You will have to pull the engine to replace crank bearings. If the bearing has ';spun'; it means it has stuck to the crank %26amp; is spinning in the con-rod. If this was the case you would have virtually little or no oil pressure. If the oil pressure is in the normal range then a wrist pin is the likely culprit. This would require complete disassembly %26amp; a full rebuild.

Don't know your car but if you can take off the oil pan, you can change out the rod bearings without pulling the engine. You do this by taking off the oil pan and then taking off the rod cap and push the piston up. Change out the two sides of the bearing and put it back together.
