What does a drive shaft yoke do?
The slip yoke is an important component of any drive shaft assembly. The slip yoke assembly (pictured on the right) is what allows drive shafts and PTOs to flex or “slip” with their given application. The slip yoke is also essential for allowing u-joints to rotate properly with the drive shaft. Click to see full answer.

A WORD ABOUT 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 holds the driveshaft 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.
What connects the driveshaft to the transmission?
The driveshaft itself is enclosed in a tube. Torque tubes connect the transmission and differential via a single universal joint, or U-joint for short.

What is a Drive Shaft?
A drive shaft is a most important part of a vehicle that transfers torque from the transmission to the differential, and then the differential delivers this torque to the front wheels to run the vehicle. The drive shaft is also known as a Cardan shaft, propeller shaft, or prop shaft.
Why do you need a two piece shaft?
These shafts are used to stop the driveshaft damage due to bending at high speed. Two or three-piece shaft uses for four-wheel-drive vehicles and vehicles with a large distance between the axle and engine. You can reduce the speed by dividing the driveshaft into two or three parts.
What is the purpose of a drive shaft?
A drive shaft is a most important part of a vehicle that transfers torque from the transmission to the differential, and then the differential delivers this torque to the front wheels to run the vehicle. The drive shaft is also known as a Cardan shaft, propeller shaft, or prop shaft.
What is the purpose of a center bearing?
The center bearing uses to link the two parts of the propeller shaft. In this way, the center bearing ensures the exact position of the drive shaft parts and decreases the harmonic vibration during the motion of the car.
Why is it important to replace the drive shaft?
The proper working of the drive shaft is too much important for the proper operation of the car or any other vehicle. In case of driveshaft failure, you must replace it immediately.
How to tell if your propeller shaft is bad?
If the front wheels of your vehicle don’t turn quickly or turn very slow when attempting to steer the vehicle , this is one of the most common symptoms of a bad propeller or drive shaft. In such conditions, you will need to put a lot of force on the power steering to turn the wheels.
What is the universal joint?
The universal joint is a most important part of the propeller shaft. The universal joint is also known as a U-joint. It connects the revolving shafts of the vehicle.
What is a CV socket yoke?
The CV socket yoke comes in greaseable and non-greaseable options for a CV-style drive shaft. When replacing, use the same design to maintain compatibility requirements of the surrounding parts. A greaseable socket yoke requires a small flush grease fitting, whereas a non-greaseable yoke will use a small rubber boot on the CV weld yoke.
What is a U bolt?
A U-bolt has threaded legs and is in the shape of a U. It is an industrial fastener typically used to attach a part to a pole or beam or to support pipework. It adds stability and support for inconsistent terrain and is commonly used in jeeps. U-joint U-bolt kits supply you with U-bolts to secure the pinion yoke to the drive shaft. They are sold with nuts and lock washers to ensure you have the preferred attachments for drive shafts for off-road vehicles or cars in the high-performance world. However, yokes have to be machined to accept U-bolts.
What is a slip yoke?
Typically, the slip yoke is an internal splined shaft that connects to the drive shaft. Its purpose is to transfer power from the transfer case to drive shaft. It slides (or slips) in and out of the transfer case to allow this. Without the slip yoke, the U-joints could not rotate with the drive shaft properly because it allows for the PTOs (power take-off) to flex.
What is a drive shaft bolt?
A drive shaft bolt secures the drive shaft to the axle flange. It is a strong mating point. It is a one-time use part that will need to be replaced whenever the drive shaft is serviced. When using long bolts, it’s essential to check them; if their washers break or fall off, the bolts can become loose and come out.
What is the U-joint on a transmission?
The U-joint, responsible for connecting the drive shaft to the differential. In some cases, it connects the drive shaft to the transmission, or even allows two drive shafts to attach to each other. This cross-shaped piece has a bearing at each end to allow for the drive shaft to move laterally or side to side without any driveline components breaking.
What is a U-joint strap kit?

Can You Drive With a Bad Drive Shaft?
While it is usually possible to drive with a bad drive shaft, it’s usually not very wise to do it for long. If part of the drive shaft were to snap, you’ll lose power to that axle in the best case scenario. The drive shaft may fall and get wedged between the ground and your vehicle, restricting forward movement.
What is a drive shaft?
A drive shaft (also called a propeller shaft) is essentially a long rod that is designed to transmit torque from the output shaft of the transmission to the rear differential in a rear wheel drive, four wheel drive, or all wheel drive vehicle.
Why does my drive shaft vibrate?
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 drive shaft. 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.
Why does my drive shaft make a clunking noise?
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.
What is torque in 2021?
by Kevin. (Updated on June 16, 2021) The twisting force produced by the engine is called torque. The job of the drive shaft is to transmit this torque to the wheels of the vehicle. Most vehicles are front-wheel drive, so the torque would be transmitted to the two front wheels with what’s called a half-shaft.
How many drive shafts does a 4 wheel drive vehicle have?
In the case of a four wheel drive or all wheel drive vehicle, you may find that it actually has two separate drive shafts: one for transmitting power to the front and another to transmit power to the back. This will depend on the manufacturer’s implementation of the four wheel drive or all wheel drive system.
How much does it cost to replace a rear wheel drive?
If you have a rear wheel or four wheel drive vehicle which has a long drive shaft to power the rear wheels, then expect to pay somewhere in the range of $600 to $2,000. Keep that in mind that the type of vehicle plays a major role in both the price of parts and labor.
