Rod bearing (short for connecting rod bearing) Is the bearing where the connecting rod is attached to the rotating crankshaft.
Bad bearing? Bad connecting rod?
A main bearing gives the crankshaft a smooth surface to spin on, and a rod bearing, provides a surface for the connecting rod to rotate on.
NO! They have to be installed a certain way. If you have it on wrong it will actually be quite obvious. Keep in mind the bearing notch has to prevent the bearing from spinning in the same direction as the body of the connecting rod does. Install the cap so the bearing notch faces the same direction of rotation as the rod body does. The sides of the connecting rod are thrust surfaces as well. Install the cap backwards, and they most likely won't match up either.
If it is a connecting rod or bearing--be prepared to put in a new motor

1. Clean the bearing surface of connecting rod and connecting rod cap. 2. Clean upper connecting rod bearing and lubricate the bearing face with clean engine oil. 3. Clean lower connecting rod bearing and lubricate the bearing face with clean engine oil. NOTE: Align the tabs on the connecting rod bearingswith the tab grooves in the connecting rod. 4. Install upper connecting rod bearing in connecting rod. 5. Pull the connecting rod into position against thecrankshaft. The connecting rod may need to be rotated in order to prevent contact with the piston cooling jet. 6. Install lower connecting rod bearing in connecting rod cap. 7. Install bearing cap in position on connecting rod. Ensure that the identification numbers are stamped on the same side. 8. If you have Type A connecting rods, install two bolts and two nuts. If you have Type B connecting rods, install two bolts. The torque is very important. It's probably 40 ft pounds plus 1/4 turn.9. Repeat Steps 1 through 8 for the remaining connecting rod bearings.

Typically.... Connecting rod bearing / crank bearing. But it could also be piston slap, or flywheel.
