Struts are the network of braces and sway bars under the Mercedes-Benz chassis. They support the weight of the Mercedes-Benz and take the brunt of chassis flex. Since cars only have the wheels to prop it up on the ground, the car strut assembly is made up of a rigid steel framework.

During torque transfer when rotational motion from the Mercedes-Benz engine passes to the drive train and on to the wheels, the strut assembly keeps tight rein of the chassis and insulates the cabin from an overload of torque. When the Mercedes-Benz hug curves, moreover, the longitudinal compression is absorbed by the strut assembly. By rerouting the force of compression away from the chassis and into the strut framework, the struts hold up the chassis from rolling sideways.

Individual Mercedes-Benz struts resist torque and chassis flex by transmitting it to the movable mounting points on the car chassis. Strut mounts on a Mercedes-Benz serve as pivot points for the struts. They work much like "passive" shock absorbers. They redirect excess torque and flex away from the chassis. But, instead of absorbing the force as shock absorbers do, struts transmit the resulting rigidity away from the axis of compression and into the flexible couplings on the Mercedes-Benz called strut mounts.

Mercedes-Benz struts are ordinarily installed across the chassis and at the heart of the drive train, where the assembly is on a high ground to function as chassis frame. These STRUTS sport rugged designs and, in tandem with the upper suspension arms of the Mercedes-Benz, reinforces the car's drive train.

Traditional Mercedes struts assembly is called strut tower brace. It unifies the strut shafts and sway bars and is often used on the rear part of a Mercedes-Benz drive train, where chassis flex and car weight peak.

The front end of the drive train, since it is involved in steering, is fitted with a MacPherson strut assembly. This type of struts can also be used on the rear end of the car if it is capable of a four-wheel drive. The strut mounts at the head of the Mercedes-Benz strut assembly have rubber joints with bushings and bearings to provide a flexible coupling.

Generally, both types of strut assemblies depend on the rigidity of the struts in the face of torque and chassis flex. To reinforce individual struts, they work in tandem with the braces and sway bars in the assembly. Since the weights of both chassis flex and torque transfers are passed on to the strut mounts, this is where strut braces and shafts usually loose grip of the chassis.

If a metallic under-chassis noise can be heard every time the Mercedes-Benz corners, it is a sign that the strut assembly has become loose on the strut mounts. Hard steering is another indication that the struts may not be in a good condition to spare the Mercedes-Benz chassis from compression.

With the regular pounding that struts and strut mounts receive, it is critical that loose strut mounts are immediately addressed. A slight slack strut mount can snowball into the caving in of the Mercedes-Benz strut assembly.
