaired or replaced.

Common Issues With CV Axles

CV-Axle2

The CV axle is very important to your car. Without it, your vehicle would not be able to move forward or turn. The CV axle provides the flexibility that your car needs while you are driving. You can drive with a bad CV axle for a while, but you need to get the part replaced before you cause severe damage to your vehicle. As long as you keep an eye on the joints, they can last almost the entire life of the vehicle. When you get your tires changed or rotated, have the mechanic look at the axles to make sure they are properly greased and there are no tears.

One of the ways that you can tell your joints might be going bad is if you hear a loud grinding or clicking noise when you turn your wheels. While you are driving on a straight road, you usually won’t hear anything wrong. As the joints gets worse, the noise you hear will get louder. Sometimes, dirt can get trapped in the rubber boot. This can cause grinding, and you might be able to get by with cleaning the boot and greasing it.

A common issue with the part is when the boot gets torn. If the boot is damaged, it cannot keep the grease on the joint. Without the grease, the part will fail. The outer boot normally is the first to break because it is subjected to more wear from driving. If you see grease splatters on the inside of your rims, then you should have the part looked at. At times, the joint could disintegrate and the car could potentially stop moving. If this happens while you are driving, you need to slowly pull the car to the side of the road. Have the car towed home instead of driving it.

CV Joints: What Are They And How Do They Work?

4wd-CV-Joint

Every car in America has only one engine, but four wheels. This creates a problem: how do you deliver power to both axles and all four wheels with only one source of power? The answer is through the use of a complex series of joints to properly transfer the power. Originally this was done by using universal joints, since they allowed the rotational force of the engine to be transferred to any angle. You will still see such connections used to drive the rear wheels on delivery trucks and some off road cars. But it has been noticed since the 17th century that these universal joints do not maintain constant velocity throughout the rotation, which puts stress on the axle and causes it to receive power unevenly. The solution is to develop a constant velocity or “CV” joint, which can deliver power from one shaft to another more exactly.

There are many types of CV joints, but they all do effectively the same thing: they cushion the rotational force of one shaft against another by putting ball bearings or additional connections between the two. This enables the receiving shaft to, ultimately, rotate at the same speed as the powering shaft as it is driven forward by the bearings instead of a direct connection. The bearings transmit the force directly and over time instead of in the indirect and angular method used in older universal connections. This enables a CV connection to deliver more power, more efficiently, and with less wear than traditional connections.

CV-Joint2The CV connection has been used in front wheel drive cars since the 1960s, and it is also used on all four-wheel drive cars. It is necessary to have at least two of these connections in order to deliver power to the front axle, and the use of such adapters allows the axle to “bend” around the passenger compartment. They are also essential in rock crawlers, off road vehicles and trucks which have been modified for mudding. The high ground clearance of these cars necessitates that the drive shaft be “stretched,” and the use of a CV in the right spot can ensure that the drive shaft is properly angled and able to maintain a proper angle and connection as the truck moves over rough terrain.

At Rocky Mountain Driveline, we offer the best constant velocity connections and products for your vehicle. We can help you pick out what is best for the sort of drive line arrangement you want to have, and help you plan out how your drive line may change if you have your vehicle lifted or lowered. We also offer reconstructed constant velocity connections of all sorts, so you can get the best prices on the best products.

Signs Your Driveshaft Is Failing

Jeep-Front-DriveshaftThe driveshaft is an important element of your vehicle that rotates and delivers power to the engine and gears that turns the wheels of the automobile. In addition, it creates torque that makes the car go. It also stops the vehicle. A car cannot function without its driveshaft.

Generally, they do not break down all at one time. It’ll begin to wear and tear over time. Fortunately, there are signs that indicate there is trouble. One of the most common symptoms is vibration. The entire car or parts of the car may begin to shake. The floorboard is one of the common areas where trembling or vibrations may be felt.

Another common sign of trouble are squeaking sounds that get louder when the speed is increased. The sound may go away when the vehicle is going fast and may come back when the car slows down or comes to a stop. If this occurs, it could mean that the U-joint, which is connected to the drive shaft, is damaged.

