Get the Best Priced Mercedes S430 Struts

The Mercedes-Benz S-Class air suspension system (2000-2006) consists of four air struts that are controlled by the air suspension compressor. When this component receives signals from the height sensors, it provides the correct amount of air to the struts in order to level the vehicle. This system can be removed and replaced with a conventional coil spring suspension, using a Mercedes S430 air suspension conversion kit. Other available aftermarket modifications include lift kits to allow taller tires to be installed and load leveling kits to compensate for towing heavy loads.

Potential Problems With The Air Suspension System

Adjustment options can be "Manual" and "Automatic". If the "Manual" button fails to function, sensors under the suspension arms may have been compromised by binding, water damage or wiring problems. A sensor may be sending incorrect information to the air suspension control module. The best way to determine if that is happening is to check for fault codes, using a scan tool or an SDS machine. If the codes are not present, the problem could lie with the compressor itself, which may have caused damage to the compressor relay and blown its fuse. One characteristic of the air suspension system that is perfectly normal involves vehicle height. When the Mercedes S430 is parked for a few days, air in the system can leak out and cause the suspension to lower the vehicle somewhat. Starting the engine will cause the compressor to return it to the correct height. Of course, installing an aftermarket S430 strut conversion kit will eliminate all of these issues.

The Cost Of Strut Assembly Replacement

A dealer will charge you an average of $2119 for the strut conversion. Repair shops are considerably less expensive at $1403, and mobile mechanics may charge even less. Included in those figures is the estimated cost of the parts, which is $1081.

Rear suspension is leaking down after key off. Front seems to be OK. Is there a common issue here where I can start?

Set the suspension at normal ride height and then spray some soapy water around the rear air bags and their air line inlets. Watch for bubbles that may develop as evidence that you have a leak. Whether it's occurring on one side or both, you will then know where the problem is and can resolve it by replacing the faulty part or parts. Front shocks tend to leak more often than those in the rear, so it's a good idea to check both pairs to be sure.

Where To Buy S430 Suspension Parts And Conversion Kits

You probably already know that OEM and aftermarket parts purchased from a dealer will be more expensive. You'll save money if you get them from local independent retailers, but keep in mind that their prices include a portion of the overhead costs they must pass on to their customers. Your best choice is an online seller such as PartsGeek.com, where you're sure of finding exactly the right part at the right price. So be sure to compare before you buy.
