Vent all air pressure from the air suspension system prior to disconnecting or removing any air suspension components. It is dangerous to remove air suspension components while under pressure. Failure to follow this instruction may result in serious personal injury. Any air spring which is unfolded must be refolded prior to being installed in a vehicle. Refer to the procedure. An incorrectly folded air spring could rupture, altering the handling characteristics of the vehicle. If a vehicle has been driven with an incorrectly folded air spring, a new air spring must be installed. Failure to follow these instructions may result in serious injury to vehicle occupant(s). Failure to observe the following instructions may result in a sudden failure of the air spring or suspension system. Any rear spring which is unfolded must be refolded prior to being installed in a vehicle. The air spring refolding procedure should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly folded position. Incorrectly folded air springs found on vehicles during pre-delivery inspection or after use must be installed new. Do not attempt to inflate any air spring which has been collapsed while uninflated from the rebound hanging position to the jounce stop. When installing a new air spring, care must be taken not to apply a load to the suspension until springs have been inflated using the air spring fill procedure. After inflating an air spring in the hanging position, it must be inspected for correct shape. 1.NOTE: The vehicle must be positioned on a suitable lifting device prior to deflating the air suspension system. With the vehicle in NEUTRAL, position on a hoist until the wheel and tire assemblies are slightly above the ground. 2.Using the scan tool, vent the air springs. 3.Remove the air spring retainer. 4.Detach the air spring from the rear axle. 5.Remove the air spring in the following sequence. 1.Disconnect the air spring solenoid electrical connector. 2.Compress the quick connect locking ring and pull out the air tube. 3.Remove the air spring.

An air strut with separable air springs If your vehicle offers a separable air suspension (Audi Allroad A6 C5, Mercedes-Benz W164, BMW X5, etc.), you should regularly (about once a week) lift the car to the maximum position, and remove dirt with a high-pressure cleaner (keep the cleaner at a distance to the air spring about 30 cm/12 inches, otherwise water pressure can damage the air spring). The highest position may vary depending on your model and regulation options. Therefore, please test this by trying the different modes available to you (Sport, comfort, dynamic, off-road) and choose the one that sets your vehicle to the highest position. The dirt will most likely be found under the fold of the pneumatic chambers. If you find a frozen layer of bitumen on the piston guide (the part of a strut on which the air spring is installed), it is recommended to clean it as well. Whenever possible, avoid riding on fresh asphalt, as fresh bitumen mixed with sand immediately results in a build-up of abrasives on the piston and in turn contributes to accelerated wear and tear of the air spring. A complete air suspension shock Many cars such as Mercedes W220 or W211 are set up with a complete air strut - shock absorber and air spring visually form a complete spare part. In many cases, you can easily recognize these by the metal cups with which the air spring is tightly mounted. To best avoid any damage, we highly recommend to regularly check the condition of the dust protection seals of the air strut. What is the difference between an air spring and an air strut? The air spring is a part of the air strut. Some vehicles (e.g. Mercedes ML) allow you to change the air spring separately. At our online shop you have the opportunity to buy either the whole air strut or only the air spring. For some type of vehicles it is not possible to change the air spring separately. In this case the whole air strut should be replaced. Which side of my car is the Right and Left? The right and left sides of an automobile are determined as if sitting in the car facing forward. Thus, the left side is on the left when sitting in the car facing forward, and the right side is on the right. For American cars, the driver’s side is on the left, and the passenger sits to the right of the driver. For cars in Japan, Britain, Ireland, the Bahamas and some other former British colonies -- where they drive on the left side of the road -- the passenger sits on the left side, and the driver (along with all the driving controls) is on the right. What does 4MATIC mean? 4MATIC is the marketing name of a four-wheel drive system developed by Mercedes-Benz. It is designed to increase traction in slippery conditions. What does AIRMATIC mean? AIRMATIC is a Mercedes-Benz trademark for vehicles with air suspension systems. Compared with a conventional steel suspension, the AIRMATIC air suspension provides advantages in terms of handling safety and ride comfort. The AIRMATIC air suspension automatically adjusts the damping force on each wheel according to the current state of the road. What does ABC mean? ABC (Active Body Control) is a registered Mercedes-Benz trademark. It is a high-quality suspension system, which automatically adapts the suspension setting to the respective driving situation. There is also a crosswind stabilisation integrated in ABC systems. How can I see if my vehicle is equipped with AIRMATIC or ABC? You can check which suspension you have by opening the bonnet of your car and examining the top of the shock absorber. If your vehicle is equipped with AIRMATIC, you will have obvious air lines leading from the top of the shocks: If your vehicle is equipped with ABC, you will have small black electrical plugs leading into the top of both shocks: Features and Benefits: Direct Fit Replacement - Guaranteed to fit and function for your specific application Highest Quality Materials Quality Tested - built to a strict level of product standards. 840463 Item Specifics Placement on Vehicle Left Right Rear Type Air Suspension Strut Fitment Type Direct Replacement Package Box Single Weight(LB) 18.298 Upper Mounting Isolator Included No Isolator Required Lower Mounting Isolator Included No Isolator Required Upper Mount Type Stud Lower Mount Type Base Cup Included Hardware None Drive Layout Front Engine RWD & 4WD Platform W251 Custom Bundle Yes Material Iron Aluminium Alloy Rubber Quantity 3PCS Manufacturer Warranty 2 Years OE Spec or Performance/Custom OE Spec Adjustable Yes Features Sealed Brand Sport-autoparts Manufacturer Part Number CA840463NS01 Interchange Part Number Air Suspension Spring Bag, Air Ride Spring Bag OE/OEM Part Number 2513200025,2513200425,2513200325,2513202604 Superseded Part Number 2513201204,2513201304,2513202004,2513202104,2513202704 Return Policy 30 Days Free Return Or Exchange Discount Targeted Disounts Terms (1).Targeted Discount Terms only apply to auto parts purchased from CARMASUSPENSIONS, which only includes suspension kit, control arm, tie rod end, ball joint, sway bar, stabilizer link, pitman arm, idler arm, steering center link.
