Standard Rubber/Metal Mounts:
* Simpler Design: These are essentially a rubber bushing bonded to metal brackets. They're relatively inexpensive to manufacture.
* Less Vibration Damping: They offer some vibration isolation, but significantly less than hydraulic mounts. You'll feel more engine vibration in the cabin. Road noise and harshness will be more pronounced.
* Shorter Lifespan: Rubber degrades over time, becoming harder and less effective at isolating vibrations. They're more prone to cracking and tearing.
* Lower Cost: This is their primary advantage.
Oil-Filled Hydraulic Motor Mounts:
* More Complex Design: These contain a hydraulic fluid-filled chamber within the mount. This fluid acts as a damper, absorbing vibrations much more effectively.
* Superior Vibration Damping: This is their main benefit. You'll experience a much smoother and quieter ride, with significantly less engine vibration transferred to the vehicle's chassis and into the cabin.
* Longer Lifespan (Potentially): While they can fail, the hydraulic components are generally more durable than the rubber in standard mounts, *provided they are of good quality*. However, they can leak fluid over time, rendering them less effective or requiring replacement.
* Higher Cost: The more complex design and use of hydraulic components significantly increase the manufacturing cost.
Why the Price Difference for your Windstar?
The substantial price difference for your 2000 Ford Windstar likely comes down to these factors:
* Improved Comfort: Older vehicles like the Windstar often benefit greatly from the upgrade to hydraulic mounts, making a noticeable difference in ride quality.
* Reduced Noise and Vibration: This is a significant factor contributing to the perceived value of the upgrade, especially if your current mounts are worn out.
* Hydraulic Mount Durability: While not always the case, quality hydraulic mounts *can* last longer than standard rubber ones, offering better long-term value despite the initial higher cost. However, a low-quality hydraulic mount can fail prematurely.
In short: You're paying more for significantly improved ride comfort, reduced noise and vibration, and potentially a longer lifespan with oil-filled hydraulic motor mounts. If a smoother, quieter ride is a priority, the upgrade is worth considering, but be sure to buy high-quality replacements. If your budget is tight, new standard rubber mounts might suffice, but you'll likely experience increased noise and vibration.
