Sealed Power Engine Crankshaft Main Bearing Set P/N:7211M
Sealed 7211M 10 main bearing set for the 1997-2004 Jeep Wrangler 6-cylinder 4.0L and other vehicles supports the crankshaft as it spins. It meets or exceeds OEM specifications.
Worn crankshaft main bearings can show up as a knock from the lower engine, a low oil pressure light or metal flecks on the dipstick, though other engine problems cause similar signs. A look at the dipstick with the engine off and cool is a fair first check; measuring journals and bearing clearance is shop work.
As a direct-fit main bearing set, it also suits the 1993-2004 Jeep Grand Cherokee 6-cylinder 4.0L and the 1991-2001 Jeep Cherokee 6-cylinder 4.0L.