Turning issues can also be an indication of a problem. If the car’s wheels are not turning properly or resist when the car is turning the corner, most likely it is a sign that the drive shaft needs repair. DriveshaftAnother sign of possible trouble is difficulty turning the wheels when parking in tight or close spaces.

Driving an automobile with a defective or damaged driveshaft is potentially dangerous. If there is any sign of trouble, the car should be taken in to a certified mechanic for immediate inspection for repair or replacement. Replacing or repairing a drive shaft can be very expensive. If the problems are detected early and dealt with in a timely matter, however, the cost for repair or replacement may be significantly lower.

It is highly advised to be on the lookout for any of these and other signs of trouble to keep your vehicle in top running condition. For those in the Denver area, visit Rocky Mountain Driveline for the best service in town!

Common Issues With Differentials

A differential is a device that allows the wheels on your auto/automobile to rotate at variable speeds. This is a necessary function that engages when your vehicle makes a turn. Regular maintenance can prevent most issues. There are a few common differential issues that can cause your auto/automobile problems and may require repairs or maintenance work.

Dodge-Differential

Rear differential leak.
Differential leaks often occur on high mileage auto/automobiles. Over time, the sealing surface of the differential can develop cuts that lead to fluid leaking out of the axles. To find the leak, you will need to look under the vehicle and raise it up with a jack. Before attempting to make repairs, be sure you are equipped with the proper tools. You will need a drain pan, a wrench and a can of rear differential fluid. Remove the bolts and drain the fluid into the pan. By replacing the fluid, you can more effectively monitor the leak. Replacing the differential fluid should be a regular part of your auto/automobile maintenance.

A damaged ring and pinion.
This typically happens with off road vehicles as a result of getting stuck in mud or other substances. The teeth of the differential have a tendency to break off. Additionally, parts of the differential can break as a result of spinning tires.

Noisy differential.
Noise coming from the differential is often a sign that something is wrong. However, there are a few different situations that can lead to a ring and pinion noise. If the ring and pinion was previously quiet and suddenly began making a loud noise, the gears are most likely wearing out. If the gears make noise during acceleration, you may be dealing with a lubrication issue. Another situation that may cause noise is when the pinion is spinning but the tires are stopped. A broken gear can immobilize the differential and cause a loud crunching sound. Regardless of the sound, if your differential makes noise, there is usually a reason. If you are uncomfortable performing repairs, seek a qualified mechanic to diagnose the problem.

A broken axle.
A broken axle is usually easy to diagnose. After the axle breaks off, you should be able to pull the axle out without removing any bolts. In some cases, the broken axle may fall out on its own.

A burned ring and pinion.
The ring and pinion on your vehicle can sometimes become too hot and parts of the surface teeth get burned off as a result. This is typically caused a lubrication failure. You did not put enough oil in the differential. It is important to perform regular differential maintenance to prevent these types of failures.

Flywheel Resurfacing

The flywheel is an integral component of any automotive device. Flywheel-ResurfacingThis mechanical gadget is responsible for various key functions in an automobile. For instance, they claim responsibility for the provision of continuous energy in your vehicle. It also ensures that the orientation system is at par. The mechanical device is also responsible for the delivery of energy at fast rates. Due to these immense responsibilities, this spare part is expected to be prone to wear and tear.

This is why resurfacing is necessary; to prevent it from affecting other devices in your automobile. The perfect time to resurface the flywheel is before the installation of the clutch. This is necessary to prevent immediate damage to the latter. Damages would usually manifest themselves in the form of vibrations and chatter. There are certain signs that would warrant the need for resurfacing.

Such signs include hard spots that have discolorations, warping and an uneven texture. As concerns warping, there are some levels that would warrant your immediate attention. To ascertain this, you can use the feeler gauge to measure the extent of warping. Resurfacing would be an imminent solution when the warp-age spans over 0.002 inches of the flywheel diameter.

How To Resurface The Flywheel

The resurfacing process encompasses two techniques, namely grinding and cutting. The latter method involves the use of brake lathes. This is a process that requires astute planning and care to ensure it works out to perfection. Setting up the rotational device on the lathe normally takes time.

