The Case Construction Genuine BU3950013 Universal Cross Joint Spider is a critical drivetrain component engineered for use in propeller shafts of Case backhoe loaders. This OEM cross joint spider enables efficient transfer of rotational torque between the transmission and axles while allowing angular movement caused by suspension travel and chassis articulation.

Manufactured to Case Construction’s stringent quality standards, the cross joint spider is made from high-strength, heat-treated alloy steel and precision-machined for perfect balance and durability. Its design minimizes friction and wear at the bearing points, ensuring smooth rotation, reduced vibration and consistent drivetrain performance even under high torque and shock loads.

Using a genuine OEM universal cross joint spider helps prevent common drivetrain issues such as knocking noises, excessive vibration, premature bearing failure and propeller shaft misalignment. It is designed to deliver reliable performance in demanding construction environments where continuous load variations are common.
