My early '03 (October '02) did not use any of the joints cataloged by any of the chains. After two weeks of screwing around trying parts everybody said would fit, I finally went to the local FleetPride store with all of the pieces of my seized driveshaft. They matched up a Spicer 5-188X joint that matched the factory cross dimensions and has zerk fittings. The parts and labor for three joints set me back about $120. Best money spent on the truck to date. No more launch shudder and it actually rolls!
