Disassembly Made Easier The Tiger Tool 10102 Heavy-Duty U-Joint Puller is engineered for use with up to a 1" impact wrench providing what the company describes as "brute strength" to disassemble the most severely seized driveshaft yokes. In addition to Spicer's 1610-1880 series u-joints, Rockwell 16N, 17N, 18N and 1710 series u-joints, the 10102 accommodates the disassembly of Spicer's "Life Series"® u-joints as well as the Rockwell RPL "Permalube"® u-joints.
