Are you tired of the constant worry and expense associated with the complex suspension system in your 1999 Benz S500? Many owners of this classic luxury vehicle face ongoing issues with the original hydraulic suspension, leading to sagging, uneven rides, and hefty repair bills. Fortunately, there’s a permanent and cost-effective solution: converting to a reliable coil spring suspension system.
Why Consider a Coil Spring Conversion for Your 1999 Mercedes S500?
The 1999 Mercedes Benz S500, a member of the esteemed W140 chassis family, was originally equipped with a sophisticated hydraulic suspension system. While innovative for its time, this system is prone to failure as the vehicle ages. Components like hydraulic struts, pumps, and sensors can degrade, leading to leaks, malfunctions, and a compromised driving experience. Repairing these systems often involves sourcing expensive OEM parts and dealing with complex diagnostics.
Switching to a coil spring suspension offers numerous advantages for your 1999 Benz S500:
- Cost Savings: The most immediate benefit is the significant reduction in repair costs. Replacing just one hydraulic strut can be as expensive as a complete coil spring conversion kit.
- Enhanced Reliability: Coil spring systems are inherently simpler and more robust than hydraulic systems. By eliminating complex components like pumps, air lines, and electronic sensors, you minimize potential failure points.
- Improved Ride Consistency: Say goodbye to the unpredictable sagging and leaning associated with failing hydraulic systems. Coil springs provide a consistent and stable ride height.
- Simplified Maintenance: Coil spring suspensions require minimal maintenance compared to their hydraulic counterparts. No more worrying about leaks, compressor failures, or sensor malfunctions.
- Straightforward Installation: Conversion kits are designed for relatively easy installation, often requiring no specialized tools or modifications to your 1999 S500.
What’s Included in a 1999 Mercedes S500 Coil Spring Conversion Kit?
A typical conversion kit, like the Strutmasters kit designed for the 1996-1999 Mercedes Benz S500, includes all the necessary components to completely replace your rear hydraulic suspension:
- Rear Shocks: Two high-quality shocks designed for optimal ride comfort and handling.
- Rear Coil Springs: Two premium-grade coil springs engineered to provide the correct ride height and support for your 1999 Benz S500.
- New Mounts: All necessary mounts and hardware for a secure and proper installation.
- Detailed Instructions: Step-by-step instructions to guide you through the conversion process.

Understanding the Original 1999 Benz S500 Suspension Components
To appreciate the benefits of a conversion, it’s helpful to understand the components of the original hydraulic suspension in your 1999 Mercedes S500:
- Hydro-Pneumatic Springs (Rear): These hydraulic “air bags” use pressurized fluid instead of coil springs to support the vehicle. They are often the primary source of leaks and failures in older systems.
- Electronic Shocks (Rear): Damping is controlled electronically by the suspension module, adding complexity and potential failure points.
- Height Sensors: These sensors monitor ride height and communicate with the control module. They are also prone to wear and malfunction.
- Hydraulic Pump: The pump maintains pressure in the hydraulic system. Leaks force the pump to work harder, leading to premature failure.
- Dryer Assembly: Removes moisture from the hydraulic lines, but becomes less effective as leaks develop, potentially causing internal damage.
- Suspension Control Module: The “brain” of the system, interpreting sensor data and controlling the hydraulic components.
- O-rings: Small seals that are crucial for preventing leaks at hydraulic line connections.

Recognizing Suspension Failure Signs in Your 1999 Benz S500
Be alert for these common symptoms indicating problems with your 1999 Mercedes S500 hydraulic suspension:
- Uneven Ride Height: One side of the vehicle sagging lower than the other is a telltale sign of a leak or component failure.
- Leaning or Shifting: The car may lean to one side or feel unstable when cornering.
- Suspension Warning Light: Illumination of the warning light on your dashboard indicates a system malfunction.
- Inability to Maintain Ride Height: The vehicle may struggle to reach or maintain its proper ride height.
- Hissing Sounds: You might hear a hissing sound of leaking fluid, especially after parking the car.
Ignoring these signs can lead to further damage and more costly repairs. Converting to coil springs is a proactive way to eliminate these issues permanently.
The Cost-Effective Alternative: Coil Spring Conversion
Consider the significant expense of maintaining the original hydraulic suspension. OEM replacement costs for just a few components can quickly add up:
- Rear Electronic Shocks: $180+ per shock
- Rear Hydro-Pneumatic Spring: $970+ per spring
- Hydraulic Pump: $280+
Total OEM Repair Cost: Over $2,580+ (and this doesn’t include potential issues with height sensors, the control module, or labor costs).
A coil spring conversion kit offers a far more affordable and reliable solution. For a fraction of the cost of OEM repairs, you can eliminate the headaches of your aging hydraulic suspension and enjoy a dependable ride in your 1999 Benz S500 for years to come.
Conclusion:
Don’t let a failing hydraulic suspension detract from the pleasure of owning your 1999 Benz S500. Converting to coil springs is a smart, economical, and long-term solution that will restore your vehicle’s ride quality and provide peace of mind. Upgrade your suspension today and experience the difference!