On the other hand, grinding encompasses the use of a grinding machine that consists of a block and head. Alternatively, you can resurface this device using a flywheel grinder. Its overhead stone rotates the device during the grinding process. Resurfacind-FlywheelThis produces a flat, smooth feel, which removes a small amount of metal. This is unlike the cutting process where there is always the possibility of removing a lot of metal. The grinding process usually takes a maximum of four minutes.

Other Important Parts

As you resurface, do not forget other tidbits related to the clutch. You must invest in other parts like the disk, release bearings and pressure plates. You could even replace the bushing or pilot bearing if necessary. These parts are integral to the longevity of your clutch system. Also, replacing these parts will not make the resurfacing process a waste of time.

There are many auto dealers that specialize in the resurfacing of these devices. The problem with this scenario is that some of them are not up to consumer standards. Rocky Mountain Driveline has set itself apart from this undesirable trend. The Denver-based automobile spare parts company is a leading provider of resurfacing services in America.

Rebuilt Brakes For Your Antique or Classic Car

If you own a classic car, you’re going to have to get the brakes rebuilt eventually. Like death and taxes, brakes are inevitable. Whether your ride is a muscled-up late 1960s big block monster or a pre-1940 traditional hot rod, there has to be a way to get it to stop. Fortunately, a brakes rebuild for your vintage automobile is as close as Rocky Mountain Driveline.

57-Chevy-Bel-Air

At the turn of the century, when automobiles were still in their infancy, brakes were considerably less sophisticated than they are today. Remember that most cars in those days weren’t capable of speeds much greater than 15 miles per hour! The braking systems in these “horseless carriages” were literally a holdover from the days of the horse and cart. A wooden block was used to apply friction to the steel-rimmed wheel of the automobile, actuated by a handle beside the driver. This was bound to change, of course, as steel rims gave way to rubber tires. With the added comfort, convenience and traction, also came the necessity of producing a new, more efficient brake system that wouldn’t melt the vehicle’s tires.

Classic cars after that time used a forerunner of a system still in use today. The drum brake was developed specifically to answer the challenge of the new rubber tire with regards to bringing the horseless carriage to a stop. Drum braking systems on antique cars came in several varieties. One of the first was a drum band brake, which used a band to produce friction against the outside surface of a drum. Another used brake shoes on the outside of the drum. While these were effective for stopping the vehicle under ordinary conditions, they proved ineffective when the roads were wet or dusty. Since most roads in the early 1900s were dirt roads, that meant that drivers were pretty much out of luck regardless of what the weather was doing.

OLYMPUS DIGITAL CAMERA

The modern drum brake came shortly thereafter. Comprised of two shoes, a brake drum, and several springs and levers, drum brakes that had the shoes on the inside of the drum proved to be vastly superior to the previous style. In order to rebuild drum brakes of these early classic cars, having the right parts to perform the work is only half the story. Drum brake systems can be notoriously difficult to service, and if your classic car has been stationary for a while, having an experienced mechanic appraise the condition of the brakes and perform the necessary repairs will save you a lot of hassle and money. One of the biggest problems that do-it-yourselfers might run into is misalignment of the brake shoes and failure to correctly install the drum brake springs. Such problems can lead to cracked drums or shoes, noisy brake performance, and even failure of the brake system.

On some cars, a brake rebuild simply won’t do. For instance, if you’ve recently upgraded the engine of your vehicle, and it produces much more horsepower than it did when it rolled off the assembly line, the stock system may not be able to handle the strain. Drums, while effective, still have limitations. One of those is comparatively weak braking when compared with modern disc braking systems. Fortunately, retrofit kits are available that modify the front drums to discs. In order to make certain that your antique or classic vehicle drives right, professional installation is highly recommended for these kits.

A brake rebuild for classic cars is one aspect of classic automotive maintenance that you should avoid skipping. Keeping your classic car well-maintained not only ensures that it stays in prime condition, but also that it’s safe to take out on those Sunday drives!
