Drive shaft problems

In a front-wheel drive car, the axles are connected to the wheels with Constant Velocity CV joints. These allow the axle and wheel to flex as the car drives to account for turns, uneven surfaces, and more.

However, the joint itself is a weak point in the system. It needs lubrication, and it needs to be protected from dirt, dust, rocks and other debris. If the boot that seals the CV joint is damaged, the grease will leak out and contamination will set in, eventually causing the joint to wear out and fail.

You may lose control of the vehicle entirely. It is not safe to drive with a damaged CV joint. Look for some symptoms of a failing CV joint to have it repaired before it becomes unsafe to operate the vehicle. Busted Boots. If the problem is just a busted CV boot, you might be able to drive for some time before having work done. However, the longer you drive with the boot busted, the more dirt and grime contaminates the joint and the more grease leaks out.

If caught quickly, you can usually just have the boot replacedrather than the entire joint. CV boots are typically checked during regular car inspections — mechanics will always look for any signs of damage. If you hear a clicking, clunking or popping noise from the front wheels, particularly while turning, it means the situation has progressed to the point where the CV joint is damaged. These cannot be repaired — only replaced.

Try to catch a faulty CV joint before this point to maintain safe driving conditions. This is a critical component, and if it fails completely, the situation can be severe and very unsafe.

Also please check out the statistics and reliability analysis of Ford Escape based on all problems reported for the Escape.

While driving our Ford Escape se shortly after being serviced at our local coggin Ford for a maintenance including a transmission flush, the vehicle began to exhibit problems. The vehicle had been plagued with problems since purchase from a used dealer and each time it was brought to Ford who claimed to fix the problem every time. Despite the vehicle being brought to the Ford dealership it continued to have multiple problems which seemed to be misdiagnosed such as a wastegate and turbo that needed to be replaced when the intake hose was simply not reconnected after recall issues were supposedly addressed.

The vehicle would intermittently signal that the coolant level was low. While sitting at a stoplight after normal operation the vehicle failed to engage the driveshaft once the accelerator was depressed.

Is It Safe to Drive With a Damaged CV Joint?

After failing to hear the gears engage the accelerator was released followed by a loud thud and then the vehicle jerked extremely as the gears engaged and the vehicle began to move. The vehicle then felt as if it was not fully catching gears as it began to over rev when attempting to continue driving. Upon this happening the vehicle then engaged a safety mechanism where the vehicle only allowed for it to move far enough for us to pull into a parking lot and shut it off.

A tow truck was called and the vehicle was towed home. This was after getting the vehicle back from Ford whom did a diagnostic stating that the recall issues were taken care of and the transmission flush was completed. Being that the problems had been so repetitious we have left the vehicle parked and no longer drive it due to not being able to afford the cost of a replacement transmission. It is out of warranty and we still owe over 12 thousand dollars on the vehicle.

Now we are stuck with a car payment for a car we can't even drive and this car has been nothing but problems since it's purchase. See all problems of the Ford Escape. The dealer refused to pay for defective driveshafts. The vehicle would shake violently when decelerating. The dealership blamed faulty tires but the tires wer not the problem.

Diagnosing and Servicing Driveline Noises

We had an independent mechanic replace both drive shafts to correct the problem. No reimbursement was offered by dealership and was brought in while under warranty with no help. Consumer writes in regards to defective drive shaft. While driving vehicle it started making a lot of noise and vibrating a lot.

Checked lug nuts and found all tight. Got under vehicle and found the right drive shaft had come apart. Have never had one fail suddenly like this. Had car towed to Ford dealer. Upon inspection the found one of the motor mount bolts had backed all the way out, a second one had backed out a little and broke, the third remained tight but had sheared off.

This allowed the engine to drop drop and destroyed the drive shaft. Bought this vehicle new in Bolts have never been loosened during this time. Dealer has no explanation as to why they would come loose. Mileage at time of failure was I purchased this vehicle from byers kia 9 months ago. I recently just made my 8th payment on it.

