Critical Failure Risk
The crank hub, connecting the crankshaft to timing gears, can slip under high loads. This disrupts engine timing, causing misfires, power loss, and potentially catastrophic engine damage. Symptoms include rough idling and check engine lights. This is a significant concern, especially for modified or aggressively driven vehicles. Preventative measures include regular inspections and considering an aftermarket crank hub upgrade.
Early detection can help you avoid a $3,000-$3,500 repair.
