Universal JointThis universal-joint assembly is offered as an aftermarket replacement; contact us to verify fit for your driveline before ordering against your existing OEM number. Universal joints connect driveshaft sections at an angle, allowing torque transfer between misaligned components such as the transmission output and rear axle input on industrial lift trucks. A worn U-joint produces vibration, clunking on shifts, and eventual driveshaft separation if left in service past the point where play becomes detectable during inspection. Drivetrain technicians replace U-joints as a matched set when symptoms appear during routine service.