Well on Sunday November 3rd my drive shaft quit working. We installed a u joint hoping that would solve the problem.One of the simplest and most important parts of a vehicle is the driveshaft. Responsible for transferring the output of the transmission to the axlesit is essentially a shaft that drives the vehicle.

Though it has a basic function, it plays an incredibly crucial role in vehicle operation and is the link between a revving engine and a moving car.

But before we can diagnose driveshaft problems, we need to understand some basic principles. Instead, the transmission and axle are combined into one unit called a transaxle. However, on rear-wheel and four-wheel drive vehicles, the transmission and axle are separate.

This means that the turning motion of the transmission needs to be transferred to the axle in some form. Hence, the driveshaft. Usually constructed of steel or aluminum, sometimes even carbon fiber, a driveshaft has a tubular design to ensure it is both strong and lightweight.

However, because of driveline angles and vehicle flex, sometimes the driveshaft must consist of a few parts for proper operation. Depending on the year-make-model, the design of the driveshaft may be either a single-piece or two-piece unit.

Additionally, four-wheel drive applications have two driveshafts—one that links the transmission to the rear differential and one that links the transfer case to the front differential. On a single piece driveshaft, you may have a solid connection to the axle while a slip yoke connects it to the transmission.

The driveshaft will be able to slide back and forth on these splines to keep from binding, while effectively being able to apply power. You may also have a propeller shaft up front, similar to what is found on a two-piece driveshaft, which offers a fixed mounting position on the transmission but still allows the driveshaft to extend as needed. Between the yoke and the driveshaft—and used as the connecting point for the driveshaft and the differential—are universal jointsor u-joints.

U-joints are used to manage the angles. The transmission and driveshaft sit at an angled pitch and this means that the driveshaft will need to pivot as it rotates. U-joints are what make this possible. Two-piece driveshafts do all the same things as a single-piece driveshaft, just in a slightly different way.

drive shaft problems

Rather than using a slip yoke to attach to the rear of the transmission, these are mounted in a fixed position with the use of a u-joint on the output shaft of the transmission and a u-joint on the axle. The driveshaft still needs to manage flex, and this is done between the two driveshafts instead of at the transmission. This is important for 4WD vehicles that see extreme flex—as the use of a slip yoke could actually result in the driveshaft falling out of the vehicle.

Now that we know what the parts are, we can break down driveshaft problems.Give us a call atour Drivelines experts will help diagnose this issue.

Place a spirit level protractor on the driveshaft about halfway between the transmission and the Differential. Read and record the angle shown on the protractor scale and note whether the driveshaft points up or down at the front.

Next, measure the transmission and differential angles. You must first locate a machined surface on the transmission and differential.

drive shaft problems

The surface must be clean and true, free of any nicks and burrs. Again, record the angles and note whether the angles are up or down. Once all of the components have been measured, calculations can be made to figure the operating angles and to compare angles to see if the angle alignment is correct. To calculate operating angles, you must add or subtract the component angles- that is, the relationship of the operating angles between the transmission, driveshaft and the differential, on each side of the driveshaft drive and driven ends.

This example shows 3 degrees of angle up for the transmission, 7 degrees up for the driveshaft and 3 degrees up for the differential. Elbe U. Because all of the angles are up, you need to subtract the smaller component angle from the larger component angle at each joint. The same would be true if all the component angles were down. This example is within specifications in regard to both angle alignment and operating angles. Drivelines NW. Our example shows: 7 deg. Seattle S.

This means that the transmission is positioned so that the length of the transmission is parallel to the firewall. This also means that the drive shafts are in the front of the vehicle.

The drive shafts transmit the power from the transmission to the drive wheels. When these shafts fail, you must get them replaced immediately because the car simply won't move without them. Turn the steering wheel on your Ford Focus all the way to the right or left. Due to the steering wheel lock, you may need to turn the key in the ignition to the "II" position. Look behind the wheel. On this drive shaft, there will be two rubber boots, one at each end of the drive shaft. Inspect the boots for rips or tears.

