Why Choose Strutmasters Instead Of Those Other Guys

Do you have a leak in one of the air struts on your 2003-2009 Mercedes Benz E350 and the dealer quoted you up to $4000? It is costly to bring the E350 into the dealership every time one of these parts malfunctions. As the Suspension Experts, we knew we could come up with an affordable and high quality solution that would give E350 owners an easy way to repair their suspension. Our air to non-air suspension conversion kits are just that. Our Mercedes E350 kit includes our exclusive custom suspension warning light module, two pre-assembled front coil-over struts with Eibach coil springs, two Eibach coil springs with mounts for the rear, and two passive hydraulic fluid and gas shocks for the rear. You’ll love the kit because it is installed easily, in about one hour per wheel and requires no modifications to your vehicle and no special tools. It comes with easy to follow instructions and installation videos are available on our website for additional help. The kit saves you a huge chunk of change, too. Once you see the cost difference between choosing an air vs. non-air suspension system, you’ll know why our satisfied customers are happy they made the switch. Let’s compare three different scenarios: repairing your air suspension system at the Mercedes Benz dealer, installing air suspension parts on your E350 individually, or getting rid of the air ride headache for good and installing our coil-over suspension conversion kit. But don’t take our word for it, read reviews from other who have made the switch for first-hand feedback.

How Do I know If My E350 4MATIC Sedan Air Suspension is failing?

It’s a cold morning and you just came out to find your 2003-2009 Mercedes Benz E350 leaning or sagging. What’s going on it was fine yesterday? Unfortunately, this is a common issue for owners in colder climates and is due to the delicate nature of the electrical components that make up the AirMatic system. That being said there are three areas where you will likely see problems occur in the suspension: the relays and fuses, the compressor, and the air struts. There are many more components in the system that could fail, like your level sensors or the valve body, but are less common. First thing you want to notice is how often the compressor is running and whether or not the Mercedes is maintaining proper ride height. A faulty relay can cause the compressor to run more than normal even if there isn’t a leak in the air system. If you replace the relay and fuse you will likely need to replace the compressor and the battery, which are probably about to fail if they haven’t already. If the relay and fuse appear fine then you probably have a leak somewhere in your air system. You can run soapy water over all the components paying special attention to joints and seals to determine if there is a leak. You may also want to take note of the condition of the air strut. If the rubber is dried and cracking it will likely need replacement soon and it would be better to catch it early to avoid burning out the compressor. If you are unable to determine the cause of the air suspension problem on your E350 then you may want to take it to the dealer for a diagnostic.

Suspension Components List

The 2003-2009 Mercedes Benz E350 (4MATIC Sedan) is built with the following suspension components:

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Electronic Shocks (x2)- shocks abosrbers whose dampening capabilities is controlled by the suspension control module in order to ensure proper wheel-to-ground contact.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Electronic Shocks (x2)- shocks abosrbers whose dampening capabilities is controlled by the suspension control module in order to ensure proper wheel-to-ground contact.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Air Springs (x4)- (models with air suspension only) commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time..

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Struts (x2)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.; the air spring assembled on top of the strut is commonly referred to as an air strut.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Height Sensors (x4)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Air Lines- tubes that run from a compressor to the air struts which carry pressurized air to the air bags.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Solenoids (x4)- usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Compressor Assembly- creates/sends pressurized air to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

2003-2009 Mercedes Benz E350 (4MATIC Sedan) O-rings- although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
