Q: How to Service and Repair a Crankshaft on 2003 Dodge Ram 3500?
A: To service the crankshaft, measure the connecting rod bore with bearings removed and installed, recording diameters within a 20° arc and at 90° from the parting line. Calculate minimum and maximum bearing clearance. If the crankshaft is within limits, replace the bearing; if not, grind it to a smaller size and use oversize bearings.
