Suspension Movement: It needs to accommodate the up and down movement of the suspension system, allowing the wheels to move freely while maintaining power delivery. Angle and Length Changes: In some cases, the drive shaft also needs to handle changes in angle and length due to steering and suspension articulation.
These joints allow the drive shaft to flex and change angles as the suspension moves.
This allows the drive shaft to change length as the suspension moves up and down.
Cylindrical Tube: Usually made of steel or aluminum for strength and durability.
