Here's why you might consider replacement:
* Worn-out mount: A cracked, broken, or severely degraded top motor mount will lead to excessive engine vibration, poor throttle response, and potentially damage to other engine components. This is a common issue on older cars like the Stealth.
* Worn-out stopper: The stopper's job is to limit engine movement. A worn-out stopper contributes to excessive engine movement, leading to the same problems as a worn mount.
* Preventative maintenance: If you're doing other engine work, replacing them proactively is a good idea, especially if the car has high mileage. It's less disruptive to do it all at once rather than later when they fail.
In short, it's not mandatory, but it's highly recommended to inspect them. If they show signs of wear or damage, replacement is advisable for optimal engine performance and longevity. Ignoring them could lead to more expensive repairs down the road.
