Why Choose Strutmasters Instead Of Those Other Guys
There is a wide array of assorted parts that make up the faulty air suspension system on your Mercedes Benz E320. We know them very well because we have been performing costly repairs on them for years. But no more! We knew we could come up with a more affordable and high-quality solution- we are The Suspension Experts, after all. Our air to non-air suspension conversion kit eliminates the complicated mess of those malfunctioning parts. This kit includes one custom-designed suspension light-fix module, two new pre-assembled front coil-over struts using Eibach coil springs, two new Eibach coil springs with mounts, and two passive hydraulic fluid and gas shocks for the rear end of the E320. DIYers love it because it is installed quickly, in about one hour per wheel. The kit also comes with easy to read instructions, complete with pictures and helpful support information. The kit saves you time and frustration, but also a huge chunk of change! The cost difference between choosing an air vs non-air suspension system is massive- itâs the main reason why our customers decide to make the âswitch.â On this page, we dissect three different prices: that of repairing your air suspension system at the Mercedes-Benz dealer, that of installing aftermarket air suspension parts on your E320 piece-by-piece, and that of getting rid of the faulty air ride headache forever and installing a new Strutmasters coil-over suspension conversion kit today.
How Do I know If My E320 RWD Wagon Air Suspension is failing?
There are clear signs the air suspension system on your 2003-2009 Mercedes-Benz E320 is leaking or has failed. You want to catch the issue while the suspension is still going bad before total failure sets in. The most noticeable sign is a sudden and even height difference between different sides of the E320. Usually, you will notice sagging, one inflated area, squatting, slamming, or anything resembling these descriptors. Perhaps there is sagging in the rear but the front end remains inflated. Sometimes there is leaning from one side to the other. Overall, any issue with your E320 reaching and maintaining appropriate ride height is a red flag indicator of a bad suspension. A repair may be necessary, too, if you notice an illuminated suspension warning light or message on the instrument panel. If the air compressor has stopped working, you may need a replacement. If it is very loud and noisy, a bad suspension may have caused it to wear out. You’ll want any of these issues fixed immediately.

Suspension Components List
The 2003-2009 Mercedes Benz E320 (RWD Wagon) is built with the following suspension components:
2003-2009 Mercedes Benz E320 (RWD Wagon) 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 E320 (RWD Wagon) 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 E320 (RWD Wagon) 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 E320 (RWD Wagon) 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 E320 (RWD Wagon) Air Lines- tubes that run from a compressor to the air struts which carry pressurized air to the air bags.
2003-2009 Mercedes Benz E320 (RWD Wagon) 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 E320 (RWD Wagon) 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 E320 (RWD Wagon) Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicleâs correct ride height.
2003-2009 Mercedes Benz E320 (RWD Wagon) 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.
