A polymeric pivot body for a windshield wiper system includes a bracket portion adapted to attach a pivot shaft assembly of a windshield wiper system to a portion of a vehicle and a sleeve portion connected to the bracket portion for receiving and orientating a pivot shaft of the pivot shaft assembly. The pivot body also includes a tube receiving portion connected to and extending outwardly from the sleeve portion for receiving one end of a unitizing tube of a linkage assembly to interconnect the unitizing tube to the pivot shaft assembly. The pivot body further includes at least one I-beam portion interconnecting the sleeve portion and the tube receiving portion in a cost-effective manner while having a lighter weight and reduced stresses, and uses no tools for assembly of the windshield wiper system.
