Detailed Description

This National 710305 wheel seal is engineered around the dimensional requirements listed for rear outer and rear inner positions on Nissan rear axle assemblies. The seal measures 1.929 in. inside diameter, 2.760 in. outside diameter, and 0.689 in. overall width with side lip, giving it the metric sizing needed for accurate fitment in the housing bore.
