We really can't assume a close inspection of flywheel is the norm' in the case of automatic trans. Of course the flywheel comes into play in manual trans service. If a vehicle has a history of particular part failure there are typically YouTube videos related, God and everybody knows about. That sort of thing would be looked for. Does this Ranger have a known flywheel issue?
according to the service manager at the local Ford dealer, there are not any known issues with that trans or flywheel. He agreed with an earlier post that brakes in the flywheel are usually caused by abuse or incorrect installation.
