How long do driveshafts last?

While there is no set lifespan of a driveshaft, it typically can last about 75,000 miles. Keep in mind depending on the vehicle, and wear and tear you may get much less or much more.

What causes drive shaft failure?

Improper stiffness matching between the left and right smooth shafts, which results in a larger torque transmitted to the right spline, is the root cause of the drive shaft failure.

Do drive shafts wear out?

If the driveshaft universal joint (U-joint) or bushings wear out, it can cause excessive driveshaft vibration. Driveshafts are finely balanced before installation to ensure they do not vibrate. Any sort of vibration indicates an issue.

How much does a driveshaft cost to replace?

In most cases, a new drive shaft costs somewhere between $300 and $1300. Fortunately, it only takes about an hour to replace it. A repair usually costs much less, around $200 to $300 including parts and labor, but this also depends on how many parts need to be replaced.

Why would a drive shaft needs replacing?

If the rotation fails or speeds up too quickly, then it will cause issues with your driveshaft. What is this? Perhaps you have a bad U-joint or your bearings have rust on the cap seals. This may require you to replace your entire driveshaft if the damage is too significant.

Should you replace driveshafts in pairs?

On a high-mileage vehicle with a bad CV joint or boot, it's often a good idea to replace both shafts at the same time. Often, the right (passenger side) shaft fails first because right turns are at a sharper angle than left turns, and right turns are more common than left turns.

How do driveshafts break?

Frequently, if a car hits another car or objects with its rear wheels (like when you back into something), the impact can cause the driveshaft to break. The same thing goes for hitting a curb – that shock alone has been known to ruin drive shafts.

How do I know if my drive shaft needs replacing?

Is it hard to replace a driveshaft?

Changing a drive shaft is actually a simple task that a home mechanic can undertake without too much trepidation. It's just a case of being thorough, being safe, and of course having your trusty Haynes Manual to hand.

Can a broken drive shaft damage transmission?

A broken axle can damage a transmission because the two parts are connected. The axle transmits power from the engine to the wheels, and the transmission controls the gears. The car may not be able to shift gears properly, and it may eventually break down. A broken axle can also damage the tires.

What does a worn out drive shaft sound like?

Another symptom of driveshaft issues is loud clunking noises. These noises are usually produced by worn-out u-joints. The ability of your driveshaft to rotate correctly is altered if your vehicle has a faulty u-joint. Lack of u-joint lubrication can cause squeaking noises when you drive at low speeds.

How long does it take to change a driveshaft?

That's very difficult to answer due to the multiple variables involved in removing and replacing hard to access components such as the center driveshaft on a front wheel drive vehicle like your Edge. However, in general, this type of job can often be completed in one business day; or less than 8 service hours.

How do you inspect a drive shaft?

Inspect the center bearing bracket, bracket bolts and mounting hardware and ensure they are not loose or broken. Inspect the center bearing bracket for cracks. With hand pressure only, push up and pull down on the driveshaft to check for movement in the center bearing carrier.

What causes driveline vibration?

One of the most common cause of driveline vibration are worn U-joints or slip splines, out-of-balance components, yokes out of phase or misaligned angles, approaching critical speed range, and yoke ears that are not concentric with the splines.

What happens if your driveshaft falls out while driving?

Nothing Good Comes From Letting Driveshaft Issues Linger On

So much so that the universal joints can break while the vehicle is in motion. In turn, the driveshaft can become disconnected and hit the ground. The issue can be dangerous, as the car won't be able to drive forward or backward.

How long do CV boots last?

Usually, the CV boots will last about 80,000 miles before they have to be replaced. The boots are made from rubber, which means that they will take on a lot of abuse over the years due to the high amount of heat that they are exposed to.

How long do CV axles last?

Constant Velocity Joint Replacement

Answer: CV joints last from 70,000 to 130,000 miles, and over, but technicians recommend that they be inspected periodically.

How urgent is CV joint?

Failing CV joints pose a serious risk so be sure to get your car into your auto shop as soon as possible. If there is only a small crack in the outer CV joint, your mechanic may be able to simply replace the CV boot and repack the grease, but for any major damage, an entirely new joint is necessary.

How much does it cost to replace U joints?

The u-joint replacement cost is estimated between $225 and $300. Labor makes up about $100 to $125, while the parts should be between $125 and $200.

What holds a drive shaft in place?

Connecting the two sections of the driveshaft is a center support bearing, which is a "U" shaped metal bracket with a solid-rubber machined bearing on the inside. The bearing is designed to keep both parts of the driveshaft solid in order to reduce harmonic vibration as the vehicle accelerates.

Do driveshafts need to be balanced?

Like tires, your driveshaft should be balanced to promote safe operation and prevent failure.

Will a stiff u-joint cause vibration?

Common signs of a faulty u-joint include a squeaking noise, clunking sound when shifting, vibrations in the car, and transmission fluid leaking.

Why does my truck vibrate when I accelerate?

One reason your car could be shaking with acceleration is that the engine's mounts are broken. If even one of the motor mounts is broken, this could occur, and puts more stress on the remaining mounts. Replacing broken motor mounts is one way to stop vibration during acceleration.
