Buyer's Guide to INFINITI Crankshafts

How an INFINITI Crankshaft Works

A crankshaft is a hard metal shaft that runs the full length of your engine. It rotates inside the engine, while pistons located in the cylinders move up and down. Those pistons are connected by rods to rod bearing journals, which are strategically staggered to move the pistons in rhythm while balancing the engine's weight. That allows the crankshaft to take that vertical motion and convert it to the rotational movement that powers your vehicle down the road.

How to Spot a Faulty Crankshaft

If you start hearing knocking sounds from your engine, notice that your oil pressure level has plummeted, experience rougher-than-normal engine idling, have trouble starting your engine, or your engine starts stalling, your crankshaft could be at fault. Don’t let it go unattended for too long, or your engine might even seize up.
