The Inevitable: Wearing Out Your Clutch
Clutches wear out, and cars usually need at least one clutch replacement before the end of their lifespan. One of the biggest reasons they wear out is from people riding the clutch, this means leaving your foot on the clutch avoidably, for example in traffic causing unnecessary damage. It is better to put your clutch into neutral at this point. However, many people are already in the habit of doing so, therefore replacing your clutch can end up being inevitable.
When To Change Your Flywheel
A clutch costs money, and so does the labour, so when your clutch is being replaced and the drive shaft has already been removed you might as well have your flywheel changed. This will avoid future costs. Your flywheel is a rotating mechanical device that is used to store rotational energy. As per Quora the inertia of the flywheel opposes and moderates fluctuations in the speed of the engine, and stores the excess energy for intermittent use.
