OK, I am rebuilding a 1994 4.0L out of a Grand Cherokee. I picked up a regind crank on exchange. I have a 5 speed so I needed to install a pilot bearing. Went to NAPA and got one. Here is the problem. New bearing OD is 1.000, it slips and slides and slops around the crank, way to small. I don't have snap gauges to measure the crank, but it is very close to 1.050". I have a socket the just might tape in and it it 1.050. Only other size I could check was down to 1.035 and that was very loose as well. So if I checked online with AutoZone or anywhere all bearing are 1.000, I have searched and came up with a few 1.050 OD pilot bearings but nothing I can go buy. They have the smaller AX-15 shaft size of .560 and my trans is a .750. Does anyone have an answer as to why the regring 4.0L crank has a different pilot OD size? Seems all 4.0L have eithere a .865 or something and then a 1.000? Where did I get this 1.050 diameter size????? HELP I need wanted to drop this back in and be back on the road..
