A universal joint for drivably and flexibly coupling two shafts together. The universal includes a pair of body members for being removably connected to the shafts, a pair of arm members connected to and extending from each body member and connected to each other to form an interlocking relationship with the pair of arms extending from the other body member, an inner bearing seat member enclosed by the arm members and a plurality of spherical bearings operatively mounted in the seats formed by concavities in the inner seat member and concavities in the arm members. The individual elements of the joint may be disassembled, repaired or replaced without disconnecting the joint from the shafts and using only simple tools.