Measuring and Correcting Angle Problems

Drive shafts fail when these boots rip they eventually will rip or come apart from the shaft. Inside the boot is axle grease. This grease lubricates the joints. When the boot fails, the grease leaks out, and the joint dries out. This, in turn, causes the joint to grind and the drive shaft to fail. When this happens, you need to replace the shaft.

A bad or failing driveshaft can make it difficult to control your vehicle. Read on to learn what signs and symptoms you should be on the lookout for.

If your car exhibits any of these conditions, a trip to your mechanic is in order; they have the know-how to diagnose and fix your driveshaft problems. The type of vehicle you drive dictates what kind of drivetrain system is in your vehicle. There are different systems for rear-wheel drive, four-wheel drive and front-wheel drive vehicles. In a rear-wheel drive vehicle, the rear wheels deliver the power.

A long driveshaft is connected to the transmission on one end and the differential on the other end by universal joints. On a typical four-wheel drive or all-wheel drive vehicle, there are two driveshafts. There is the same driveshaft that is on a rear-wheel drive car but there is also an additional front driveshaft that is connected to the front differential and the transfer case by u-joints.

On a front-wheel drive vehicle, the front wheels provide the power. Instead of having a long driveshaft like on a rear-wheel vehicle, all the drivetrain components are in the front of the vehicle. Rather than using universal joints, this setup uses constant velocity CV joints. A common symptom of a failing driveshaft is an intense shaking coming from underneath the vehicle. Worn out u-joints or bushings can cause the driveshaft to vibrate.

A failing driveshaft can prevent the wheels from properly turning, making it difficult to control the vehicle. If you hear a loud clunking noise when shifting your vehicle, this is another sign of driveshaft damage. The likely culprit is a worn u-joint. If you experience shuddering when accelerating from a stop or low speed, a loose u-joint or bad center bearing could be to blame.

Not just annoying, a squeaking noise at low speeds can be caused by a u-joint that needs lubricating. A little bit of grease will get rid of the noise.

We encourage you to consult with a certified technician or mechanic if you have specific questions or concerns relating to any of the topics covered herein.The power the engine creates is called torque. The job of the drive shaft is to transmit that torque power to the wheels of the vehicle.

But if you have a rear wheel drive or four wheel drive vehicle, then a long drive shaft or propeller shaft is needed to transfer the torque produced by the engine to the two rear wheels. In the case of a four wheel drive vehicle, you may find that it actually has two separate drift shafts; one for transmitting power to the front and another to transmit power to the back.

The only way they can keep rotating quickly is if they remain weighted down and balanced exactly right. When the drive shaft begins to have malfunctioning issues, then your driving ability will be impaired.

More specifically, there are 5 common symptoms you can recognize that will let you know there is a problem with the drive shaft or slip yoke. This is usually the first symptom that people recognize when there is a drive shaft problem.

The vibrations are likely due to worn out bushings of the driveshaft. These bushings are what normally keep the drive shaft from vibrating in the first place. If the problem is not fixed soon, the vibration will get more severe. It will get so bad that your passengers will be able to feel it too.

The worst part is that other drivetrain components can also be affected and damaged. When you accelerate your vehicle, do you hear a clunking noise?

What Are the Symptoms of Drive Shaft Problems?

How about when you drive the vehicle into reverse, or even into drive? If you hear clunking noises in any of these cases, then it could mean your drive shaft has an issue and should be promptly inspected.

Often, this is a common symptom of a bad slip yoke. It could possibly be out of balance or some other part of it could be worn out. The cap seals of the bearings could have rust on them. Either that or the u-joint itself is not stable. Keep that in mind that the type of vehicle plays a major role in both the price of parts and labor. I thought it was interesting when you mentioned that a clunking sound that occurs when a vehicle is accelerating is a sign that there might be a problem with the driveshaft.

It seems that it would be important to have heavy-duty vehicles serviced by professionally trained technicians. Ford Mustangs, for one, feature rear-wheel drive and hence driveshafts.
