Different Parts of Your Driveshaft


Without its supporting components, the main driveshaft, a crucial component of how a car works, is meaningless. You will have a deeper understanding of the worth of the various drive shaft parts in the drivetrain if you’re aware of their various functions. You will benefit greatly from getting acquainted with drive shafts and their operations, whether you plan to stock substitute parts or undertake high-performance improvements.

Control Shaft

That aluminum rod is in charge of continuously delivering torque out from gearbox to the driving wheels. It enables the coupling of drivetrain parts that are normally unable to be linked straightforwardly.


This U-joint that joins the driving shaft with the differential is in charge of this. In certain circumstances, it enables 2 drive shafts that join to one another or links the axle shaft towards the gearbox. In order to enable the drive shafts to rotate horizontally or sidewards without any drivetrain components fracturing, the cross-shaped device includes bearings at either end.

Differential Pinion Shackles

To improve to a bigger U-joint or perhaps to fix a broken yoke, utilize differential pinion shackles. To provide a smooth turning of the automobile, this pinion yoke links the wheels with the differential.

Sliding Yoke

This slip or sliding yoke often links to the driving shaft through an inside splined axle. Its function is to transmit energy from the driving shaft towards the transaxle. To make this possible, it moves (or slips) into and off of the transmission casing. This slip yoke enables the PTOs to stretch, which prevents the U-joints from rotating correctly with the driving shaft without this.

Drive Shaft Sliding Yoke Felt

This driving shaft sliding yoke receives this felt band. It prevents fluids and dust from entering the slide yoke. This results in a longer life expectancy. Slipping is crucial while driving across unforgiving terrain. The felt component protects your vehicle’s driveline from damage caused by dirt, gravel, and water.

Control Shaft Bolt

This drive shaft is fastened with the axle flanges using a drive axis bolt. It has great mating potential. This is a single-use component that must be changed each time the shaft gets serviced. It’s crucial to inspect lengthy bolts before using them because if their gaskets crack or disappear, the bolts might come free.

Connector Yoke For CV

About a crank shaft inside the CV type, the CV connector yoke is available as greaseable & non-greaseable varieties. Utilize the similar design when substituting to fulfill the surrounding components’ specifications. In contrast with a non-greaseable coupling, which uses a tiny rubber shoe upon that CV weld shackles, a greaseable connector yoke needs a little flush grease connection.

Weld CV Shackles

This CV weld shackles slides into the connector yoke. This straightforward yet essential drive shaft part is also sometimes known as a tubular yoke. The piloting port on the yoke enables the connection of a tubing. Usually, it is forced onto the cylinder all at once.

Debris Cap Seal For U-Joints

This U-Joint dirt cap cover is designed to increase the lifespan of universal couplings, save costs, and lessen the need for frequent replacement of the component. The kind you’ll require will vary on the car’s make, series, season, and engine category.

Standard Yoke

Its system’s brain is the sphere and socket arrangement of such CV center shackle. Middle yokes are particularly adapted to support high angles. These are essential to ensuring the entire CV head panel’s correct operation.


Splines can be used alongside drive shafts including energy take-offs to enable variations in size during motion. They are employed to convey torque and spin. To preserve the angle connection between components, they are peaks that match perfectly with grooves of a matching piece.

Two-Cardan Shaft

This lessens the effect of erratic spinning. It aids in balancing out changes in rotational acceleration by employing 2 U-joints connected by an intermediary shaft. In essence, it uses a middle yoke to attach 2 universal joints repeatedly. The introductory shaft is no longer required when employing a central yoke.

Cleaning Fitting

These tiny hydraulic gate valves, sometimes known as lubrication nipples, are utilized on bushings to feed lubrication to internal components. They often employ identical mechanical components to accomplish the same task. There are 2 popular sizes, although grease fitting connections, which are less frequent, may also be used sometimes.

Final thoughts

Know the components, their measurements such as the driveshaft angle and their usual issues. Quick action may reduce car damage. Instead of replacing the complete driveshaft, you may just need a few specialized pieces. Waiting does additional harm.
