This is the worm bearing kit that has the races, ball bearings, shims and a CJ side cover gasket. The kit replaces all the worm bearings (loose style) and races that are shot due to water or no oil in the box.
Note: On V6 and later 4 cylinder models they had caged bearings and this kit replaces it with loose bearings.
Note: The gasket only fits 2WD Station Wagon, Sedan Delivery Jeepster (up to 1955) and CJ models (up to 1965). For other models a larger gasket must be ordered. Either 644537 or 807476 depending on model and year.
1 Required per Jeep.
