Thrust Bearing Service
WARNING: This page is about a different car, the 1992 Geo Metro, 1991 Geo Metro, and 1990 Geo Metro. However, it is still accessible from the selected car via links, so may be relevant.
Thrust bearing must be installed on main bearing with grooves toward crankshaft, away from cylinder block. Replace thrust bearing if crankshaft end play is not within specification. See CRANKSHAFT, MAIN & ROD BEARING SPECS tables at end of article.
