Drive shafts, also called articulated shafts, are shafts that include two universal joints. The easiest kind of drive shaft has a joint at each end. The configuration is essentially an extended double joint for overcoming distances and offsets between the drive and the motivated load. Drive shafts provide a solution for bridging angular misalignment.
Telescopic Drive Shafts
Drive shafts can 
contain a telescopic middle factor that enables quicker and simpler repositioning than likely with a rigid two-joint shaft. They allow for easy length adjustment in axial misalignments.
Spring-Loaded, Quick-Change Shafts for Reducing Downtime
Spring-loaded drive shafts contain two back-to-back single universal joints connected with a spring-loaded intermediate shaft. It allows the drive shaft to always be quickly removed and substituted without equipment. Pinning of outer yokes is not needed because the spring pressure on the intermediate shafts retains the quick-transform universal joint protect at each end.
Fail-Safe Stop Solution
Spring-loaded drive shafts can be customized to add a fail-secure solution. If the application very seriously exceeds the joint’s ranked torque capability, the drive shaft could be designed to are unsuccessful and stop in a safe trend, without damaging the electric motor.
Your drive shaft is the link between your tranny and front or rear differential. It has universal joints on both ends to permit it to rotate freely even while the rear end moves over bumps in the street. The drive shaft is carefully well-balanced when it’s mounted, and an unbalanced drive shaft can bring about problems. A bad drive shaft or prop shaft can vibrate when under lots or during deceleration. If this proceeds, your u-joints can be damaged and are unsuccessful. If a drive shaft fails and Front Drive Shaft disconnects, this may cause a lot of damage to your vehicle and keep you stranded.
THE PRODUCTS shaft assemblies are remanufactured to ensure an extended and troublefree service existence. All shaft assemblies will be entirely disassembled, cleaned and inspected.
Only those parts that meet original OEM specifications are reused. All other parts are replaced with new or OEM-specific remanufactured elements.
All shafts are reassembled with new universal joints and CV centering kits with grease fittings and so are then completely greased with the proper lubricant. All shafts will be straightened and computer balanced and analyzed to closer tolerances than OEM technical specs.
The drive shaft is the part on the lower proper side of the picture. The different end of it might be linked to the transmission.
