With the retaining ring free, a forceful tug separated the floating universal joint from its housing. (If the boot is stubborn, a screwdriver can be used behind the seal to pry it outward.) Difficult to see through the black grease, the floating universal joint consists of a cross pin running through the shaft, square bearings that slide freely into corresponding grooves in the housing, and a small, stamped-steel clip that keeps the bearings located properly. Its grease was so old and tacky that nothing would slide freely and it was difficult to wipe away. The components were soaked in solvent and we used a stiff brush to scrub away the stubborn grease.
